The stock ECU for purposes of fuel/ign calcs only uses the temp sensor that's on the back of the waterpump housing. The sendors on the rear iron are for just for the gauges.

Datalogging the oil pressure and temp is always a good idea, a better idea is to datalog fuel pressure, that's some good info to have.

As for where to mount the sensors, I wouldn't drill into the Mocal t-stat though, I would get something like this if you're looking for pressure

For Temp, well I would get the same adapter on the front cover.... I always found it odd that people datalog the oil temp at the coldest location - after the oil coolers as it goes back into the engine - where the coolant temp is generally tapped is the hottest part, as it comes out of engine.... which is why I kinda want to probe both the front cover and the rear pedestal.... I'll probably end up welding a bung onto the front cover and tapping it that way if it doesn't interfere with the AC belts.
