What tuning parameter are you looking for this to control? Also, just curious, what EFI setup are you using? On our 356 EFI build we’re using an oil temp sensor, both for warmup and for a tiny bit for over temp protection. Because of the time it takes the mass of a cylinder head to heatsoak, and thus change temperature, I don’t think that you will gain much by pulling boost or dumping more fuel once the head is overheating. (FWIW, I don’t think using oil temp is a good medium to use either for overheat protection, but better than nothing, and I can trigger a dash light with it). I think you’d be fine if using this for the warmup cycle, but then why not just use oil temp for this?
