Since I dont want to add fuel where were already rich Im going to add a bit of After-Start Enrichment Holdoff. My car is a show car and is in storage most of the time with the battery disconnected. Ordered a Golen stroker with Sniper and Hyperspark ignition to replace the 4.2 in my 89. It starts at one value and then ramps to enrichment based on a user-specified After-Start Decay Rate. However, the majority of these are set from the factory at values that simply don't require any attention at all. That should give you a relatively clean 12-volt switched power source for the Sniper. check out the. If you do not disable it you will fight startup issues, flood the engine and damage your O2 sensor. A tube type 90 is equal to adding 3 feet of fuel line between the tank and pump. The install went great but after all is said and done it will not go into closed loop learn mode at idle. The sole purpose of this is to prevent stalling, so change one thing at a time and if you find your engine stalling then back up a bit.The four key settings:1.) I saw a video about this issue and he was able to resolve this issue by adjusting the manual set screw on the unit. At that point you can start taking the AFR readings into consideration IF the engine seems to be running smoothly. Bradley Iger. Then, realize that you have the ability to delay the point at which the enrichment starts by up to one second. Pin 30: To Battery That's what the fuel prime is all about. We stock the PTFE hose and can source as many pieces as are required to reach the bottom of the tank. Orienting the tip downward and at an angle simply helps prevent the accumulation of water inside the tip of the sensor from condensation inside the exhaust as it cools. Connect the crank and run wires together and all should be good. If so then it is (regardless of what the O2 sensor says.). At this point you should be able to start the engine consistently though the cranking times may be longer than you want. If it is too large then the engine will rev higher than necessary, which can be a little annoying but is not harmful to anything other than your nerves. Looking at the 4500 sniper and I run Super Street 10.90. Latest Articles. I'm worried that the engine will stall at idle. Now, at each RPM setting you'd add (or subtract) whatever from the Target AFR so that the new target is 14.0:1. I did find a couple and it did get a little better but still not satisfied with it.What is the ISC hold position for and why is it set @ 30? Set the X Axis to RPM5. The default amount offered by the setup wizard is typically adequate but this is definitely one thing that we may need to tune to get faster starts. Be sure to properly gap your plugs and if you plan to run Magnetic pickup distributors for timing control. But you can extend the leads using wires of an equal or heavier gauge. Nice catch, Ken! The Ordering process was so easy and non-painful. First, there is the obvious--the system has to learn. Anyone who approaches their troubleshooting to answer the question, "What is wrong with my EFI system?" Not perfect but not bad. I am in the middle of plumbing my new sniper throttle body system. Why? #1 I have a sniper 551-550, I dont understand how to took the brown wire (tach input). Run the switched 12-volt back as close to the ignition as possible. I have two questions at this time: 1. Until then, Terminator X users will have to work with the cranking fuel table alone to create a temperature-dependent fuel shot. So, yea it gonna ALWAYS be hard to start!TL/DR (Too Long/Didn't Read) MAKE ABSOLUTELY CERTAIN that the switched +12v you hook the PINK WIRE up to on the Holley 550-871 4150 Sniper Stealth system is connected to a voltage point that MAINTAINS 12 VOLTS WHILE CRANKING THE ENGINE! Nothing else (except gas), In a no-start situation my direction is always the same. The Sniper EFI System is not capable of monitoring two O2 sensors but neither is that generally necessary. Thanks for the kind words, Tony. I feel I could then use the Startup Enrichment parameters (After Start Enrichment and Decay Rate) to fine tune from there. Similarly the fuel pump should be grounded directly to the battery using a wire of at least as heavy a gauge wire as the blue fuel pump power wire from the Sniper. You'll note that the pressure drops at that point. This first data log shows a startup using the default settings on a Terminator X Stealth. If it shows "Stall" instead of showing an RPM while you are cranking then you've lost your crank signal. Resistance results in heat and heat results in more resistance. Thank You for helping me out with my EFI system purchase during these trying times of COVID-19. 12/02/2009. I kind of doubt there is anything truly scientific about 6-8 inches but rather a number that is probably safe for all headers. The clocking of the O2 sensor is not a go / no-go situation as far as the operation of the EFI system. Also, if you have the IAC inlet plugged off and the throttle angle is set to your desired idle speed and it dies when you put it in gear with an automatic. Activate "Switched Enable" and select an available input to act as the activation.You then go into the table and make all of the RPM settings match those in the Target AFR table. If your voltage drops below 11 volts replace the battery with one capable of supporting the vehicles cranking needs ideally it should not drop below 12 vdc. Then draw the power for the relay directly from the battery. Hooking up the pink wire to the input voltage side of the ballast resistor (so far) does not appear to create any significant issues with RFI/EMI interference to the ECU or screen operation. Chris, this is going to be an easy one. Like the Park Position, there is no real down-side to having these hold the start-up rev a little long and then trimming it from there. 4.56 rear gear and total weight is 2825 with me. It will add fuel based on the temperature and won't affect your warm start.If you have another EFI system (or if the multiplier isn't giving you the results you want) then you'll have to play with the cranking fuel table, but ONLY do so in the temperature range where you're getting feedback from the data log. Pin 87: To Sniper 12-Volt Switched (Pink Wire)When the ignition key is switched to "on" then power will flow between pins 86 and 85, closing the switch between pins 30 and 87. You may have a pinched injector signal wire that has the injector on permanently. Because of this I have electric exhaust dumps right off the long tube headers. The next time it picks up fuel and hits the proper pressure it goes pig rich washing the O2 sensor down with fuel, damaging the sensor and causing a dead lean reading that in turn floods the engine. May 23, 2022. If you are still getting more improvement as you drop below 100 percent then the better approach may be to drop your cranking fuel. Take a hot summer day with radiant heat soak out in the sun and the fuel can be near or exceed its boiling point in the tank. Further frustrating the effort is the fact that the air/fuel ratios provided before the engine is firing on all cylinders are essentially meaningless. Start by increasing your TPS and MAP ROC blanking values. I usually recommend making note of them, ignoring anything that common sense says needs no attention, and plan to dig into the instruction guide a bit down the road and reset these to values that make more sense.Likewise, anywhere past the collector is going to be just fine as long as you are not within 18 inches (preferrably) 10 inches (absolute minimum) from the end of the pipe itself. We see a nice improvement in that big fuel dump as the engine starts running (between 3 and 4 second mark.) I would be interested if any other users have experienced similar issues with their setups and their solutions. So here's how I'd do it:Pin 86: To your ignition switch (12 volts) Quick to respond and very knowledgeable. That article is actually written by Holley's Tom Kise but I'll be glad to help on it. Fortunately, Holley has another product that can solve that: Hydramat.. Hydramat is not inexpensive but you won't believe what it can do. Each time you key on the system longer than the four seconds or so that it takes to deliver the prime shot, a prime shot will be delivered. That added fuel is called after-start enrichment. Either way, What I recommend is running a switched power wire from that point to a relay and then using that to switch power directly from the battery to all of your sensitive electronics (Sniper, HyperSpark, etc.). My car idles beautifully @ about 800rpm. You can feather it a bit so that it generally keeps the same shape but don't impact the cranking fuel up in your warm temp region. Thanks! Hello, There is really no room for error on this. I know it's only 2 feet but ever inch counts. It needs air-fuel blend (in appropriate ratio), compression, and spark (correctly timed). How Sniper EFI Helped Get The Andersons' C10 Project Back On Track. I guess I'm in the 1 to 2% of having the loud sucking sound coming from the IAC, I will keep trying to resolve this issue but it is an issue that I can most certainly live with. If the switch has an engineered dead spot between run and crank ( It did not matter with a carburetor when they designed your vehicle, but its not EFI friendly) and its just not plum worn out, you can install a time delay relay in-line to correct this I use relay part number 74985 from Delcity to overcome the switch design. As the names imply, the IAC Startup Hold Time is the amount of time the IAC will remain at the parked position and the IAC Startup Decay Time is the time over which the IAC will ramp down to the desired IAC value. This is a huge improvement over what we got initially. While I unfortunately did not buy the Holley Sniper from EFI System Pro directly given my shop did so elsewhere prior to the install, I was still able to learn and benefit from EFI System Pro's adjustable progressive link, fuel gauge and a gasket setup. The engine starts and idles great. At least not right away (after time-delay set in relay). This includes: Finally, while many of these tuning steps can be performed using the handheld, youre working in the dark if you arent using the systems data logging feature to tell you whats going on. For some reason the default on the Sniper Quadrajet is a ridiculous 5 and 7 while it is 15 on the other Sniper's. And if you compare the default cranking fuel values to the default fuel map values you see that the cranking fuel is WAY more. i can hear the pump, but nothing is coming through the fuel line. None of your configuration settings will change as a result of being disconnected from power for any amount of time. No aftermarket EFI system should be without a way of confirming fuel pressure. Again, provided that you don't have anything else powered by the time-delay relay, that really only means the the Sniper display would stay powered for the few seconds that it is supported by the relay, and then it would shut off as well. Free ground shipping regardless of order size! Basically lean everything out by .5 and it should help a lot. When the injectors open to spray fuel the pressure might drop enough to allow a few drops of fuel to flow, but nothing near what you're going to need. This is most easily done using the blue fuel pump wire. Good luck! Much appreciated! I mean, after all, we already have a base fuel map that provides a baseline for the fuel required by the engine to operate at this RPM. Capability Range: Professional Price Point: $$$. Advanced throttle body injection systems capable of transmission control and more. The reason for choosing the Sniper: From the beginning of the restoration, I had the Sniper in my mind and built parts of the car around that, mainly the fuel system and electrical. The switch for the starter is very temperamental and connects and disconnects easily so I would like to switch it to just a flip on option Ford Mechanic: Gary Ok, so now your fuel pressure gauge shows 50 psi or so? Sure enough the pink wire DID NOT have voltage when cranking. Ill check the coil and see if anything else is attached. Now were getting there. I've gone through all the steps and cannot seem to solve the problem. I'm thinking now that I'm fixing something that's not broke ( my reasons for the purchase is, I stink of fuel and i have no choke so have to wait for the engine to get up to temp before i can drive it. Sounds like it is "only" burning through the initial priming shot. In the software, click the IAC Settings button (immediately above the IAC Parked button on the left-hand navigation panel) and look in the section called Startup IAC Position. Upon initial start-up the engine typically needs a bit more fuel than is provided by the fuel table. That helped. Awesome Article. (Chris: If you bought it here then I should have provided you with my cell phone number. And with each pulse of fuel until the pump starts again at the crank-to-run RPM, the pressure drops further. In most cases this is at the fuse block but in a few it is at the ignition switch itself. Chris is my go to for any issues that arise with my sniper. seems to be running rich at a idle. I have a sniper 1250 with a msd 6014 and a painless rocker panel . Like many others, EFI System Pro allowed me to dial a new Holley Sniper. This is why most OEM EFI pumps are in the tank. A throttle linkage extender and a progressive linkage kit. Don't hesitate to call, nights and weekends included.). Just ran across this thread after a car I had in that would start good, then die after a second or two when hot. Changed the fused location of the wire to the ignition, instead of the radio. 1964 Chevy Nova, 383 Stroker, AFR 210 Heads, Ford 9inch w/TrueTrac/3.90 Gears, Powerglide Transmission. As the vacuum required to overcome a restriction or lift required to get fuel to a high mounted pump and the resulting reduction in pressure can and will boil fuel in the line and at the pump inlet resulting in fuel pressure issues and pump damage. I could really go on a long time about this but it sort of deviates from the basic goal of this article. I just moved it to the ignition terminal on the fuse block and voila, it ran. The mid-way point between -40 and 160 degrees is 60 degrees, not 40 degrees. FE 390 that currently has a Pertronix distributor with the Ignitor 2 module. I'm all eyeballs! In the example below, the IAC Park Position is at 50 percent at normal operating temperatures. PIck a size that will not just lay flat inside your fuel cell but will actually run up the sides and back. Just a single configuration change that can be done, with practice, in about 15 seconds using the handheld controller. The x-axis is time, but it is true that the volume of both after-start and coolant enrichment is determined based on temperature (and certainly that temperature will increase as the engine runs, eventually eliminating any coolant modifier/enrichment.) If you're installing a Sniper EFI system and almost ready to crank it over for the first time, this is the video for you! Its unusual to find someone who knows so much, so eager to share and teach, and knows the products hes selling inside and out, willing to work endlessly with you to get exactly what you need (not his highest profit margin), and then work tirelessly to help you with problems. All it knows is what it sees in the pipe. Free ground shipping regardless of order size! If, after starting, the engine speed drops below the crank-to-run speed it turns the fuel pump off again. Figure out what it's not getting and the find out why. The xflow instructions state it needs 60 psi. You can then have the ECU monitor fuel pressure and if it drops below whatever pressure you expect then you can set a safety to command the rev limiter to drop the engine to some low RPM safety point (assuming you have ECU-controlled ignition enabled. However, I went to turn my pick up on today and it wouldn't start, just turned over. Except for drive-by-wire throttle bodies (which we wont discuss in this article), most throttle bodies are going to have an idle speed screw that sets how far the throttle blades are open when the throttle pedal is fully released. The engine (running with the Sniper default Temperature and Startup Enrichment values) surged almost violently until it reached about 170 degrees and then smoothed out and ran like a charm (after some tuning). Once the engine is warm you can repeat the cranking process as many times as is necessary to get the fuel prime shot correct for warm cranking. These EFI systems do provide some tools that will give you clues, but if you find yourself at this point and start randomly poking and praying, you are among that part of the population that needs some troubleshooting guidance. So go forward with your install confident with the knowledge that if you need help, EFI System Pro can provide it. If you're getting in the 10's your asking for issues. This, in turn, will power the Sniper. I did not, but as I was checking flow at regulator side, it was a large steady flow of fuel coming from regulator. And it may have improvedor it may have gotten worse. Not some generic piece as some have speculated. But I have MSD 6 AL. Ran well on carb and electronic ignition. Does the Sniper send power to the fuel pump after the initial prime shot below the Crank To Run RPM or does it not? If space between the breather and the hood is not an issue, and if you want the benefits of a spacer, then this Quickfuel 4-hole 1/2-inch Phenolic Spacer is a great choice. I am running a wet exhaust with O2 sensor plates. But with patience you will get there. Therefore what remote TPS can be used? Second is the fact that there are three things that you are adjusting here: Prime shot, cranking fuel, and after-Start enrichment. Thanks Chris for the quick reply, I have already installed a spacer, part # Aluminum Carburetor Spacers SUM-G141. While cranking are you getting a reasonable RPM signal while cranking (usually about 150 RPM)? Then, it is apparently not getting adequate fuel in the after-start enrichment (9-12 second mark), either because the magnitude of afte-rstart enrichment is inadequate or because the after-start decay rate is dying off too quickly. Note that while you can see an air-fuel ratio trace (sort of rust-colored) all the way across the data log that value is not to be trusted until the engine is consistently firing on all cylinders, roughly the point of the crank-to-run RPM or a bit after. Do you have fuel pressure? Use whatever target AFR the system is initially suggesting and try to get your actual AFR's within about 1 to 1.5 of that value. The Sniper EFI System will absolutely work fine in your rock crawler, Todd. Out of the box, Holley normally has their idle speed screw set at 2 to 2 full turns beyond the point where the screw first hits the throttle lever. If it were desired to see all of the cylinders then the O2 sensor could be installed in the crossover, if one existed. Pin 85: To Ground Engines require three things to run. Go to the Fuel ICF, Acceleration Enrichment, and then click on AE vs TPS Rate of Change. And 10 micron filter between the pump and throttle body. First, it is fake news that EFI doesn't like big cams. Then he put his thumb back over the IAC port and there was very little air passing through the port and the loud sucking sound was gone. Holley Sniper EFI--Look, No ECU or Wiring Harness! 3.) Copyright 2017 Cyberspace Automotive Performance, Inc. All Rights Reserved. 4-hole spacers seem to work better than open spacers. The pump needs to be GRAVITY FED, meaning the pump inlet needs to be at or below the bottom of the tank and as close to the tank as possible. There must be an option that has been found to work. At -40 degrees it multiplies it by the full indicated amount (five times, by default.) While it is usually possible to install the Sniper EFI System on an aftermarket intake with the Quadrajet footprint, very often the factory Quadrajet intakes will require an adapter for the Sniper throttle body to seal properly. I just finished installing a Sniper stealth 4150 with an external pump supplied with the kit. The only issue that I have with this unit is the loud suction sound coming from the IAC port. Love the example at the end. Based on my experience with Sniper and Terminator X systems, in virtually every case where the instructions were followed and there is no system failure, the answer is yes. you will observe that they are almost IDENTICAL when it comes to AFR. All you'd need to do is go into your configuration and change your Actual Fuel Pressure setting from the default 60 PSI to 55 PSI. Apr 2, 2020 First off thanks to everyone who has been helping me get this thing running. But let me elaborate a bit. Can I use this for the return.Thanks for the help, I Had a holley sniper on this car with no issues whatsover. To be 100% honest I was having an issue prior and flooded it. Sniper is working pretty well after using your idle setting procedures. Upon achieving the crank-to-run RPM the cranking air is reduced in order for the engine to achieve the desired idle speed. Capability Range: Advanced If it dies again after this it must be a bad coil. O2 Sensor Mounting: The O2 needs to be mounted 6-8 after the merge in the header collector. Most current pump fuels boil around 130 degrees. Will going further help more? No timing control. Idle and cruise can be tuned leaner with "seat of the pants" feel. Can I run the pink ignition wire to the coil positive? Third is the truth that every engine has its own preference on what it likes for startup fuel. There are just turn downs after the electric cut outs. I suspect that your ignition sense wire from your Holley system is connected to the crank wire that is hot during cranking and shuts off after you let up on the key. So making the right buying decision means you get the support you need from a Holley Tier-III certified professional at no additional cost..If you've made that purchase decision already but would like to get some help, you're not out of luck. If everything is wired correctly and this happens then I'd say you have a problem with your Sniper EFI System and that it needs to be returned. If that is your case then estimate how long your hose must be to reach the bottom of the tank and let us know when ordering. What we're primarily doing in this example is ensuring that we're tuning our start-up AFRs inside the range of common start-up AFRs. Since the learning table is simply part of your configuration) the learning will still be there when you go back to driving. That's a spread of 200 degrees so half of that would be 100 degrees.
