Furthermore I opted the setting on my racechip to F/4 to boost fuel delivery while maintaining full monitoring of catalytic temp, oil temp, kpa/bar on turbo, dpf temp and other related settings, there was no abnormal numbers and the car works fine and are even a little bit stronger in higher speed and yesterday.
I’m probably going to set the highest setting on both S1 and S2 that is possible in the near couple of days to see how it works. In regards of the risk of overheating the catalytic converter i think that is impossible whit a piggyback tune, i used to run my e92 m3 whit stock exhaust and the ESS supercharger kit 575 hp on the car whit 600+ hp total and never had one little problem whit the catalytic overheated.
So the setting I’m going to test out is 9/9 on the chip but i doubt the car is going to turn into an aventador but maybe some minor gains can still be possible  |
Works within the tolerance of the car - until it throws a code.
Anyway, it would deb interesting if you could at least provide 0-60 times when comparing. That would really be helpful in truly measuring gains as you dial up the chip.
Also, how are you measuring catalytic temps? And what is DPF temp? Just curious as I don't think I've ever heard of this one.
Knowing the cat temp is good as you probably won't damage the cat itself, but the cat temp will give you an indication of EGT your engine is producing and this is VERY important. Piggy back chips are usually the worst offenders in creating high cylinder pressures which means high EGTs, which damage diesel engines quickly.
And shame on RC for not monitoring the forums anyway. Helpful posts would really pay dividends in sales, I'm sure.
