    I did some tests using the bin settings above. I can't find any problem with the PE display.

    I had looked at the adx file and it looked proper so I did not think you were going to find an issue there.

    JeepandGuns converted a 1227747 to 16197427 so I'm wondering if in the conversion pin out charts is an issue? In the beginning he had what seemed to be a lean bog on acceleration and shifting (Manual) that's how we got on that Throttle Kicker Topic. He found some big differences in Auto and Manual bin files in AE to fix it, so that led me to believe it was his bin. But he said he went back to stock chip and still did not see PE working in TP ADX... so... wondering if it is a wiring issue in the conversion?

    I had the same factory settings in my .bin when I set up the Camaro. You can set the delay to zero, or lower the Fast PE Threshold. I think I remember reading that it was done for better mileage, in the heavy duty applications which is what mostly came with the $0E, MotorHomes, Passenger Vans, etc.

    I don't see how the wiring could be an issue, but I certainly don't know everything.

    The problem is the bin, the stock settings are pathetic.

    I figured it wasn't the adx as I couldn't even feel PE kick in as I was driving the truck. I'll play around with PE entry settings,but need to get my ve tables dialed in first. It def would explain why my new engine has felt kinda sluggish.

    I will be busy sat morning, but I plan on tinkering with this sat afternoon. So its almost time to play...lol

    So in the meantime, in order to better understand whats going on here, and make better judgements about what needs to be done. Can someone explain in a little better detail the parameters for PE. Such as regular PE, and this "fast" PE your talking about. What is fast PE and what dictates its use over regular PE. Also, explain the delay. Whats its use and purpose? I understand what PE is (richens the mixture, and adds a little timing) But when and where it should come into play is the grey area.
    What would be the optimal settings for PE? Is it normally based on TPS or MAP, or both?
    Would the setting be something (simply for example, or conversational purposes) It would enter PE anytime the TPS is over 50%, and then the delay timer comes into play, so anytime its held over 50% tps for 5 seconds, it knows your wanting to burn rubber and goes into PE? And the delay timer is so its not constantly kicking it on if your say shifting gears and its only at that TPS % for a second or two?

    I don't really understand how it all works together well enough to explain, but your explanation seems to be about right. With my truck I took the simple rout and set the PE Delay to 0.0 and lowered the tables to 45% TPS. For a daily driver I'd probably set it to 65% or so.

    I've started looking at the code some to see if I can get a better understanding of how all these parameters fit together.
