Hello my fellow sx riders, I talked to ECU flash company the other day not gonna post any names on here. But I'm sure you can guess who. to Make a long story short I sent ECU in Tuesday USPS said it will be there Thursday. They are going to write a flash for the sx 20 and up so everyone will be able to enjoy the full potential of these machines. Also get the fuel/air in order on Dyno. I'll keep everyone up dated. Hope this is good news for most
