Rev Limiter Factor Motronic 1.3

[AlexG40]

Hello guys

I am looking the rev limiter factor for this old motronic 1.3 ecu.
I have tried all ready 912500/X but it makes no sense. Does anyone has any idea?
Just to help you rev limiter 1 is at 62c4 and number 2 is at 62F0Bmw 320i 1989 E30 0261200152-1267355487 ok.rar

Hello

Could be 6750000/X in 16 bit LOHI?
I think it is M1.1 ECU.

I think that it is wrong Vasily

It is quite easy multiply the rev limiter value (320 usually around 6500RPM) with F4h(244), you get 1586000 this is the scaling factor.
