Still not managed to raise the limiter on this. In the below (using the attached binary) you can see it soft limits at 7,300rpm like factory in neutral despite I believe the nmax parameters being raised (it does a better job of keeping to 7,300rpm in gear with lower rpm rate). 'TPS input voltage' (red) in the log is MAF voltage, TPS is logged over CAN and doesn't change at 7,3k rpm.
In the attached based on the a2l I have, I've raised all the relevant nmax values , tested lifting NMXALU and NHRSHB out of the way, set cwnmxgng to FF to see if it's some sort of gear-related limit (I've also tried 00, I have no idea of the bit config for this), and set vnmaxpnr to FF to see if that would force use of NMAXPNR (which I've raised).
No luck with any of it...
I've had a look at the binary posted in here:
http://nefariousmotorsports.com/forum/index.php?topic=13819.msg112369#msg112369 and it seems to be changing the same parameters for NMAX.
Any help/suggestions much appreciated!
