Hello,
I have a B16A2 (Which is OBD II I believe) Swap in my CRX, here are some photos of my ECU:





Is this an OBD II to OBD I conversion harness going into a OBD I ECU?

Also if I buy a chipped ECU, I should be able to just hook it up an go right?

 

looks like your car is obd0 and u are using an obd1 ecu maybe u have a p28 ecu

 

yea that is obd0 with a rywire conversion harness. You can put the computer in yes. What all is done to your car and what chip is in the computer

 

take a picture of the barcode.. or the male plugs on the ECU

make it easier to tell what kind of ecu you have..

 

Check the code on the back, then look here:

Looks to be a obd0 to obd! harness because of the pigtail. Stock b16 ecu's were PR3 and P30, or it could be any chipped vtec obd1 ecu.

 

Well I know VTEC doesn't totally engage until 6k RPMs and the rev limiter is at 8k. I checked the ECU and it's blank on both sides, I haven't disconnected it to see the back, I thought you would be able to tell based on the plugs going into it.

If you remoce the top ecu cover, there will be another sticker with the ecu code written in the middle telling you what model it is.
