Previous software versions following the following conventions:
145C --> Limit before reduction of redline (for oil - 8,300 RPM)
146C --> 7800 RPM Limit (500 RPM reduction)
147C --> 7600 RPM Limit
148C --> 7400 RPM Limit
149C --> 7200 RPM Limit
150C --> 7000 RPM Limit
The Latest 240E software raises each one by 5C. Absolutely ridiculous if you ask me. In my performance software for NA cars, I reduce these temperatures slightly from the stock values. I think driving the car with 300 degree oil temperatures to 7000 and being allowed to do so from the factory is insanity.
Now for coolant temperatures we have RPM reduction as well:
115C --> Limit before coolant based RPM reduction occurs
116C --> 7800 RPM (500 RPM reduction)
117C --> 7600 RPM Limit
118C --> 7400 RPM Limit
119C --> 7200 RPM Limit
120C --> 7000 RPM Limit
I also reduce the temperatures in the code here as well. My software limits to 7K at 115C.
Finally there are reductions for gear oil temperature.
146C --> Threshold at which car will start pulling redline back
148C --> 8000RPM
150C --> 7500RPM
152C --> 7000RPM
154C --> 6500RPM
156C --> 6000RPM
158C --> 5500RPM
160C --> 5000RPM
I think all companies offering supercharger systems need to make these reductions more aggressive in their software calibrations. I believe in safety first. It's just not worth the risk and hassle. Better safe than sorry.
All numbers above are taken directly from the hex data in the code for the respective limits.
