Nice... If that's the case... Alto, EGT based enrichment would be nice....
Well, I did fry the 3rd piston... We don't know for sure the reason... I have a few guesses...
That day I did swap the injectors (300cc to 630cc) and just change injector setting in basic config... I did check EGO on all rpms at it looked fine (alto it's hard to look on those numbers when you are trying to control the beast on boost)...
I had a few problem before with a fuel pump setup... When fuel level in tank was below 1/4, on hard cornering and acceleration, I was left without fuel... But that didn't make any problems with motronic, just the power lost for a second... I was doing speed jump from 100km/h to 200km/h with just 1/4 gasoline in the tank, so maybe this was the reason for less fuel...
Maybe the engine was on it's end, so 0.7bar just pushed it to the death..
The boost was pretty mild, just 0.7bar (motronic stock is 0.6bar with 0.9bar overboost), but it's was constant in all the gear to 7000rpm... Motronic is knocking boost down in 5th and 6th gear to 0.4bar, and it is knocking power down above 5500rpm... VEMS was really hard torquing all the way to 7000rpm... C20LET was suppose to deal with 1.3bar on stock internals... Not just 0.7bar... But it seems that Motronic is hardly retarding the ignition above 6000rpm to prevent engine faster wearout...
The car was pulling really hard... Much harder then motronic on 0.6bar, and it fried the piston... But in those 2 days, Damn, I have smoked my friend with new S3 with miltech exhaust...
So it was worth it... :lol:
