Ok so my VTEC is strong in 1st gear, is choppy in 2nd (ie. it cuts on and off 3 times between 5200-8200 rpms), strong in 3rd but my rev limiter hits at 8000 rpm (only in 3rd gear), choppy in 4th just like 2nd, and works like a charm in 5th. My oil pressure is fine and as far as i can tell the wiring is right because its semi work in three gears. Any Ideas? My other question is this, im putting a turbo on my car and im using a p28 ecu. I have the jumper harness to convert my car from obd0 to obd1 but am i going to have to buy an obd1 distributer? Thanks for the help guys.

You will need a OBD1 dist. and a OBD1 4 wire o2 sensor.

 

You will need the 4wire O2 sensor and you will need an OBD1 dizzy. If you're running the z6 head you will need the z6 dizzy. If you're running the y8 head like me, you'll need the 92-95 dx/lx dizzy (d15b7) what will you being tuning with? how much boost?

Good luck.

 

If you are going turbo and getting it tuned you wont need the 4 wire o2, they will use a wideband to tune, then delete the o2 after its tuned so the computer wont read it anyway

 

Thanks for the help guys, and ideas about the VTEC though?
