Honda Transmission Question

[fmfkid250]

@Craze Z

ok I have another question and instead of making a new thread I will just askin on here

again - friend doing swap - got b16a2 engine out of 2000 si. He now agrees with me and needs a transmission also. But the new question is about the ECU. Does he need to get a new ecu? Or are they the same or is there any sort of jumper harness that he can use or what? I have no clue on ecu’s. All i know is its a stock 1999 obd2 ecu out of a manual civic.
Thanks in advance.

just get a obd2 comuter out of a B16a2 it will plug in,

I think the number is P30
