You'd be better off picking up your own obd1 ecu, get it socketed so you can change the chip whenever you want...all you have to do is buy the chip, pop the old one out, and pop the new one in. Check out www.ag-eng.com they have tons of chips available, and do good work. Their list of chips is up, but I dont think the site is quite finished from what I saw, but they do have a phone number to contact them..great customer service.
