ooh i got one tid bit of info for you for when you go with the 7th injector part of the project...

make sure to use the dual table code to run the 7th injector... the standard code injects fuel even if the VE map is set to 0% across the board cause it still takes cold accel enrichment into account amongst other values... the dual table code was designed to run progressive nitrous control, so 0% means 0 pulsewidth no matter what...
