....mmmh.....
I am experiencing in Issues with ARC....
I have 1EL5B ECU.
Sometimes with ESP ON in normal driving (I think that with ESP ON ARC is disabled), on WOT, third or fourth gear on, clutch engaged (in other word in a full acceleration to REV limit):
The ECU cuts power at xyz RPM (like when ARC is in Launch Mode with Clutch pressed, ESP OFF and first gear on) !!!!
I must leave the gas.....
I wrote to UpREV one week ago, but not reply....
My ARC settings are the defaults on a blank ROM.
