I tried to find some theads related to this. I thought I remembered someone doing it a year ago. I am really debating either going MegaSquit 2, or getting HP tuners. I currently have a 95 2.2 ohv motor, and the 95 computer.
I haven't made a decision either way, but was wondering how hard it would be to switch my car's computer to a 97 computer, so I can use HP tuners. I figure I would obviously have to get a 97 2.2 ecu. Then, ofcourse i'd have to get a engine harness for a 97 ecu, because my ecu has 2 plugs, and the 97 ecu has 4 plugs so I know they are different harnesses. (does GM sell entire harnesses?) I am hoping the Knock sensor would be the same, and as I understand it, i can delete the second O2 sensor inside HP Tuners, so I wouldn't get a check engine light by not adding a second O2 sensor.
I just pulled a 97 ECu out of my car (fried), and its only 2 plugs...
black and blue connectors, 80 pin
Should just be plug and play as far as I know.

Hmm, my 95 ECU has two plugs on it (1995 2.2 ohv Automatic). I had seen a 97 ecu, and could have swore it had 4 plugs. It had two rows, with what looked like 4 plugs. Perhaps it was two plugs, but that would mean the singular plug was twice as long as the two on my ecu.
Perhaps I was wrong.
Yeah im looking in to this as well. I have a 96" I all ready have a 99" ecm to delete the egr i just need the wireing harness. Then i want to get the HP Tuners as well so im in the same boat as u bro.
