ok,my friend just bought a crx with a d15b in it. It's supposed to have an 8200 rpm redline according to what I read on a website that sells the motor. His redline's at 6800 rpm's but the block does say d15b~ so wrong ecu, my question is, could it just be chipped? and how much would that cost roughly (j/w what a ball park figure would be).... if anyone could lmk I'd apprecaite it, thanx
