As you might have seen, I got a B18c1 installed in my coupe over the weekend. Its a stock B, with only intake/exhaust. I was originally going to get a B18c5, so I got a chipped P28 ecu with 5 chips: Jun, Mugen, Skunk2, Stock, Custom N/A.
I'm wondering what ECU would be best to run on a 95 GSR?

Can I use the chipped P28 with a ITR chip? Should I just use my stock P28? Would a 95 GSR ECU work best?

What chip would I need to run Hondata? I'm planning on getting that next month, but need to know what to use for the time being.

Thanks!
