Have a question about this product?
I have dual exhaust all the way back, would an "H" pipe work for this system, or can i just put the o2 sensor on one side? Aslo does the handheld programmer have to stay connected for the system to work?
By Jeremy P. on March 10, 2018AnswerYes, we recommend installing the O2 sensor 8-12" down stream of the header collector, before the H merge in your exhaust system. After you program the ECU with the handheld, and do the initial throttle position and IAC set procedure, you can disconnect the handheld from the ECU.
Can the Holley Sniper EFI control electric cooling fans? The fans would be an add on for a 1970 Mustang. Also, can the Sniper be programed to shut down the a/c compressor on full acceleration? Thanks. Rich Harden
By Richard H. on July 9, 2018AnswerGreat Question Richard, The answer is both. Here is a link to the instructions, check out page 17, it tells you what wires you will need to utilize for both functions. http://documents.holley.com/199r11031r.pdf
