Which ECU should I get?

Well I got a problem with my ecu right now and I have to get a new one and was wondering should I get another pr4(obd1)or should I go with the p75(obd1)? I actually have a 95 b18b1 block with a 91 pr4 head with cams from the head of the b18b1, with a 92 intake manifold. I know it isnt going to make a big difference which ecu i get but I have read that the p75 has better "fuel maps". Which ecu would be better for my setup?

I'd get a stock OBD1 B18B1. The best option would be a custom tune but you should be ok with using the stock P75 map since you're not using aggressive cams.
