Ok. Got it running better; but, my idle is still a little lean for my liking. ~15.2. On my first test drive, I noticed that my afr's hit ~10 in third; but, not in first or second. I'm a little puzzled at that one... Now I have to get my 550's in because I'm sure my 440's are begging for...

I am an Electronics Technician so that'd be right up my alley!! I'll search around; but, if you can remember where you posted it, please send me the link!

I'm running v4.4 My current problem is at idle. It leans way out (16-17) and starts to stumble. All the connections are right and the maft is set to factory defaults. Something I did notice is that my TPS only hits ~2.5v at WOT instead of the 4.9v that the maft pro manual speaks of...

Thanks for confirming that!

If you're venting to atmosphere, that will explain a lot of the popping. And i third the suggestion of getting that lexus afm out of there till you get 550's!

I'm down to my last wire and can't figure out where it is. The maft instructions aren't clear enough for me to figure this out. I know...I'm a little slow... ;) So, where is the HAC wire location so I can finish my install? 91 Turbo 5 Speed and I'll be running the maft in AFC mode. For...

You are the man jetjock! Thank you! :D

Hello, I'm installing my MAFT Pro and need an ECU pin-out. My maft instructions did not come with one. Anyone have a quick link to it? I have a 91 Turbo 5 Speed. I've been looking through the TSRM without luck. Sorry; but, I'm trying to get this done before the sun goes down...

^^^^^Luck-eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!!!!! :D

I'll see what I can do. It'll be a few days though. If you need it done faster, hopefully someone else will step up. ;)

What do you need done exactly?

I have that setup in my car. Let me know if you need pics and I'll post them up.

What did your instructions say about your wb sensor location? I just installed an AEM and the instructions stated that the sensor had to be mounted 18" MINIMUM downstream from either the turbo or manifold. You're running the LC-1 so it may be different; but, I doubt it will vary all that...

Just for reference, my numbers and mods are in my sig. That was untuned.

See y'all there!

The CPS is fairly easy to change. Loosen the PS Res bracket and pull it out of the way and you should be able to pull it out. Removing adjacent hoses and such makes it easier though... And of course you'll have to check timing after a CPS is replaced. Consult your friendly TSRM for details...

No arguing that!

Maybe this would be of help. http://www.mkiiitech.com/forum/showthread.php?t=1001
