it's been said that an Integra P75 ECU will work with the B20.
B20/vtec, i would guess a chipped P28 ECU is best for that.

Re: ECU WHAT IS THE DIFF. ? (skip.two)
Doesnt really matter between p28 and p30 ,,both will need to be chipped with different fuel and timing maps anyway to run the 2.0L vtec correctly..But I would go with the p28 just for the fact that they seem to be for sale everywhere..

As far as features. (chipped ECU)
P05 = base ECU
P06/P75 = P05 + O2 heater control
P28 = P06 + VTEC control
P30 = P28 + knock sensor
P72 = P30 + IAB control
there are several other OBD1 ECUs out there but these are the easiest to find ones.
You can make the decision as to which you need.
If you're staying with the B20, the P06 or P75 would be fine. If you plan on switching to B20/VTEC then the P28 or P30 would be best.
