MPI Woes

[StorableComa]

11 BAR is waaaay to high anyhow. Aftermarket MPI injectors are generally rated only up to 5-7 BAR pressure

But, that would be the MPI sensor / lpfp pressure.

As someone who is unusually averse to/afraid of doing MPI to a car I semi-daily, I'm subscribed to this thread, and eagerly await the outcome.

Also...supporting my Texas neighbors.

Hope you get it sorted out, B.

Not to sound like a Jerk, but you need to post your setup otherwise it's just a guessing game.

Did you happen to flash an older file without the low rail pressure sensor enabled?

 

[scrllock]

Can you dump your CSV that you're using to log with? Are there any problems besides what ST is reading for low pressure? Could be the conversion or PID are incorrect.

Totally confused here as I am about to do MPI on my car and shop tells me my mpi harness pins into OEM ECU harness? What the hell am I missing here? Check your pinout locations and go from there.

I'm confused too... I've gone over the pin out numerous times. I've talked with others smarter than me. if you're about to, you should be good. If you're worried about it, I'm an expert on it now, come up to central texas lol.
