B18c1 swap into ej8 sedan ecu questions

[619ej8]

Hi guys! New to the site...

Chassis: 1998 Honda Civic EX Sedan
New Motor: 2000 B18C1

So from doing some research, I'm currently OBD2A and the new motor is unfortunately OBD2B. I purchased the complete swap with wiring harness and OBD2B ECU. If I understand what I've researched, I have the following options:

1) Because the OBD2B ECU has an immobilizer, I can send the ECU to a place that will re-chip the ECU so the immobilizer is no longer an issue, and buy an OBD2A to OBD2B jumper harness

or

2) Obtain an OBD2A ECU and I'll have no need for a jumper or re-chipping (which to me sounds like the way to go). I also think I understand I will not have any issues with BAR or smog going this route.

Am I missing something? Can it really be as easy as option 2? My research has also lead me to believe that I do not have to get a new harness or need a jumper because 96-01 harnesses are all OBD2 and have no designation of A or B. Any help would be greatly appreciated. Thanks!

I would definitely do option 2 and get an OBD2A GS-R ECU. If your car is a 5-speed, you can use your factory engine harness from the D16Y8 and everything should plug and play. The only plug that may be different it the IACV, but that's a simple fix. Its either a 2-wire IACV or 3-wire IACV. Look up which one your car has and which one the engine has. There are multiple DIYs on that.

If its auto, find a 96-98 5-speed harness and do above.

Hope this helps!
