And what's looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. This is your new Accessport.

*91 Oct = 95 RON | 93 Oct = 98 RON. Peak gains are measured as the difference between the highest points of the two plots. *Largest gains are measured as the largest gain at any single point between the two plots. Results may vary.
Generally speaking, 91 octane calibrations have a richer fuel curve, and a less aggressive ignition advance map to help compensate for lower octane fuel blends such as those found in Arizona, California, and Nevada; and/or less than ideal atmospheric conditions. The maps designed for 93 octane are the most aggressive. *91 and 93 octane results are compared against a 93 octane fuel baseline. Your 91 octane results may be higher than listed above; as a baseline of 91 octane fuel may read lower than our 93 octane baseline. 87 octane results compared against an 87 octane fuel baseline. Your 87 octane results may be higher than listed above if a blend of higher octane fuel is present.
