I posted the logs elsewhere, but here are two logs done on the same track:
N55 Custom Cobb tune
PPK cooling tables (assumed to target lower coolant temps than stock)
88f and humid

N55 Stage 2+ MHD OTS map
Cooling (race mode)
86f and humid
http://datazap.me/u/banks334/lime-ro...ata=6-19-20-22
Lap times were between 1:08 and 1:10 at both events. Both tunes target around 200 load.
While the difference was not as much as I was hoping, there was definitely a noticeable improvement. Coolant temps ran hotter on the COBB tune and so did oil. This extra heat caused excessive timing corrections and load actual was therefore lower all around. The MHD OTS map with revised cooling tables was able to achieve greater loads while maintaining lower temperatures all around.
