I have a 93 Honda Civic hatch and I swapped the D15 that came in it for a B18 from a 94 Integra. I used the ecu and and the wireing harness from the D15 on the B18 and its running like crap. My question is can I use the D15 computer with the B18 or should I have used a B18 computer and wireing harness? What would you guys recommend?

 

why would you ask if you could use that ecu from the d15 did a integra come stock with the same ecu i think not common sense goes a long way

 

D series ECU for a B series, im not a computer genius but, I don't think your supposed to do that.

 

If it is a GSR then you want to run the GSR ecu cause a SOHC ecu doesnt have the secondary intake setup like the GSR ecu and you will notice a power loss from it. Run the B series ecu with the B series engine and do it right the first time so your not doing it a second time.

 

What exact ECU is in the hatch right now? That would be the first thing to find out.

 

whats the ecu right now
