I will read over your thread tomorrow, and see what I can learn about it. Sorry about being a noob with this part of the tuning, but I don't really understand what you mean by this:
"You may need to decrease your PW adder% vs TPSdot curve after doing it."
This is because if you lengthen the Accel PW time, then, maybe alot of fuel will be injected for a longer time. Now, you've tuned it so that a big PW spike happen on accel. I'm suggesting you to reduce the amplitude of the spike (by decreasing the PW adder % vs TPSdot curve in the Accel Wizard) and increasing the lenght of the spike. Then, the same amount of fuel will be injected, but in a less spiky way.
But, this is if you want to use AE only. If you use EAE, turn-off traditionnal AE by setting the MAPdot and TPSdot thresholds very high. It will be easier to tune EAE.
For the distance of the O2 sensor, I would like to see where this downpipe is located from the cylinder head (long turbo manifold runner?).
