Hi, I have a link g4 extreme installed in a jzx90 Cresta with 2JZ. To get the car running i used the supra plug in base map and wiering is pritty much the same as for the supra plug in though i am only using MAP sensor. And then I went to my tuner, everything was going pritty well untill we encountered what we belived was missfires at 6700rpm. We tried different coils, closing the spark gapp on the spark plugs with no result at all. It seems to be unable to rev more then 6700 regardless of temperature, load or anything. Even reving it standing still with no gear can't get past 6700. The stop is very rev-limiter-like and always the same.
We tried disabling all limits in the link ecu, logs show no limiter has been hit and no fault codes.
Can this be caused by me using the supra plug in base map on an extreme ecu? Can this be caused by bad cam or crank sensor signal without it logging any faults?
Do anyone have any ideas?
