500hp 635tq lean above 3500.hpt497hp 638 tq leans out up top.hpl


Car is strapped on the dyno, everything in lower rpm seems fine Just cannot get it past the brickwall at 3000rpm and higher. Any insight is greatly appreciated.

STFT stops responding as soon as the fuel source is changed to the power enrichment and then starts responding again when the source is changed back to the Stoich.

I would have check how the fuel pressure is being changed between 2000-4000 RPMs and also if the injector data is programmed correctly.

Something strange is going on with the maf reading. You need to log Maf voltage. And the fact that the air load pegs at 2.0 the whole run.

I would look at supercharger pressure, looks like Max supercharger pressure is set to 36.84 approx 2bar, the MAF is only hitting 77#/min so not maxing . the air load is 2.0, on these older gt500 i like to see pressure drop across the fuel injector and fuel pump duty cycle. Also we usually set MIN and MAX baro to 27.00 on boosted car the BP will not be correct setting to 27 prevents false learning. change your MAX rpm for SIP test to 1200. set max count for supercharger inlet pressure to 1023, set RPM for MAF to Fail to 7000, make sure your Aircharge WOT multiplier1.899 and correction for MAX aircharge is set to 1.899, last Supercharger Max pressure set to 55 inhg i think 75 is to high.
