AEM FIC fight for turbo!!!

Good advice, I will check into that more. I went through and looked for a loose ground somewhere but couldn't find anything. I'll check again though. A guy on the AEM forums suggested I try all the different firmware versions because apparently each formware version applies better to different vehicles. I know DKN-YARIS went through all of the different firmwares so I'll refer back to that post. Another suggestion from someone because of my misfiring issue is to upgrade the coils? Has anyone had a problem with the stock ones with turbo? AEM High output inductive coils perhaps? Just think for such a basic turbo build it seems like overkill and it shouldn't be misfiring with my current setup.

Edit: ehh, just thinking about it and high output coils don't really make sense because I don't think it misfires when I bypass the FIC.

If anything you could have a coil that is starting to break down or a misgapped plug. Upgrading the coils would really not be necessary.

The best way to check for ground issues is with a multimeter. Put it in resistance (ohms) mode and measure between the negative battery terminal and ground points. Besides checking large metal chunks like the block, any wire that is white with a black stripe is a ground, and you should measure very close to zero ohms between it and the negative post.
