I really appreciate you letting me know about your ECU version. I will call up Subaru tomorrow and see why I have not been notified about the TSB. If the flash turned off the tach sweep that would be a change in DEFAULT behavior as mine had/has the tach sweep turned on from the factory. If I can talk Subaru into giving my car the flash, I will let you know if mine gets turned off.
I don't understand why people can be so grumpy?
