I'm converting my crx with 91 boosted ls motor from obd0 to obd1. I ordered a chipped obd1 ecu, I have the ecu and distributor conversion harnesses and obd1 distributor, do I also need to get a 4 wire o2 sensor or is it not necessary?

 

If you order a chipped ecu with the o2 sensor disabled, you won't need a 4 wire o2.

 

I'm not sure if the guy disabled it or not....

 

Who did you order it from?

 

A guy on ebay

 

Good luck. I have seen countless people end up having to buy ecus from us because their ebay ecus didn't work properly etc.

 

/end

 

He said he has been tuning hondas for a long time

 

yah and he probably sells neon underglows too. some sellers will say whatever they have to to get your money. you need a 4wire o2.

 

yea I just ordered one, when i get it how do i hook it up since the plugs are different, can I just splice into the plug?

 

bumpp i need to know that too lol im doing the same thing, Can the person that chips the ecu disable the o2? let me know too lol pm me or something with some facts
