Can I use my P28 ecu from my d16z6 to run a jdm d15b? They are both soch vtec engines. Or would I be better off spending extra money and buying the p08 ecu, which goes with the d15b?

 

I have the same engine and will go ahead and say to buy the P08. The P28's timing and fuel maps are not agressive enough for the JDM D15B. I am running mine on a JDM P30 ECU which I know is a OBD1 DOHC VTEC ECU but it runs it tons better than the P28 I have

 

sweet, thanks for the info!
