Yes. You are correct pretty much. Car was pretty rich after the flash was done. Then since adding the flex fuel sensor and maps its maxing out trims. Afr's also look pretty rich it seems.
Side note. After installing the maps and following the process as exactly written in the read me file. The only thing I have issue with is the last step, after I hit the reset button the red bar at the bottom just says "ecu resetting" it never stops saying that. No matter how long I wait. (Tried it for a half hour once already lol). I know the read me file says it won't go back online, but should it stay in the "ecu resetting" state?
