Hondata's a bit overkill depending on how built his engine is. If it's fairly stockish and he plans on keeping it that way, then a chipped P28 with a simple tune for a stockish B20/VTEC should work fine.
OP, for some swaps and hybrid builds you can find a stock ECU that will be close enough, but for this setup you really need a chipped P28...
What base map should I get if I choose to go with HA Motorsports socketed and chipped P28 ODB1 VTEC ecu ? They give choices for : P28 D16Z6, P73 B18C-R , P30 B16A, P61 B17A, P72 B18C1. Also with whatever ecu suggested will they know when put when the VTEC should kick in ? It seems they don't provide a choice, I'm not sure; but I was looking at Phearables chipped OBD1 VTEC ecu and it gives you the choices to adjust map sensor, rpm rev. Limit and VTEC engangent point. But I think they all are set to 5500 rpm. I have a pretty much stock set up 2000 B20 crv block and 2000 B16 head and I got the VTEC solenoid connected. Who should I got with Phearables ecu or HA Motorsports ?
Would I need knock control ? The ecu's I'm looking at like bypass it they are disabled. Also would the sleeves and rods hold up with daily driving ? Long as I'm Not pushing the car too hard. Any shops to recommend for ecu chip tunning ?
Also if I get the integra type r map will it be ok ? Should I just go with HA Motorsports socketed and chipped P28 ecu ? If I do decide to go ahead and use theirs, you said to use P73 B18C-R map. That's the itr map right ? I was told also if I go with the itr map that I will need a a jumper harness. What is it OBD2a to OBD1 ?
You don't have to have knock control in your ECU after your tune if you tune everything properly to eliminate knock... but a knock sensor and the ability to compensate for it on the fly are both a VERY good thing. FYI, I never ran a knock sensor on my builds- they were all OBD1.
Thanks a lot that really helps. Also if I was to get the p28 ecu but a p30 base map would that be alright ? Or could I go with p72 b18c1 or p73 b18c1-R base maps ? And if I used either of the p72 or p73 would I need a conversion harness from obd2 to obd1 technically if its still the p28 ecu but just the map for p72 or p73 that your using ?
