fuel and timing will be way off

A'PEXi V-TEC AFC.
A great unit that piggybacks on the standard ecu that has a vtec option and fuel adjustment capability thru the whole rpm range. Not to expensive either...
Fields SFC-VTEC.
Basically the same thing as the A'PEXi unit. It allows for fuel and vtec control.

You send them a stock CRX ecu and they reprogram it. There are several options here.
Cheapest is their One Wire Conversion. They basically just put a vtec feature on. This is a good option because it doesn't rely on any piggyback units to activate the vtec. The bad is that it's not an adjustable unit so you will need something like an adjustable fuel pressure regulator to lean or richen the fuel mixture.
The most expensive is the Gold Secu. It's fully adjustable. You can change fuel AND timing, move vtec activation, control NOS or boost etc. Very nice but prohibitively expensive if you're on a tight budget. A good investment if you plan on keeping the car or changing your setup in the future. It pretty much does it all.
RPM switch.
Very cheap, very easy...but you get what you pay for. You are going to have to get a fuel pressure regulator so you have some control over mixture. The adjustable cam gear is also a good idea because with this, the only timing adjustability you'll have is how far you can turn the distributor, which is (more often than not) not enough.
