Normally with a dry shot, the regulator is connected into the nitrous system. When the nitrous is activated, the regulator is pressurized increasing fuel pressure which increases fuel sprayed into the engine. I just looked over my CBAZA strat and I see some references to N20 but nothing specific to enrichment. I also dont know how the ecu would be triggered to go into N2O mode. Without the CCRM you will need to add fan relay(s), fuel pump relay and ecu relay, I dont know how beneficial it really would be to eliminate the CCRM because youre just going to have to add the relays back in. ABS can be disconnected or removed, egr can be removed but the position circuit is usually used for wideband monitoring.
