Hi. I have a built 2.5cdb with je high comp pistons. Arrow rods . V6 heads with supertec full valvetrain. Ported and polished. Id1000 with paralel lines. Walboro255. Rotated gt35/82r etc.
I am trying to tune my Link G1-2 ecu. I just cannot past 6600rpm. I have the limeter set at 7500. I have no fuel issues. I replaced the crank sensor and cam sensor respectively with new ones, one at a time. Both times no difference in circumstanses. What could be my problem?
Thanx

 

whats the logger saying when you hit 6600 - is the wideband reading lean spots/no fuel or is the timing pulling back on you?

 

Do you have the correct amount of cylinders set up, know with my syvecs it had to be set to 4 cylinder it may think its hitting 7500 but actually 6600 and does the revs actually match what the ecu is seeing and not just whats on the clocks
