B20 swap sensor questions.

[Bear05]

Here's the setup, the motor's a bone stock B20B4 from a CR-V. The ecu's from a '95 Integra, and I'm not sure where the wiring harness is from. On snap-on's shopkey program the harness lines up perfect with the harness from a '97 Integra. The issue I'm having is figuring out how many sensors can be missing and still have the car running somewhat decently. There's no O2 sensors, maf or map, iat, or oil pressure sensor. The car has a long tube header with no bungs to add O2 sensors, the iat sensor has the wrong plug, the intake's some cheap ebay cold air intake, and the oil pressure sensor was removed in favor of a mechanical gauge. Will the car even run without all this hooked up? I'm building the car for racing and my class does allow tunes so need be I can get the engine tuned. Any advice y'all might have would be huge.

generally, use your car's chassis harness. adopt plugs where necessary to cut/paste on or run wires. the ingetra b18b/Ls/gs/rs car/engine are 95% the same as the b20 and should plug right up.

you will need the o2 and map and iat, or it will throw a code, putting it in limp mode (eg, 20% power).
The pressure sensor shouldn't matter.

you CAN disable o2 readings in most software. This basically keeps it running the program, and not the enginen's actual feedback via sensors for closed/open loop.

we don't have MAF's. we use MAP sensors. it's required, even for tuning as the plot is based on rpm vs map
