    V-Tech vs Power Commander

    Can some one point the difference on this two? I'm going to be running a big charger and I need to know which of this two is the best for my set up?

    You almost need both for ideal tuning

    Vtech is good because it actually has a map for full boost range so you get a fuel map that is close and timing for the full boost range.

    Power Commander is good because your fuel map can be auto tuned perfectly for your setup but if your running a stock ECU your timing will be not setup ideally.

    Depends how much you want to tinker, vtech will be closer out of the box with maybe only needing a rrfpr to dial your AFRs

    Power Comander is user adjustable, v-tech is not (you pick from pre determined maps).

    Also note that the Power Comander does not adjust ignition timing. I think they are working on a separate module for that.

    The V-tech is a complete computer re-flash......

    The Power Commander is used to dial in your AFRs,you will not be able to change your Rev limiter or timing curve with it..

    ^^^^^^^^^^

    Until they release the Rev extend module to hook to it. Then It will have the option to raise rev limit, and have +or -20deg timing adjustment...

    But I do not foresee it having the ability to remove the speed or boost limiter on the newer Bosch ECU's.

    The important thing to remember is the Powercommander is a fuel tuner and V-Tech a complete remap of the ECU which covers timing, fuel, speed limiters and rev limiter.

    So with the v tech and my rrfpr I should be ok to set my AFR? No other fuel tuner required right?

    Thanks

    People have been using a RRFPR to dial in their AFR for years with no issues, but if you want the absolute best in adjustability and auto tune then the Powercommander is nice to have.
    With a RRFPR you are basically just adjusting the WOT air fuel ratio. The Powercommander will get perfect AFR from bottom end to top end

    So with the power commander, is the rrfpr needed anymore?
