Hey, I purchased a '96 hatch with a B20b in it, and the guy said it had a GSR ECU. I know the guages are from an Integra, not sure if that matters though. On the ECU itself there is no stamped number, but there are 3 printed letters: ABJ

I want to go with a Hondata setup to make a future turbo install much eaiser on the wallet when I do upgrade.

 

Look into the crack above where the plugs go in...There should be another label in there and you can make out the exact ECU...I had this automatic SI ecu running my car for the longest and thought at least it was a GSR auto...Heck nah...Sucker said P30...And I didnt have the side label either...

 

Here's what I have. I found a serial number, but I can not find a "Pxx" number. Any hints? There is deffinately some sort of an adapter cable between the orrigional connector and the ECU. Could it be that I have an ODB1 ECU now? My PC won't connect and recognize this ECU like it does with our '99 Si (with an adapter cable that is).

 

that looks like a p28 to me.
on the bar code on top of hte plugs is there a part numerb there?

i know uts not a p72 or p30 since both of those have a knock board and hta tone doesnt.
