Yeah, really curious to know. I had some pretty serious problems with the original VT2-500 tune on California 91 octane gas (highest available here, always from top quality gas stations), and they revised it for me, but I'm not sure if it's been updated again?
Is it possible to apply their updated tune with the ESS flasher unit, or do you have to send in the ECU?
