Hi Steve,

I'm logging GM.ETCTP. I've found that using the "correction table" for PE control works fine. PE comes in as expected with no random changes etc, so I believe that the "correction table" works ( at least for PE ). I posted a pic of the table I use here....

The green line was logged data, 20 to 30 instances where the ECM entered PE for each setting of TPS%, then the values were averaged.

The Yellow line is just a trend line so I didn't have to log every possible setting.

As for the actual settings, I'm finding that setting TPS% quite low and only relying on MAP to control PE is working well.

Simon.
