    Repeating Fault Code 75

    Unfortunately that log doesnt contain values for TP Error Accumulator or TP/Target Error Accumulator. If we cant fix it here, add these 2 into the logged parameters for next time so we have better info next time it faults. For now, we can see here that the accel pedal has no issues and rule that out - both main and sub track nicely together and show no AP errors Comparing TP main & Sub we see the 2 of them track together quite nicely so its unlikely to be a TPS error. These 2 values seem to be within 0.2 - 0.3 at all times which is fine. comparing e-throttle target against TP main & Sub postitions however, we see that every time you get off the throttle, the TPS postition almost "bounces" back up a couple %. Usually this is caused by PID setting issues in the ethrottle control. in your case it looks like they might be a bit too aggressive, and its causing some pretty bad overshoot (and for it to not quite oscillate, but still jump back in the wrong direction once it overshoots). This screenshot shows the worst example I could find of both the "bounce" when you go from full throttle to 0%, and for general poor tracking of target -> actual TPS angle. Note the blue TPS line overshooting by 10% ish repeatedly between 10:04 and 10:08. There is another good example at 13:40 +/- 5 seconds. I'd suggest setting your ethrottle to "always run", then with the engine off, tune your PID settings a bit while logging these same values, until you get TPS to track target reliably thorugh both slow and fast throttle transitions

    What is wrong with my tune?

    I just had a quick look. There is some pretty odd stuff in there. It looks like it has been tuned for flex fuel but there is only one ignition map and no other corrections for ethanol content. Usually E85 can take a heap more advance than petrol so what fuel was that ignition table tuned for? VVT looks like the offsets are set incorrectly. The RH inlet cam is showing 10deg advance when it is in the fully home position. That means it will be getting 10Deg less than what is commanded. The VVT and ignition tables both have big "holes" in them around the cruise area that is going to make it drive pretty horrible. Boost control not working great at all. Fuel control is not great either. I would say this is due to there only being 1 VE table set up, which doesnt usually cover flex fuel well enough especially when injectors havent been flow tested on both fuels. I think the saving grace is you are running it on relatively high eth %, which is relatively forgiving. I wouldnt give it a hard time especially on petrol until it is looked at by someone more competent or interested. If you want to PM me the tuners name I will pass it on to the right people to consider.
