I'm not sure I understand the question here. The table basically describes points in a 3D square surface. One edge of the square is set at all-3800, but the rest curves off smoothly. Just setting 3800's in the last column isn't sufficient, and neither are any of UpRev's built-in simplistic smoothing models.

Keep in mind all I've done here is experiment on my own car. I don't have other cars to compare with, test on, or look at the stock maps on, so this is mostly for people with a Tuner license who are also willing to experiment.

If you're going to have a 3rd-party tuner try to play with the throttle map from my first post, I'd advise you have them read the whole thing and compare your stock map to the stock map I posted at the bottom of that first post.

I'M going to see mg tuner at 12 and wanTed to see where mine where set. I'm also going to set the fan speeds to low @185 med @200 and high@215. Is that right. thanx man.
I haven't had time to fully explore the fan speed option. I'm not 100% sure how it operates relative to the table until I test it (whether the ECU interpolates between the low-temp column and the next one up, or if they're just switching points, that's my biggest concern).

In general though, the ideal for the fans for me would be: 1) Ignore whether the AC is on or off, 2) Keep the fans off at low coolant temps, 3) Turn them on full blast and leave them on, starting at about 185.

Well, there's also the speed thing. It might make sense to turn them down/off at high speed when the car gets plenty of air on its own. I'm really not sure about this point. I could see useful arguments in either direction. Maybe having them spinning at speed still helps channel more of the incoming air in the right direction (into the radiator instead of around it). Then again maybe it doesn't change anything for the radiator and just adds turbulence, or worse maybe it actually slows down the incoming air to have them on. I have no clue about this stuff, and not sure yet how I'll get data.
