    I never got around to looking into the issue the project got put on hold , I think it was a ECM issue or the tune file was corrupt because commanded timing kept going to 60 degrees.

    Now I have a different project going was wondering if somebody still provides a service to have the tcc locked at 0% tps and also have the ability to hold first gear in manual low and not upshift to 2nd . Would be willing to pay a small fee as well just want to get it sorted . Its a 2000 ECM with 512 kb memory . It just sucks efilive doesn't do anything about it since both features are available on HP tuners. Thanks
