Did you edit the MAP scaler for the 2-bar MAP sensor...?

Hi Joecar. The MAP scaler is done too. Out of curiosity we logged current gear when doing a power run. We noticed knock at the exact time the gearbox downshifted from 2nd to 1st when first applying power. The next few runs we held first then applied power with no knock. Whats the odds the shift change is giving us false knock?
Well, the last time I did a run that went into boost, I simply put it in fourth gear and just ran up the RPMs. At 69% throttle at 1751 rpm I was already at 105kPa. I was at 182kPa at 3700 rpm when the wastegates said "enough!". My log file is on this page -> http://forum.efilive.com/showthread....-please/page14, post #135. Boost starts around frame 11920.
So I'm hoping I'm OK in that department.

Thanks again spider.
So far we have completed the main VE and the BEN factor is great. The boost VE we have adjusted so that our AFR is where we want it under boost. We still cant get the PE working unless it is in closed loop. So the BEN factor when in boost is way off but our end result is good. If we put the tune back to closed loop and disable the PE how will the AFR react when in boost. Seeing the engine is a lot richer than the commanded AFR will the PCM lean out our tune under boost? If so how much could we expect the tune to lean out during a power run?
