A friend with a single turbo, M2 large SMIC, and upgraded radiator; runs Evans.
We live in Houston. Two weeks ago we were doing 3rd gear AFR runs and his water temps were from 90-92C. This was in about 90F air temps. He has his fans set to come on earlier than the stupid stock points that Mazda and the PFC use.
You need the datalogit to reset the fan set points, and the other WATER TEMP or AIR TEMP tables. Such ones affect fuel, timing, and oil injection.
The only WATER TEMP table accessable with the commander is the cold starting/warmup table.
Have owned my FD since June 1992.
