Hello,
I am experiencing a really strange situation.
Bosch 82mm dbw with its dual inverted pots (main to analog 1 rising and secondary to analog 2 falling) and everything correctly wired.
E-pedal with dual pots (main to tps, rising, and secondary to analog 3 following the first)
Pedal position reads OK
Throttle position reads OK (if i move it by hand)
Dbw characteristic is OK (dc rising as tps rises).
The throttle DOES move when I press the pedal, but i CANT run the calibration tool as it fails saying that the plate doesnt move.
Fun fact is that if I press the pedal while calibration runs, it advances through the process
I tried disabling the second pot on the pedal and the throttle. Same result
I tested the hbridge outputs and with hbridge 1a the plate opens and with hbridge1b the plate closes.
If the ignition is ON and dbw is active but engine OFF, i can move the plate with my finger and it doesn’t “fight back”. However if i press the pedal outside “idle” then it does hold its position even if you apply force.
I have tuned many other dbw cars with no problem. I always use bosch 82mm. I even swapped the TB for another one with the same result
Check engine light is ON and says DBW error codes 512 / 516 but i cant find why
Firmware version was 2.168. Tried 2.175 with the same result
I even tested with another ecu! Same result
