Outline
1) 97 honda accord coupe
2) swapped f20bsir engine(automatic)
3) original f20b sohc non vtec automatic transmission and ecu
4) apexi afc neo(to engage vtec)
5) harness is obd1

question:
I have read that the h22 and the f20b are similar(f20b is a destroked h22). Due to my current setup as mentioned in the outline, my car isn't performing as it should. I have purchased a h22(p13) auto ecu but apparently it doesn't work well with the original tcu. So, could i purchase the h22 tcu and plug it into my transmission and the h22 ecu for the engine and see if it works better? thanks.
