Got a BBMAF from another member and hooked it up, knowing I would have to play with the settings to make it run right. The previous tuning settings I had was 1in 1out, single - single.

I read that you should use 1in 17out but the car didn't idle at all unless I gave it +50 and it still was slightly lean. I tried 1in and every setting out and nothing seemed to work right, even when adjusting the fuel.

Did I miss something? Is there a better setting to use? I'm did some searching (still am searching too) and didn't see anything. Any ideas? Thanks guys.

Cilffs:
IN = Infiniti Q45 = HW 1
OUT = A33 = HW 17




First things first:

Have you verified everything is working properly? (i.e., initialized, the throttle % goes up when you press it, as does the MAF value and RPM, relative to their positions, i.e. use tach as a second verifier etc?)

You are using hot wire in the set-up?


Try reversing the #'s.

 

I did not initialize. I wrote down my current settings and set the fuel back to +0 everywhere. Then it was lean at idle so I set low throttle to +10 at 650 & 1000 Rpm. Didn't check what the Neo was doing with the car off and I couldn't give it any gas without it going lean even when adding lots of fuel above 1000rpm and some settings didn't rev above 2000rpm. And yes using hot wire.

I guess I will initialize it and start over. But 1in 17out definitely didn't work. You're saying make it 17in 1out??

Wait... just thought of something. I think I installed it wrong lol cause the maf wire was flipped now that I think about it. Wowwwwwww I I bet that's what was wrong the whole time. I JUST thought of that. I'm an idiot.

 

If you're an idiot, then I'm an idiot. Did the same thing when I installed mine ..

After the reinstall, don't reverse the settings, leave them as is, 1in 17 out.

Practice makes perfect
