[Magic Solution]

Hello :peaceful:, writing regarding my MB W203. I swapped 5.0 V8 M113 from SL500 R230, added manual transmission and using it for drift. There's no catalyst converter anymore.


Soft requests, please 3 versions:
1st:
* disable rear lambdas (current fault codes: P0141, P0161, P0140, P0160)

2nd:
* 1st + following:
* improve rev limiter - to be more like BMWs - hard fast cut (as at the moment it strangely cuts around 6000rpm and then goes around 6300rpm and then it is really "slow" like playing with the gas pedal)
* increase rev limiter (if possible and safe, will give me more wider area as sometimes 2nd gear not enough and 3rd too "low" for drift tracks)
* increase rev limiter in neutral (currently around 4000-4500rpm)

3rd:
* 1st + 2nd + following:
* pops and bangs
* more power if possible smth from this NA


I prefer tested solution or who has experience with this ECU &/ engine and I'm willing to pay. Please send price to PM.


// regarding this original rev limiter:
