Tuning AF and timing with tweecer.

[WhiteDevil]

Well I just got my wideband installed.
Also my car goes very lean when I'm at like 3k and just letting the motor brake the car. Is this normal? I just read your info on the spike on acceleration quick, I'm wondering if it could be the same for letting the car speed down with just the motor.

Yeah mine goes from 20:1 to LEAN to AIR on my PLX when i down shift off long freeway off ramps. Fuel just cuts off. I know i was surprised too.

Also for WOT tuning my wideband is still stand alone so what i have done is have someone with me watch the wideband display while i hammer it. Then they tell me what were the numbers that they saw. I compare that to my commanded(Lambse) and make changes i as i go. 13:1ish seems to be the most common targeted N/A ratio.
