OBD 2 accuracy

A teachable moment, I had to look that up. Learn something new everyday.

Ford didnā€™t go that far with the Mustangā€¦ The models that display oil pressure do have senders.

But I do have and oil temperature gauge that is purely software as there is no temp sensor. I doubt it is correct given that I added ad oil coolerā€¦that the car doesnā€™t know aboutā€¦ so I donā€™t pay much attention to it.

If at a track day, I put the changeable gauge display to trans temp and then I have ā€œcoolant tempā€ gauge permanently on the cluster. If I data record off the OBD2 port, I record cylinder head temp, the software coolant temp, trans temp and the 0 or 1 oil pressure output just to make sure Iā€™m not starving it momentarily.

I still recall my surprise the first time I opened up the 427 in my '69 Corvette to find the trap door baffle in the oil pan. The design of the pan reservoir only goes so far. If youā€™re sticky enough and aggressive enough, momentary oil starvation is definitely something to watch out for. Great idea adding a monitor for that.

Thanks,

I spent money to find that little problem on previous cars! :money_mouth_face:

One was solved with an Accusump oil accumulator. The other with an Accusump AND a fancy $$$ oil pan with several swinging baffles!
