Hi,

I'm going to turbo my VR6 2.8 AUE 24v so I am doing a research about our lovely me7 ecu for N/A. There seems to be a 100% load limit (called hard limit in some topics). Some people say that the limit can be raised by tweaking limiters. Is that true? Have not much experience with NA me7, but I have done some 1.8t for 400-500bhp. I know It can be bypassed by underscaling maf (I really hate to do that and want to avoid it). I'm searching these limiters in R32 damos I've found somewhere here and the only thing that seemed to be interesting (except KFMIOP/MIRL ofc) was MDIMX and MDNORM. What values should be changed except these?

yes there is a hardcap, find it in IDA or etc, there are a few of them , which means if you dont change them all, it wont let you start the car. Also MDMAX is completely different from 1.8t.

Thanks blazius, I think I found one, Could you confirm?


@edit for rl the factor is 0.75 so after conversion the load is 153.75 for rl, so is it the limit for rl? Also I found no call, jmpr or anything related to this function, seems to be interrupt.
