he is an idiot. i had 3 versions of the tcu mod. ecu rev limiter from 6200 to 7000 tcu limiter from 5800 to 6900. none of them worked. i spent 6 months sending dozens of loggs from 2 to 4 gear from 1 to 5 gear pulls and everything in between.if you do the research you will see the only people who love the tcu mod dont do any datalogging at all. simple data logg shows massive high afr spikes during the shifts.
in the end i went back to a stock tcu and e/c gave up on trying to fix it for me.
