Default Edit v1.3 users, or those in the know???

Ok, I am trying to work a few things out and had a quesiton on the PE table. If the PE table in v1.3 only uses kpa as a measure, then if my MAP to enable was at 15 and MAP Hysteresis was a 5, I would be in PE mode pretty much all the time correct? Assuming at idle I am at 9.3psi * 6.9= 64.17kpa. WTF?

I hope this is not right, or actually I hope it is, then it would answer some other quesitons about my car running the way it is.

TIA,
Charlie.

ok, it must be in psi. I looked at a dozen other tunes, from factory stock to modded all had the same value, 15 & 5. Only value change was one of the tunes had enable rpm at 3200.

MAP to enable is the minimum Kpa you must have to "enable" PE ... if you don't have at least that much the PCM will not enter PE mode

that would make sense as well.. Good to know it is ok at that setting, bad because it solves nothing for me tuning wise.
Thanks,
Charlie.

When goofin around I came to the conclusion that the MAP Enable is how much the MAP needs to change in Kpa before initiating PE.
