    Default E92 tuning tutorial?

    Is there one available? Not finding one in search. Target vehicle is a 2015 Tahoe 5.3L. Thanks.

    E92 is like E38 except that you have to calculate/log MAP:BARO ratio to reference the axis on some tables.

    Thanks. I'll look over what I found on the E38 and will post any questions I might have. Currently down to one vehicle right now so I'm not willing to make changes at the moment, so I have plenty of time on it.

    Let me know if you need a calc_pids.txt for E92.

    I think I'm ready for this now. What calc_pids would I need for this? Also, any direction in improving throttle response would be great. It's a bit of a dog off the line under normal acceleration, and if you add more to compensate it goes way too far. The throttle doesn't act linear at all.

    E92 is not like E38. E92 is ALOT different to tune vs E38, it logs he same sorta but thats about it.

    Doesn't E92 have MAF tables and VVE tables that are tuned in the same manner as E38...

    Yes E92 has MAF and VVE that are the same, but thats about where the similarity's stop. E92 has a lot of different tables and uses torque and torque calculation alot more vs E38. E92 has a steep learning curve.

    Yes, I agree, after tuning MAF/VVE then it becomes a steep learning curve.

    I'm down to contribute for a modeling tutorial.

    I have theories that I've tried and seem to work. But it would be nice to have some absolute's.

    I don't know EVERYTHING there is and I'm constantly learning something new and trying out new things to get results. And I've gotten a LOT of good help and information on this forum. I don't mind giving back.
