    Torqhead 3 bar OS

    All,

    I've written the new 3 Bar OS into the Torqhead PCM. Followed procedure to the letter, even the time between steps.. I cannot, however, see the new OS description when I open the OS window. It's blank..

    The Torqhead PCM specs are:

    2002 Pontiac Firebird Formula/Trans AM, 5.7 L, 8 Cyl, GM_P01, 2G2FV22GX22000000

    When I open up the scanner, there is no MAF PID to delete..., guess not worried here since this is SD only, so maybe it's already deleted. I deleted MAP (SAE) and inserted the MAP-3Bar PID, no issue there.

    Saved config..

    Just not comfortable that I can't see the OS now when I open the OS window..

    Have already set up most of the initial tune and it's in the PCM (VE, Spark, Injectors). Still have more to take care of before first fire..

    I'm using MPVI 2 - PRO, so will need to pipe in AFR from external WB (not done yet)

    Am I worried about nothing regarding the OS window not showing anything?

    When you move to a Custom operating system you will no longer find it in the OS tab as there will be no other OS options.

    It will be under Tune Details next to the close file folder.

    The OS tab goes blank on Gen3 PCM's when a custom OS is applied. With the editor open hit keys "Ctrl-D" and the calibration details will come up. The Controllers tab will show you the OS of the calibration.
