I have a 98 civic ex. I had an engine swap and now i have a (si 2000) b16a2 but when i swapped the motors my wiring harness from the b16a2 didnt work right. So now im using my old sohc ecu and wiring harness instead of my b16 ecu and wiring harness. It works fine and all but my rev limit is only at 7k rpm instead of 8200 like it is supposed to, so i really only have the d16specs. I need to know if i can buy a chip and maybe have it saudered into my ecu and still use my d16 wiring harness, Im not sure what to do. thank you
