how do you change the motor from obd2 to run obd1... with skunk2 adapter right?

*my car is obd0... will the sk2 harness work for my needs?

 

90 teg ecu and distributor if you have obdO

 

use obd2 harness with obd1 ecu. depends on what car you putting in

 

The '90-'91 teg ECU will be the closest match for the B20 without doing any rewiring but it tends to run the B20 a bit lean. You could also try to use an '88-'91 Prelude 2.0Si ECU, it has a B20A5 which gets its extra displacement from a longer stroke instead of a bigger bore like the B20B and B20Z. Either way you'll probably need some kind of fuel adjustment to get it running right.

 

You cant run a harness converter between OBD0 and OBD +2 because there is no provision for heated O2, the wires to the distributor are different. Then there is a different number of teeth in the distributor for crank angle so it will spark once fire and never run again.26 versus 32 then the timing will always be off that is if your talking B20b or z from CRV,SMX or Stepwagen. If so then thats your answer. Chip the PR4 for more fuel and use old lude injectors.
