I still cant get rid of the stupid P0300, and Im starting to think it's not the ECU+ or the cams... Tom has fixed it for EVERYONE else but me. I heard Mitsu made some flash for the P0300 problem, and I'd like to know if anyone has an '03 Rom that has that flash so I could copy my maps onto it and see if I can get rid of this thing. Thanks in advance!

 

Check what your MAF reading is at 2000-2500rpm, if you can get your snapshot info, I was getting the P0300 until made some adjustments that allowed fueling and timing to transition from closed to open loop a little smoother. The P0300 for me was most obvious when the MAF reading was slightly too high also.

 

MAF HZ is 203-219 from 2K to 2.5K when throttle is ~33%. I have attached pictures of both ECU+ and Mitsulogger logs. The area where you see knock I believe is due to my cams being too aggressive (+2/0) which I've since changed. But the problem is OBD always says the P0300 is at idle... I could go grab a screenshot of it too if you like.
