ok guys i need help. We have a 2011 sierra 2500hd 6.0 a6 with a whipple charger and headers. I cannot figure out the fuel stretegy on this e78 controller. If you look at the log file...watch the wot pull at 40seconfs into the log. a/f is good until about 4800rpm. Up until this point commanded a/f is 11.7 and then it leaans out to a commanded a/f of 14.6. wtf what is causing this? I need some direction on the fuel strategy on this over complicated unit haha. Thanks
First set your power enrichment enable torque to 0 at all RPM's. If still no PE, then 0 the RPM Limit Accel Thresh vs Accel table. Also max out the Piston Protection enable RPM as it can add unwanted fuel .
