Yes Stu,on Oli's car it was on boost at 2 bar held. With the engine right at its limit at 12.5:1 AFR we were hitting 1000DegC ex temps, and richening to 11.0:1 at this boost level brought it down to near 800. (Pretty much what you'd expect on an engine thats being pushed this hard....i.e. having to overfuel to keep temps acceptable)

Steve the above situation has nothing to do with Stu's lambda controlled maps. These maps only run at lambda 1 at very light throttle and below say 4000rpm. Everywhere else it returns to the base map.

Next time I talk to you I'll tell you about the nightmare TFC problems I have with greys on non lambda maps ESPECIALLY on L6 managed cars.
