Car feels more powerful. For science sake i added 3 Liters of bio ethanol to 1/2 fuel tank. This makes it around 10% ethanol. The timing correction that was there on the 98ron log was completely gone once i added the ethanol. For some reason cylinder 5 always keeps pulling timing. I don't know why. It did misfire 2 times on cylinder 6. I cleared the codes and went on, the misfires did not return. This was after i added 3L ethanol to half a tank. I managed to do a 7.9s 100-200. This was with 10% ethanol.
