    PE delay

    On a number of truck 7.4 bins have a PE delay of 70 sec. Reading comments the tps AE is about a second and the map AE is another 2.5 seconds. What takes place between that time and the 70 seconds? I am assuming the 70 second delay is for a long high throttle hill situation to help cool the valves.

    I've always set the delay to 0, it's always woken up the cars when going to WOT.
    The man who says something is impossible, is usually interrupted by the man doing it.

    I have had mine as low as 3 sec and it didn't change much. I will try 0 and maybe that will help my lean pop on mid throttle tip in. If I really mash the throttle from a stop it is fine. Maybe that gets into the tps double delta area that I was wondering about in another thread.
