I am still looking for someone in the chicago area that can code out nannies if anyone knows a guy/girl that can do it.
I'm going to do mine before I hit the track in two weeks. More than willing to help you out if you would like. You would have to make a small trip to Milwaukee though.

I love that town! I'll hit up the brass rooster while I'm there! I'll send you a PM.

Is anyone running an upgraded oil cooler? From my research and same issues running at Njmp Lightning/thunderbolt its all from high oil Temps and running in a higher gear and shifting at 5500 resolves the issue. Very annoying bc you can't derive the full potential of the car drives me nuts. I haven't run logs yet but once past 250 is where issues occur, shutting down on track is not ideal

I would have to double check the oem binary but the ecu doesn't start doing anything about oil temps until way way past 250*C. I think it's around 280-290 IIRC.

You are prob right, unfortunately I can't operate my obd reader and record oil temps. :

My assumption based on I was able to shut the car down mid session on lighting bc oil Temps were def above 250, but I never took time see how high it went, too focused on driving like a mad man for no reason.

Not that there is any black magic going on but y'all should see how the F8x S55 cooling system works. One traditional water pump, driven by its OWN separate accessory belt. One electric water pump, that is manipulated via driving mode on top of driving behavior. Their oil cooler is also like 3x the size of ours. Track oil temps on their cars literally get to 210F and go nowhere, apparently.

With the redundancy going on there I'd believe there's an aerospace engineer at BMW M except they put the oil cooler under the radiator and is often punctured.

Anyone closer to results with a big OC and modified cooling tables?
