    Hello fast355,

    Thank you for your feedback, well, i had a lot of different issues while building my trucks engine and trying to tune it, first i had blackbox and 4R700 trans, it used to idle, but couldn't hold the load and the TB was wide open for it to idle. Than i changed to 4L60E, but some solenoids didn't work, because the wiring i had was chopped everywhere, but at that time i got the engine to idle at 675rpm when hot, it used to choke the first two three first times i try to start it, and had no cold start, but as i hold the pedal and worm it a bit, then try to let go and engine wants to stall, but i don`t let it and rev it a few times, than it starts to hold the idle, and i managed to set it at as low as 650-675rpm with this cam.

    At that time i used as a start point a calibration that i got from NISANDRA on this forum, i have just remembered that, will try today to use his calibration, may be a bit better. Where i got the .cal file i used last few times i don`t remember, i think its the 5.7 Express van 0411 file, but then i don`t remember where i got it from, because LEXTECH only uploaded .cal for EFILive tune soft, which is different format. Anyway, my point is that i have had the engine idling at really low rpm quite stable with my 08-467-8 Comp Cam. But now, after changing the wiring and getting everything on with no faults except the alternator L & F circuit fault, but that i guess is because my alternator does not have control by 0411, i couldn`t manage to reach the same idling result.

    Here is a .cal i got from NISANDRA, i guess i`ll try using this .cal file as a start point and will start it all over again from scrap today.

    Thank you for your feed back and open office excel file provided.
