Sorry, gotta throw down BS flag. Hard to say definitely with out raw data points such as data logging that shows how oil temperature effects the timing curve, or before/after data logs referencing timing, engine temp, IAT, etc...

I'm not saying its not possible, but from my experience (which includes using a full aftermarket ECU to tune a car), intake air temp (IAT) will alter your timing curve, not coolant/oil temp.

Temp inputs are used to warn the driver that things are not good. You would not want to pull just a bit of timing here...you want the driver to go 'woah!' Neo style: hence limp mode
