First of all thanks for helping me throughout my install you all know who you are....OK heres my setup

BB T25 on USDM SR20DE
I have no downpipe right now....
NGK BKR6E gapped at .25
stock wires and etc...
OK first I want to apologize for getting a A/F guage but I didn;t have $150 at the time for an EGT guage, so anyway, my guage at idle is extremely lean...I am running the JWT Turbo program with 370cc injectors and stock MAF, timing is set at stock 12degrees+-2 degrees, EyE balled it....ok, I notice that since at idle I havge about 20lbs vacuum I thought the blow off valve would be a little open, keep in mind that I'm not running the turbo, I mean its on but I have the maf before the throttle and the compressor outlet is not hooked up...I don't think I'm knocking(detonating) so whats up....please help me if you have any questions or I didn't make myself clear then ask me, you can reply or e-mail me a

KENLEY_SER@yahoo.com

thanks again....

maybee you should look into an adjustable FPR.? just an idea

I STILL NEED HELP....anyone???please I'm getting restless
thanks

Is the only indication that you're running lean at idle the A/F gauge?

At idle and cruising it should bounce around. Off throttle, it goes black. At full throttle, solid green block or 2.

Sounds like you're running fine to me. Hook the damn turbo up!

Yeah thats the only indication except for maybe a unstable idle....??

at idle it goes red, then black, then it'll jump back to stoich but going back towards the red....is that fine...I hooked up the turbo but I need someone to jump start me, or push start...But i have no friends:)

at full throttle it also does what you said, solid green about 2 blocks, well thanks for your help, I'm going to drive it to the muffler shop anyway today so just wish me luck and hope that I don't blow anything....:D

The idle should smooth out over the next few days, after the ECU dials itself in. With vac at 20, you don't have any leaks to find.

Don't worry too much about the A/F. It has a mind of its own. The only time you should be concerned is when you floor it, then you should get 2 green blocks. If you don't, lift your foot.

Good luck with your ride.

I told you about getting the light bar A/F guage............anyways it is doing what it is suppost to at idle and part throttle cruising it should either be bouncing around from LEAN to RICH are staying steady at the STOICH when you are steady on the pedal.

WOT (open loop) pulls should light up almost all of your greens (RICH).

(IDLE open loop) & (CRUISING closed loop non WOT) it shold be hunting for 14.7:1 (STOICH).

Steady CRUISING should be roughly 14.7:1 (STOICH) not much bouncing around here.

It's a narrow band O2 sensor. It won't hold steady in the middle. It flips between high and low voltage when it's stoich. It won't tell you how lean or how rich you are.

Cheers,
Charlie :)
