Alright well I'm having a problem with the aem. Well, what I believe is a problem.


Car starts and idles but when adjusting fuel map it almost died, I pedaled the car to keep it alive and noticed that the car when reved says its seeing positive manifold pressure like around 8 psi.

Also the map sensor is seeing correct voltage, when he car is off its seeing 1.63 volts in the perameters section in the map sensor section.If the car stalls when idling the aem says its seeing 8 psi. Also the aem says its seeing negative 3psi but the boost controller says its seeing normal


Just didn't know if this is normal or is a legit problem.

Any help is appreciated.

 

Just go back and reselet your map sensor from the MAP Sensor Wizard. That is the best way to do it, just start over and see if it is giving you good data. Also what kind of map sensor do you have?

 

Select the appropriate Map Sensor Wizard. Just like TheBoz said.

 

Appropriate map sensor is selected. 3.5 bar aem map sensor.

 

Don't pay attention to what you boost controller says.

So during idle it says its seeing 8 psi of boost???

 

Yes it was, however its fixed. I went through and clipped every unnecessary wire to the ecu and reselected the proper map sensor and it worked great, so now just getting the car to idle right, then it goes to the hands of david buschur to get tuned on the rollers.
