I just got a 91-95 JDM D15B SOHC VTEC motor rated at 130hp with a redline of 7200rpms. The computer it came with is a P84 which is definately not correct. It seems like they gave me the 3 stage ecu since vtec hits at 2,800rpms and fuel cutoff is 6,100. Does anyone know the correct ECU for this engine?

 

I'm not 100% sure. But I believe the JDM B15B is a P08 ECU with 3 stage VTEC.

This ECU is rare and haven't seen much of them. I would recommend you run an EX/Si P28 ECU.

 

i bought one of those ecu a while back.... it didn't seem like there was any difference... rare maybe.. the thing is that the guy who sold it to me didn't know what he was selling i guess and i got it for a cheap price..... under 100$
