Cross8 4wd

[johnv]

Anyone tryed tuning a Cross8 4wd?.(05 fly by wire)
Had a play with a mates today , even with the std spark tables and 98 octane fuel we were getting 5 deg knock retard:bash: .

These things have fulltime traction control (can't be turned off) tryed to disable it but no luck:nixweiss: must be something we can't see in the cal that prevents removal.
so so slugish off the line and can't even spin the wheels trying to do doghnuts on a sandy beach:help2:

Any ideas !

Would anyone have a tune file for the HSV Coupe 4 or HSV Cross 8 tocompare ?

Cheers

John,

The traction system is primarily done by the ABS system in these 4WD's, plus some PCM control..........even with a blower..they aren't too exciting so a bit more timing isn't going to fix the problem. Real 4WD's have a Duramax Diesel badge on them, 1000ft-lb of torque, I've been converted.

Cheers,
Ross

Ross,

WOT fueling was quite rich, sorted that out but couldn't get anymore timing into it:bash:

As far as I could tell I disabled traction control and torque management, abuse mode etc.
But even on sand WOT doing 360s it wouldn't alow any more then 2500 rpm and no wheelspin - thought I may have missed something:nixweiss:
