Made my first EDC17C74.
But have problem from 2900 rpm that the torque drop down. (yellow in the mod log)
The torque in log does not match to the file from 2500rpm upwards.
Had a performance hole 2900-3000 and from 3700-3900.
Maybe i missed a torque limiter, but tried serveral changes but don`t find the problem.
Can give me anyone a hint, please

I know that i got only 60mg in this rpm`s but i don`t know why, will try your options.
In my log is log from ori and from mod, there are two tables.
Do you have a look in the mod table ?

3c02aa i´m not sure but i think its correct adress
Bought a damos now, but does not match in this area 100%
But 3c02aa is x-axis (rpm) in AccMon_tiShOffOvrRun_CUR
I think AccMon_trqMaxEng_C is on adress 3C02BA or 3C02BC
