Is there a way to convert the obd 2 d15b to obd 1 and run crome on it while still having 3 stages? I figure if there is a way to make crome flash a check engine light at a certain rpm then it would be possible to have that same function activate the first solenoid to lock in 16 valve mode, and have vtec crossover as normal. It could be tuned for the stock 20:1 afr's until say 2700rpm and from then on tuned normally... anyone have any thoughts or insight?
