Everything in every car (some are the exception such as honda vtech solenoids or gm fuel pump relays) is taken to ground. All the switching from the ECU is done to ground, this is safer for the ECU in the event of a short circuit and prevents voltage abnormalities as the ECU is not providing power (12v +)to a load.ok so just a ground activated relay off the MS wire labeled FAN.
sorry it just seems backwards as to what im used too
Do you understand the timing verification process with the MS? you do not pull the spout, in ignition options- top right of the box- "fixed advance' set this to fixed timing instead of use table. then open the trigger wizard and use it to get the timing set, you want to match whats in the black box with the balancer reading.found a leaking v band on the passenger side header. broke when i took it off so i just ordered a new one.
once i get that on gonna try and verify the timing with MS and calibrate the wide band. this thing will make your eyes bleed if you let it run in the shop to long.
Just keep at it, I installed/played around with my PimpXS all season last year and although I am by far an expert with it
I am definitely more comfortable using it. A lot of thanks to a91what, he is always quick to answer questions.
Likewise with wife,kids,dog,house ….fortunately my Mustang is not a daily driver so the only pressure to get it
done is my own.
18:1 would be lean (air : fuel ratio)sorry, I ment while I keep it idling with my foot its at like 18.00 or better if its idling its at 11.8 or so. I sent you a PM
