Holley EFI tuning and wiring

[CarlC]

Unfortunately, the Sniper does not have the required pwm- output as an option. If you have not purchased a system yet, I would highly recommend going with the new Terminator X Stealth. It uses the Terminator X ECU, which does have the PWM- output available. Better still, do a multi-point system using an Edelbrock EFI intake, couple that with a dual-synch distributor, and Terminator X ECU, and have a fully sequential system on your Pontiac engine.

Can the Sniper output a 0-5v signal based on engine temperature? Example:



185* = 1.5v
190* = 1.7v
195* = 1.8v

Etc.

Andrew, do you have the pins/plugs necessary to shorten the universal harness that come with the Sniper, to a specified length?

I don't sell any hardware. What exactly are you trying to do?

Nope. The Sniper has 4 outputs that are simple ground side triggers.

Andrew was awesome with my car. Extremely helpful and answered all of my stupid questions . I actually need to send him a message again! lol

The HP and the Dominator ECUs can be configured to output a pwm+ signal, which would effectively do this, if the duty cycle math was figured out.

Hi Andrew I have a 68 camaro with a 540 using Holley HP. Would like to see if you can help me get this running right.

Hi Ken.

I responded to your PM. Thanks for the interest.

How does the mail tune in process work? I have a sniper on a 300hp ish sbc, its nothing fancy. Its hard to start , doesnt matter if its cold out or hot. I have to cycle the key 2 or 3 times and wait till the pump is done priming to get enough fuel in the system to start. Been messing with it for almost a year now and I honestly just want to throw the system in the trash.

I'd like to shorten the 'one size fits all' harness to a specified length so it fits better in the engine bay. I'm not looking to buy hardware. I'd like to send the harnesses to a professional to be shortened.

Can the pwm signal voltage be fixed to a specific voltage, say 5v or 12v? If so, this will be super easy to use with a PSM fan controller.

Perhaps also build in tables that can control the fan when the AC is on as well?

The PWM+ output is 12 volts. From there the fan control strategy can be configured in many ways and can certainly include the AC, VSS, and even oil temperature. It's just a matter of having the data as inputs to the ECU.

I could use your help on my ls swapped 1988 trans am. It has a lq4, th350, 9” 4:11 gears, Holley hp. What is needed so you can remote tune it?
