PE Enable: Mode Delay RPM, Insight?
My Mode delay is set at 5000rpm. Am I understanding this correctly, is this the rpm that PE starts at wot? I have set it at 3000rpm accroding to my current launch rpm of 3500rpm on the spray. I want to make sure PE is enabled at this rpm. Anyone have experiance/knowledge/insight on this issue? Thanks in advance.

well i know in my cal file it has the pe delay rpm which is set at 3500. But on top of that it has a timed delay depending on throttle position and then it has a pe delay bypass which is a set throttle position. So from what i get is even if the delay is set at 3500rpm but the bypass is set at 90% throttle the moment you go over 90% throttle it will be in PE anyways without a delay

I don't think setting your PE Mode Delay to 3500 will hurt street driving.

405HP_Z06, I looked and mine is also a default of 5500rpm, my bad.
rcfast, No PE delay bypass, that I can't find.
Gameover, Can you ellaborate on your statement. It doesn't make sense to me. Are you saying that PE should be disabled while making calibrations or it is disabled while calibrating. Or, is it something else? Some say disable pe while tuning LTFT and some say no and only go to 4000rpm, but I think if you don't go wot it's out of the picuture anyway?

the editor is missing the actual PE Delay value (we plan to add it), however, on cars PE Delay is always set to 0, it is only very rarely used on some trucks.

Some disable PE mode by tuning, but I see no reason to do so. Just make a conscious effort to NOT hit the throttle postion/RPM to put you in PE mode while SD tuning with fuel trims. Fuel triming is disabled in PE mode so that is true.

For some reason, my trims are not locking at zero during WOT. This only started happening after I tried leaning out the PE table. I know it's not the OLFA table because its divisor is at 1.13 and my PE table is at 1.15. Still trying to figure this one out...

My PE fuel enrich x rpm is 1.203 at 800rpm, and TPS is 45*at 800rpm. Does this mean that at 3/4 throttle PE is enabled at 800rpm x 1.203 multiplier? So, you don't have to be wot to enable PE? A little confused, but just making sure what/why I am doing a step.

Ok, I am at the wrong table, will check.
I found, Hot Power Enrich Enable %TPS x RPM. Now, at 800rpm TPS says 45%. Does this mean at 45% throttle PE is enabled at above multiplier? If so it gets progressively easyer to turn PE on. Isn't this going to throw my LTFT off? So, PE does not have to be wot to activate?

This divisor can be overridden though if you switch into Open Loop mode. If this occurs (like at WOT), the richer value of the PE Enrichment V8 Mult vs. RPM table or the Open Loop F/A vs. ECT vs. MAP table will be used.
