My ECU is not flushable unless though KTM.  In the USA, KTM’s are so lean that the exhausts will melt the plastic shrouds if run long enough, I’ve seen it happen on Hsuky’s and KTM’s first hand, even with the end cap uncorked. Basically there is no way I’m going back to a stock ECU just to get my dashboard (DMD) working.  I don’t know another ECU option on the market?! I recently tried calling Best Dual Sport Bikes to ask them about getting readings off his ECU and the owner basically hung up the phone on me mid sentence. Not sure what to do at this point? Dead End. Bummer.
