I have a toyota matrix xrs i now this is not the rigth forum because this is for scion. but i write here if yours can help me to figure out my problem.
the problem is went i connect the fic to car and the car start without a problem but went i write the calibration the maps the car wont start

 

Hmmm... possibly the fuel injector sizing? Or maybe you need to calibrate the TPS and RPM inputs?

I'd go ask on http://http://forum.aempower.com/forum/index.php

Someone else there may have had this issue. Good luck!
