hello forum,
new to the k swap game, I've been having issues with my ECU (possibly) not reading map sensor voltage.
set up:
k24a2
06 si transmission
ry wire harness
runnig on kpro v4
Back probing ecu connector A19 (map) reads 2.9v with ig on. swap map sensor with new one same issue, i can confirm that plumbing for map is correct and the car wont start with the sensor unplugged (so i know it reads something to turn on) i do not have another ecu to test or swap to try to replicate.
EK K swap ecu reads -29 psi

The vehicle must be running to correctly read the MAP sensor.

Re: EK K swap ecu reads -29 psi
Those are the values when vehicle is running, car runs leans
Re: EK K swap ecu reads -29 psi
Post the calibration and a datalog showing the issue.

sorry if i replied late i wasn't able to get access to my vehicle until today, correct me if i did not send it correctly but i believe i sent you my current calibration with a data log.

When running the engine pulls vacuum and this looks pretty normal.

Re: EK K swap ecu reads -29 psi
The a fuel ratios are normal? I thought I was reading a lean number around 10-11:1 and if I rev it cuts out and I do believe I have lean protection on (not sure if that the result of that )
Re: EK K swap ecu reads -29 psi
10 is rich and 20 is lean. I think you have it backwards
