megasquirt and aem
Hello all. I megasquirted my miata today, Woohooo for tunerstudio haha. I uploaded the basemap onto the controller and everything seems to be running well. Timing has been verified at 10 and after a few pulls using autotune the car feels very smooth. My only issue is no matter what I have tried my wideband wont communicate with the ecu. It was and is wired into my wiring harness and was sending a simulated narrowband to the stock ecu as per the "p04" setting. I tried to continue the narrowband signal to the ecu with no luck. I also tried to switch the aem to p00 and then calibrated it in as a custom linear wideband. neither option allowed the wideband to communicate with the ecu. Any suggestions would be greatly appreciated. Id really like to keep the wiring setup i have if that is a possibility as well. Thank you. the Ecu is a MSPNP2 v1.2 and the wideband is an AEM 30-4100.

Verify the wire color you used from the wideband? On an AEM wideband this should be white. Next use a multimeter to see what the voltage you are getting via this white wire is like. Anything above 0V should be showing some sort of value in TunerStudio above 10:1. If both of these check out, that should prove it to be a software/calibration issue.
