Re: Attn. All Data Loggers

Very interesting spreadsheet...I have a few questions.

I notice in the chart "0-60" that the mass air flow dips hard right off of idle, and again it softens around 2500 rpm, and finally falls off at 5000 rpm. With the rpm on the rise, and I assume the accel pedal is WOT, the only thing that I can think of that would cause those air flow dips would be actual throttle being pulled back. Could you (or have you) rans those same runs while logging both accel pedal position and throttle opening?

It's easy to see how much ign timing is pulled back off of idle and during the shifts..

Thanks!
