hey! does anyone know what can be the problem? Car is m54b25 e46 2000 year. Changes what we have done with stock ecu is that we deleted dsc abs softwares and changed fuel map, and they should be alright. it sounds like rev limiter and it is stuck at 3500rpm like "limp mode", car doesn't give any codes exept tacho signal unplausible at 3100-3200rpm. my guess is that it can be crankshaft sensor if it is loose but then the sound would be random cutting? and i'm using inpa. https://www.youtube.com/watch?v=S5BqQw9HuKc here is link how the car is acting. sometimes it works perfectly.
Is the ABS/DSC completely removed from car?
Does the car know vehicle speed?

Can't imagine why anyone would delete ABS. How is the engine computer getting the vehicle speed?
Personally, I'd say it's time to undo whatever ABS delete you did in the DME.
