This refers to the dealer downloads on the ECM...
The only reason for having the ECM flashed is to up the rev limit to 6200 which serves no purpose with a stock motor.
The TFI will work either on a stock ECM map or an upgraded one (stage 1) but the TFI settings will be lower with the upgraded map.
From Dobeck Performance...
Our TFI controller will work with ECM re-flashes, but it does change our recommended pot settings. Our controllers are just 'piggy-back' controllers meaning we only adjust the signal to the injectors after the stock ECM has made its calculations. An ECM re-flash will change the fuel map which means we have to in turn change our settings to match.
