    i put an obd0 auto ecu on one of my old DAs with a b16a once.... it made the vtec crossover lower and the redline lower, but otherwise drove pretty normal. i think there was a cel on from it too, but it was about 8 years ago so i hardly remember :p

    there is a way to tell on the ecu.. the last 3 digits have something to do with a auto or manual like PR3-A01 i think is a manual I found a site before that tells you..
