The P72 is the wrong ecu, because it is optimized for the GSR intake manifold, and GSR cams, with a really low vtec level. Plus you will have to add a knock sensor.
The P73, ITR ecu, would be the closest to a 1.8 Vtec. But those only come in OBD2 flavor, which means additional wiring of sensors.

The P30 and P72 can both be chipped to work well with an LSVTEC. VTEC point can be changed on the GSR, and the P30 can be mapped with more fuel if need be, although it would run fine on the stock ECU. I too would run a P28 simply for cost factor over the other 2, and they are easier to come by than a P30.
