ok i just got my fast ecu back. i sent it out to have it changed to sequential from bank to bank. i think i have to rewire the injectors. does anyone know how or have a wiring diagram on how to rewire them.

 

all the wiring diagrams are on the felpro/speedpro/fast website. look there, you will find what you need.

 

i have yet to find it on there

Should be there. I wish I could help you more but my ecu came sequential with the sequential harness. Remember that you lose you fuel pump feature with the sequential box. (you will have to wire it on either a switch or 12V+ all of the time)
I would call fast as I am not sure you need to change anything on the wiring end. It may just all be internal to the ECU.

 

cool. yeah i lost the fan and fuel pump. i have the 4 stage nos control. can you use that to trigger a quad stage?

 

You shouldn't have to change any wiring. You just have to change some dash setups on your laptop if i remember. Did they make you send in your wideband o2 to recalibrate? You will lose your fuel pump function if you don't request it. We just plugged it in started right up which is a world of difference from bank to sequential and retuned it.

i got the ecu back from fast the other day. i lost the fuel pump and fan control. and picked up 4 stages of nos control. im going to try and use that to trigger a quad stage if i can. thay said nothing about the o2. so i dont have to change anything or repin the injectors.

 

no you don't have to change anything. Trying to control the quad satge with nitrous outputs might be an issue unless you have your speedsensor running. You can send it back and request them to to switch 2 of the nitrous outputs to get your fan and fuel outputs back. You can control your quad stage by using msd dual delay timer switch and have a trigger set to the clutch or first gear. Good luck.

JUST TO LET ANYONE KNOW. YOU HAVE TO CHANGE CYLINDER 3 AND 4 INJECTOR WIRES AND REPIN THEM. FOUND THIS OUT WHEN I WENT TO THE DYNO WITH JASON. THNAKS

 

Is this the new FAST??? I originally ran the batch fire and all i needed to do was send my fast to upgrade to sequential w/ the wide band to recalibrate. They send it back and we had to add a power wire for the fuel pump w/ a relay and a switch directly to the battery. Plugged the ECU back in fired it up and recalibrated some of the dash settings and retuned and she was good to go. I was there during the whole process, it only took around 10 minutes before we started to make some partial throttle pulls on the dyno @ PFI in Colorado. Never had to mess w/ injector harness. But i had the 2002 version. Damn thats wierd, didnt mean to missinform you i guess.

I think it depends on the harness, I had a old v8 harness on my old setup, and it had 8 injector outputs. On dome's harness, he had 4 injector out puts, but , for bank to bank they were in pins s2, and t2, but there was nothing in pins x2 and w2. they were actually in pins s1 and t1. just had to re pin the ecu. No big deal just a waste of time, and since I am still in a brace it's hard for me to look close under the dash....

 

na it cool. i didnt know they made 2 different harness. thanks jason for the help. yeah a waste of time for sure. jason ill give you call when you get back from sema so we can get this car tunned. thanks again.

 

Hope all is well and your getting better Jason. I want to see you up and at it next year.
