There are 7 modules in the K67. anytime ISTA connects to the modules it will update either all of them depending on current code, or just the one needing update. the one thing you cannot do is select only one module and ignore all others if they need updating. So, it makes it complicated to leave the flash tune in the ECU and allow ISTA to connect. The flash tune process can only update the ECU, where if you work with me directly, I can update all modules in the bike, or maintain a previous working code back to the ECU so that you get exactly what was already running great and you know the character of the tune.
