HI there,
The ECU has been around since 2006 with LNF 2.0 Turbo charged vehicles, which is where this may have come from.
But lets not forget the firing voltage of these injectors is higher than the normal 12 volts so that may change dwell time along with other factors.
Nevermind the wideband oxygen sensors that are used now that were not used on previous generation of Corvette.
Allthebest, TCM
