94 Octane

MHD Timing Correction Logs

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.
