Went to the dyno today to test ignition advance settings with E85.
I noticed it was pulling 2.5 to 4 degrees above 6300 rpm. Don't pay too much attention to the timing map as I was adding to it just as a test. I looked at all the modifiers and I haven't found the reason why it would be pulling timing. On the attached log and .hpt file I removed the the torque management for the 3-4 shift and added to the 1.2g row, copied the low table to the high table as my last test. This was the the least timing it pulled out of the 4 test hits we made. Is there something in the Gen 3 PO1 PCM working in the back round that HPT doesn't give us access to that may be causing this or did I just over look a modifier somewhere?
Is there a torque management issue that may be causing it?
I gave up for the day when the blower belt started slipping in excess and realized I couldn't find the answer to why it was pulling timing. Any and all help is appreciated.
