UTEC and road course tuning

Mancini · 04-10-2005, 12:46 PM

I did a lapping day yesterday, first time with the UTEC and TBE on and I have a question about the 0% timing load site.

I had the timing in the 0% load site locked down from 4750-7250 to prevent shift knock. I noticed that my EGTs were skyrocketing to over 900C when maintaining light throttle accel during certain sections of the track...my thought was that it was the locked down timing causing this.

So, between sessions I edited the map and put the ECU in charge of timing in the 0 load sites. EGTs were fine but on a few sections I noticed I was getting shift knock when I lifted off throttle. So I'm kinda stuck between a rock and a hard place when it comes to the 0% column. Any suggestions?

Thanks,

Brian

you could try lowering your TPS crossover point if you have it set higher so that it goes into OLF and into the 10% column quicker. If necessary you could probably edit the timing in the 0% to be a slightly higher value closer to what the ECU would want to run... just my 0.02

You could try adding fuel above 5000rpm.
