wuz up. i plan on building a B20 VTEC turbo setup for my 95 ls and im trying to get all my ducks in a row b4 i start. i was looking on hondata and didnt see a s200 application for it. can i even run data with this setup? oh i plan on using a B16 ecu btw

 

Since you'll be running VTEC, pick up a P28 ECU (from a 92-95 EX/SI). You'll need the S200 with boost option.

 

will i need the harness with the ecu

 

No you're already obd1, just stay with an obd1 wiring harness.

 

I agree, don't get a B16 ECU because you won't have a knock sensor on your engine. The P28 is EXACTLY the same ECU as a P30 but it doesn't have the knock sensor board inside. With no knock sensor, chipped P28s and P30s are identical, so get a P28 and save cash. As far as the B20 VTEC goes, it's all about the Hondata program you start with. You're not the first person to run that engine setup on a P28, and it should be really easy to get a basemap program to start from.
