ls1edit PE "map to enable" I'm looking at the power enrichment menu and it has MAP to enable. Is the MAP pressure generally gonna be the same as what my vacuum/boost gauge shows? While running down the road im generally around 18" of vacuum. My "map to enable" setting is 15. Should I change this to something closer to 5? I'm thinking that it is going into Power enrichment mode with just a stab at the throttle to pass folks on the highway. I bet i got this all wrong but thats how we learn <img src="gr_stretch.gif" border="0">

Re: ls1edit PE "map to enable" I would really mess with the PE MAP table - that just basically sets the MAP parameters which have to be met for PE mode to enable.
I believe there is TPS to enable PE mode also - if you want your car to go into PE mode it would be better to adjust this.
Basically PE mode will disable learning (O2 based learning) and set your target a/f ratio to a richer value. You can adjust the target a/f ratio with the power enrichment table itself.
I really wouldn't worry about it too much though - adjust the PE table on a dyno/track itself, but unless you see/feel a specific need I would adjust the table you mentioned.

Re: ls1edit PE "map to enable" I agree with Chris, I wouldn't mess with it. 15 kPA is like 25" vacuum Hg - and it would be only one of the things that are required to enter PE. TPS would be the other.
This is just a switch for one of those items like EGR that relies on a couple of different conditions to be met before it's acted upon.
