I have a new fuel injected engine in a 68 Camaro with a 69 Camaro cowl induction hood with a flapper that would normally open from throttle pedal linkage that would send a signal to a solenoid that would open the flapper. The new engine has drive by wire so there is no linkage to operate the flapper. The flapper has a solenoid that opens and shuts it. I know the DBW signal ranges from .5 volts to 5 volts depending on pedal position (.5 volts at idle to 5 volts with the pedal floored). I want to somehow get the flapper to open with just a little throttle pressure so I figure somewhere around 1 volt would be a little off idle. Is there a way to get this solenoid to open the flapper at the 1 volt signal and shut the flapper when the signal is below 1 volt?
