What oil temp sensor do you use for EFI?

When I first installed mine that came with Bitzracing's kit, it looks like a thermocoupler that is installed onto the engine block, but I think there gotta be a better (more accurate) solution that can, for example, measure oil temp?

Oops... meant to say Engine or Coolant temp sensor in the title

If you do warmup enrichment from oil, you'll be pig rich for a long time as oil lags head temp greatly

Good point... so you use CHT type sensor as well?

I have a 3.2, so it already has the Motronic CHT in cylinder #3 already.

Yes, I use it for WU.

Plus that fun dip in temperature again as the thermostat opens up.

Oil temp is nearly useless an engine temperature input to an EFI system. Convert to cylinder head temperature, enjoy having a single warm-up cycle.

Exactly!

When I was 1st learning to tune, I saw head temp went 300+ degrees on a 100+ degree day. I thought my warmup slope had to stop there! It was running in warmup mode forever making tuning painful until I learned OEM stopped around 150?
