    E78 to E38 swap pondering

    I'm happy with the way my turbo 6.0 is running on my E78 but only on open loop and I'm kinda thinking the ease and consistency of closed loop maybe worth the hassle of repinning for the E38. Closed...

    There is some real good detailed threads on what you are looking for if you search.

    Tip: make a trans tune that will hold gears way down in the rpms and manually shift it. Get it into 3rd or 4th...

    I got pissed at tuning the VVE on mine with VVT so currently the cam advance tables are zeroed out... Maybe after I get my cold piping redone and MAF put back in I'll do it.

    It takes a while to get the tune setup to compensate for temp changes but you can scale the VVE tables/MAF and use Airflow Gain to do your boost enrichment by MAP and activate your PE with requested...

    Step one for you is tune your maf/vve.


    E78 isn't too much harder than the E38 on the V8 platform imo, I've done a bunch of both and I'm running my turbo 6.0l on the E78. Just a bummer there's...

    Did you tune the maf/vve? If not, it'll really show up the flaws since the throttle can open farther faster and the O2s can't keep up/pe commanded doesn't match actual.

    Weird on that bias table. Knock threshold is under knock sensor tab and it has a separate table for each cylinder. Don't adjust that until you get your timing stuff figured out. You should...

    It's my "Airflow gain" table which is now effectively turned into my PE table, but only available in open loop. It's on my 6.0l V8 2015 Silverado.

    Here's how I have mine setup (OL E78 but same idea). Haven't hit a dyno with it but it runs and drives nice and smooth. I hit boost just over 1300RPM on 91oct

    You'll still want it to pull some timing or you will break things. The minimum spark table needs some cushion for knock events and shifts so don't set it to what your main timing tables are.

    Throw your book away.
    Leave factory TM settings.
    Adjust base minimum spark tables to stop it from pulling so much timing. Adjust other parameters to speed up shifts.
