I hope this hasn't been beat to death but I was unable to find a definitive answer with the search...
What wire should I tap at the ECU for the signal wire for the Autometer Air Fuel guage? The color would be best, I've heard "the fat white one"...
Thanks for any help/info...

"in the trash" not a very useful gauge really, but it goes to the solid white wire.. don't recall the pin # anymore

 

no, use a wideband A/F for tuning.

 

Thanks.

Thanks

I really need some dyno time but my tuner is in Cali and I am in Idaho. Not cool but it pays to have people who know what they are doing.

Lambda sensor? Most chassis dyno's should have one right? I think I have to cough up the $125 for 3 passes can you beleive these prices!

 

No tuners closer than that?? Most places with dynos have widebands these days.. $40/3 runs at the next FL dyno day with wideband

 

No tuners I trust around here.

I get all my **** in Cali when I visit home. 15 hour drive, but I am 100% happy with the work so far and I havent had any problems......I have to get my 98 P73 ecu wired up still but in the mean time I want to run a little leaner for just a little more power.

I have an AEM shortty ram, DC 4-2-1 POS header, tanabe racing medalion exhaust...a VAFC and an Si ECU....on streets in 100+ degree weather I have hit a 14.4@99 w/2.4 60ft with 8000 rpm fuel cut I know I can do better.......but I think the fuel tuning (or lack of) is slowing me down.

Should I just check the plugs and see if they look off? Right now I have the VAFC set to a 3% correction factor.........should I lower it? AM I feeding it too much fuel?

 

Hate to bring this to the top, but I found one solid white wire, it appears to be the same size as most of the other wires, not bigger. Is that the right one? I'm asking because I cannot currently start my car yet. When I turn the key to the "on" position the Autometer guage flashes all the way through the LED's and the last green one stays on. Is that what should occur when the key is in the on position and the car hasn't been started yet?
Thanks a lot!

yes that is correct, it will stay like that for about 30seconds until the o2 sensor warms up. and yes it is the solid white wire.
