I'm going to be using ktuner to tune my car once I get my sprintex installed. I have been messing around a little with it and I noticed that I don't seem to have all the features that other ECUs have. I know that the 37820-RP3-A54 ECU was still being developed for ktuner so I was wondering if i could swap to the base model 2009 ECU A53 37820-RP3-307 without too much modification. Thanks
