trying to get a good idea of where my PE settings need to be for launching at the track with a big stall.

heads and cam, 4000 stall. leaving off the line around 2500-3000 rpms.

any ideas?
PE Enable MAp: currently 15kpa
PE Delay RPM: currently 4000 rpm
PE Enable TPS: currently around 64%

have seen people set a higher MAp value and lower TPS value.
I'd assume you dont want to go into PE while sitting at the line brake stalling it up. I guess the RPM needs to be a little higher than the stalled rpm. whihc method should i do?

using HP tuners. thansk guys

 

If it were me, I'd want to be in PE stalled up. I wouldn't want to be sitting at 4000 at stoich building up heat.

 

Just zero out the PE Delay RPM so that PE mode is triggered by tps % only (anything above 64%) the other two are fine.

 

I thought that you didnt want to be in PE while you're not moving???

what is a good MAp and MAP HYST value if I run it like this? leave it low like 15kpa and 6kpa HYST. thanks

 

i see many people with stalls using 3200rpms as Enable rpm. why is this a popular number? I know people are running larger than 3200 stalls. is there some other significance?

 

because thats the stock setting in many fbody calibrations and is rarely changed because it won't affect your pe for the most part.

FWIW guys I've talked to Chris about it so we can make the definition a little clearer on the pe delay stuff, but for the most part the delay rpm has very little affect on things for the most part. IE many stock calibrations have it set to 5500 rpms...that doesnt mean you won't enter pe mode until 5500+ rpms...it just means that if PE hasnt already been engaged by 5500 rpms because of the delay timer(which isnt active in most applications) it will then activate PE mode.

For the record I usually just set the delay's to 0 & use the tps vs rpm as my activator.

 

thats what I'm gonna try doing. so you're zeroing yours out and what TPS % do you have it set? it's something like 64% stock up till a certain point, then it goes down to 55%, 45%, and something like 26% all the way to finish out the rpm scale. Thanks for the help
