This thing idles and runs great until I try to go to redline, it just falls off and kinda sputters at around 5500 rpms. Every where else in the powerband below say 5500, it drives perfectly, nice clean acceleration.
Wideband says I am going crazy rich like high 7's to low 8's at WOT. Acceleration is smooth and clean until about 5500 to 6000. Haven't gone past there because don't want to eff it up.
Stock twins, stock boost ~11 lbs, RC Eng. flowed the side feed 440's (the non resistor pack ones), fresh NGK BKR7E plugs gapped to .28, SARD ecu. Fuel pressure on Aeromotive is at ~37 lbs at idle with vacuum plugged in and rises fine with boost. AFC NEO is zeroed out across the board--all 16 rpm points. Swapped in my spare 1j map sensor with no change.
What I don't understand is that when the wideband says it is way rich, I'm not really seeing that much smoke if any from tailpipe, when my 7m ran rich the back of my car would surely indicate this condition as well as the rear view mirror.
The next thing is that when I pull the plugs out for inspection, they are still almost white, not quite the nice tan color but not all the way white either. I don't know If my wideband is lying to me are what, but the afr's at idle are right there where they are supposed to be.
I get no codes, haven't used any oil which still looks new after almost 750 miles, twins don't smoke, on start up or on decel.
On the 7m, it would run way rich, smoke fuel out the back but would always pull to past redline with out breaking up like my 1j.
Is it possible to be running that rich at WOT with plugs not indicating it, also without the trademark cloud of black smoke?
Could it be pulling the timing or am I barking up the wrong tree?
Any thoughts however insignificant you think they me be would be appreciated.
I feel like I may have just missed something simple in my swap keeping me from my much deserved bliss of the 7000+ redline from my SARD ecu.
Thanks
Wayne
