I have a 97 civic ex with a jdm b16a swap. The current ecu it has is the P2P(stock ex one) and I have a P2T(from 99-00 civic SI) I wanted to use the P2T, but im not familiar with this stuff, thought it was pretty simple, but it does work. I have attached pics. P2P fits fine but on the P2T there is no spot for the small plug on the left. I belive the guy I got it from said he had the ecu chipped. not 100% sure

 

The p2t is obd2b. Your car is obd2a.

You can use an obd2a to obd2b ecu jumper, however they are expensive & you would throw codes for obd2b sensors you don't have.

Do your self a favor, buy an obd2 to obd1 ecu jumper and chipped obd1 vtec ecu.
Read http://www.phearable.net/tech/efibeginnerguide.html for more information.

 

What codes would he throw ? if he went with the p2t ? Not trying to say your wrong just curious.

 

I am plannin on turboin later on down the road, should I just get hondata?

 

I'm not 100% sure, but I believe one of the codes would be for the charcoal canister/evap and fuel tank pressure???

Yes, as previously suggested a jumper from OBD2A to OBD1 and a Hondata S300 equipped OBD1 P28 will be much better than the 99-00 Si ECU..

 

Yes, you could buy an obd1 ecu with hondata pre-installed and use an obd2a to obd1 ecu jumper.





You could also buy a obd1 ecu with obd2a plugs installed so you don't have to use an adapter harness.



If you are going turbo down the road I would recommend you purchase the boost control bundle with the hondata so you are ready to go!

 

Thanks 4 all the help and answers. Nice to know what I need and not waste money

 

No problem!

 

i found a obd2a to obd1 jumper used for $40. Is this a good deal? should I get it?

 

Depends on what quality it is. We have seen countless customers come into the dyno with harnesses that are falling apart due to poor quality.
