Yeah, it burns the eyes. This is through closed exhaust.

Just trying to get it back up and running. Had to send to unit out for repair due to a failed injector driver. Holley stated they also replaced the ECU. Tune was blanked and it wouldn't load any of the saved tunes off of the SD card. Might be because the firmware is newer than tune saves, dunno. Ran the initial setup again and figured I would let it self learn again.
