If the controller had a built in MAP sensor you coudl use that to determin load. Similar to the MegaSquirt controllers.

The factory used cold temp tables to keep people from abusing the transmission, you should be able to omit that with a warning to the user that he/she should let it warm up before getting on it.

It would be very nice to have a tow-haul mode (or 4-LO) that'd use an alternate table to keep the RPMs up longer.
