The first log on April 2 was using the multi map flash I always use. I always fill using Petro Canada Ultra 94 and seemed to have no issues. I then ordered the B58TU HPFP and flashed to the 93 oct tune Stage 2+ HPFP. That log on April 7 shows alarming timing corrections in all cylinders. I’ve taken about 5 separate logs that all have an average of -10 degree timing in all cylinders on this tune even with correct fueling. Afterwards I switched back to my multi map tune (not attached) and noticed the same timing correction issues. My final log on April 8 is using the E40 HPFP tune after filling with 20L of 94 octane and 14L of E85. Timing corrections seem to have minimized almost entirely. Was fueling the issue all along? Are my spark plugs failing? Additional note: On the last tune (Stage 2+ HPFP E40), when flooring the accelerator in first gear, I receive drivetrain malfunction and 7 DME codes stating that all fuel injectors have been switched off due to misfires detected in all cylinders. I assume this may be due to the power produced at this tune however seems too dangerous to be normal on your OTS flash. Can this be avoided as well?
