I'm reading/logging the MAP voltage with my LM-1 WBO2 unit. I would like to know if some mapping exist of the MAP voltage to the KPA values shown in Tunercat. This is for a TPI engine. TIA.

If you made it this far, you have no excuse not to have a factory manual.

They are invaluable for troubleshooting and thourough explanations.

They even have a MAP to volts chart in them.

It has been posted here multiple times.

Do some searching and get a factory manual(or equivelant source)

later

Factory manual. Ok. I do have one but for a MPFI V6. Same thing less 2 cylinders. I'll look there then and see what can I find. I just thought this was so common here to be in a web page somewhere. Tks.

It is here, sometimes you have to break down and search. It helps.

It doesnt matter if it has 2-4-6-8-10 cylinders, the map to kpa is the same on the 6 and the 8.
