Check out b2600i.com he's a good guy. I know he deals mostly with the 2600s but send him an email and check and see if he's got any 2200 ecu's or if he can refurbish yours...
if anybody can point me in the right direction or have one laying around and would like to get rid of it let me know i've searched online,ebay(too rich for me ) craigslist and local bone yard ( pick n pull ) with no luck will try again tomorrow
I found this on the other forum, it's a post with similar issue that you have. Try looking up AVPro. For what I read, $160ish for repair with lifetime warranty (if it can be repaired that is.) worth a look.
