I have some of this posted attached to a thread I started for SD Tune on the General Section. Hopefully I am not being a pain by posting here as well. I am thinking maybe some viewers in this section with similar experience.
I am tuning an 03 Z06 with a Magnuson that is overdriven to provide 10-12 lbs boost. The compression has been dropped a bit with 8cc dish pistons, a Comp blower cam has been installed, 2 Bar Map has been installed and scaled plus 60lb injectors have been installed and calibrated with injector.xls found elsewhere on this forum. I have installed CO3 and have done 1 pass at Steady State SD Tune at 85kPa and under. I went to do a sweep on my Dyno Dynamics and the motor will not rev past 3000RPM. It set codes P1514, C1221, C1222, C1248 and C1278. Also it set P0103 but I am having this set so I know that the MAF is off.
By maxing the top of C6101 I managed to have P1514 and C1278 not set but it still will not rev past 3000 as per the attached scan and tune files.
I did a test doing a sweep run while keep partial throttle to see if it was upper "power" level throwing the codes and it will successfully do a sweep as long as it is partial throttle at or just over atmospheric. As soon as you get some boost into it it throughs the codes and pulls the RPM back. It is hard to tell where the boost level is that causes this.
Next I scaled the VE Table, Boost VE Table and Injector Table by -20%. This allowed the engine to now RPM to 3800RPM.
What am I missing? I am hesitant to scale the VE and Injector tables further.
Thanks
My apologies for being redundant here and a being pain in the tail.
