Yes Ed, wasn't sure about others, my ECU-882 has that ability however I've yet to do any serious testing using it. Would be interesting to hear from someone that has. At higher engine speeds I'm imagining a serious amount of feul vapor being flying around in my manifold....is it a detriment or a help...I'm not sure.I've even wondered if my manifold design since it was made for a carb is a hinderence guess time will tell. BTW my car has ran as fast if not slightly faster with the EFI versus the carb, though again it may be contributed to the manifold and head design more than the actual delivery system....sure can't beat the EFI throttle response though.
