couple questions about my b series crx

Hey h-t whats up. So i recently had my bubble stolen and then bought a 89 crx si with an ls swap and i was dumb and didnt really hear it run or test drive b4 i bought it bc i needed a car asap. The car when warmed up doesnt run too great, motor is healthy ls and runs hard but it does some bogging and spittering, spuddering. I know its something electrical bc i changed the dizzy, main relay, fresh tune up, checked and cleaned injectors, no bad injector codes and revs to red line no problems, fuel filter, fuel rail, alot of stuff and then i remembered that the dude gave me a pm6 which the si ecu and after talking to a couple people they said thats my problem that i should have the pr4 ecu because the fuel maps are different. I just wanted to ask h-t to basically as a second back up opinion. Also the ecu running codes 1, 17 and 20 and tps.

Second i have my car for sale bc i was trying to make money off it to build something different but i decided to keep and build it with a beast b series lol. I have a 92-93 b17 block, and its usdm bc they didnt make in jdm and i have a 95 usdm gsr head and just wanted to know if it will fit on the b17 block bc i was trying to avoid the lsv right now bc im very short on money and reliability reasons and later on do an lsv turbo. Also i wanted to cut and rewire obd1 injector plugs on the obd0 harness so i can run the obd1 injectors, can i do this which out any problems.

Why don't you fix the codes? It should run "ok" with the PM6. Fix the codes before you do anything else.

Also throwing the GSR head on the b17 wouldnt do you any good IMO. Just save you're time and money and wait to do the LS-V.

The CRX was the previous owners project before hand, and they at one point decided to replace the factory motor with a B18A/B1. I had a momentary lapse of sanity and purchased it on impulse without actually checking the condition of the vehicle. The motor when operating at nominal condition does not run too great, but I don't know how to actually describe the issue. I believe the motor is mechanically sound, but it does bog and misfire which I believe is an EFI issue. I narrowed it down to the fact that the seller provided me with the wrong ECU and I continued to use that same ECU during the trouble shooting phase. I determined after consulting with various individuals who informed me that I should be using the ECU designed for the motor, which is the PR4 model. I wanted to ask fellow contributors on Honda-Tech for another opinion, even though my intuition screams that I should be using the proper ECU for the motor. As well, the EFI system is showing the following error codes: 1, 17, 20, and throttle position sensor.
