ok thanks for the diagram but i cant understand it. could you just tell me which diagram is for the ecu box behind the glove?

 

Do a search for AFC diagram...loook for posts by rhyzin, he took an actual photo of the ecu and labeled everything quite well.

 

Nope. I've never spent any time trying to read one and I'm certainly not going to learn at work. Possibly someone else could help you, but asking someone to name all the pins is an awfully big favor. You may want to find out exactly what pinouts you need, ask for them, and not worry about the rest if you want a quick answer.

 

here, this should be it. i feel helpful today. just got my wisom teeth pulled an hour ago. legal drugs are great!

thats the one!!!

 

damn thanks for the help ppl. i actually saw this thread while searching but i guess i didnt let the picture load and skipped it. ill go install the guages and hope everything is right.

 

Out of curiousity (and since it's related to the AFR guage install) where does the stock AFR reading come from? Is it based on the MAF value or does it actually measure like a narrowband O2 sesor?

 

comes off the O2 bung on the header, but I noticed it wouldn't read if the MAF wasn't connected.

 

oh boy, do i feel great. good luck with the installs.

 

for those with an automatic, here's the harness diagram for the m7-e

 

ok i have my tach hooked up to the ecu rpm signal but its 200rpm off. its about 100 rpm off under 2k but above that it gets about 200-3-- rpm off. i have a pivot tach. its suppose to be good but it is not reading right. could it be that the rpm signal in the dash is off? or is the tach messed up? any suggestions?

 

the rpm on the dash is wrong. my dash rpm is 200 under what it says on my SAFC. i think i trust my SAFC more since it's digital.

 

ok good i think thats makes me feel better. thought i hooked it up wrong or something. ok completely off topic but i was driving in rain today and then my motor out of nowwhere kind of bogged or something for like 5 secs. is this water getting in the intake?
