What is it than?
The one that was not flashable through OBD?
How is fueling regulated in that ECU in that case?
Surrprised it wasn't the same logic as Me7.

M3.82/3.83/5.92.

Very different logic.

Intressting. Why would Bosch change their logic so much with Me7?
Can you shortly explain the logis behind the fueling in those older Motronics?

Because they got more advanced? Because the ECU can now store 1024kb, rather than 16? More sensors, more accuracy, more logic paths to follow.

Of course. That does not answer the logic behind how fueling is done on those.
Do they still have Lamfa, Bts, Lmkr and the logic behind as it is dobe in Me7?

From my little experience I think that M3xx/M5xx Motronic familiy uses a Load Based calculation for Fuel Injection / Ignition Timing / Load (Boost & Vaccum) and other functions. ME7xx instead uses a Torque Model calculation for same functions.
