Hi. I am working on my ECU simulator but cannot find any info on how to calculate a value to send for PID 0x87 Intake manifold absolute pressure.
Sounds like a school project that was pushed off for a few weeks. Start by posting a proposed schematic, not a frizzy thing showing your circuit, include all power, ground and interconnections as well as power supplies. Post links that show the technical data on each of your hardware items. I have no clue what eCU you are using, there are over a thousand different designs that are still in operation. You can always add a MAP sensor that you can get all the pertinent data on.
Looks like this forum is full of idiots like you. OBD2 PIDs show a list of values and many have a formula. This one doesn't explain it. Was hoping someone here might actually be helpful instead of rude. Time to leave. You have no need for circuit details either.
