Hi . A quick search found this . Perplexity.

Here are the best options currently available for a 1982 Corvette ECM (Engine Control Module), including part numbers, pricing, and where to buy.
Key part numbers for 1982
The 1982 C3 Corvette with Cross-Fire Injection uses GM part number 1225550 (also listed as 01225550, 77‑5550, or 775550).�
Where to buy
Dino’s Corvette Salvage (used OEM)
Item: C3 Used Engine Control Module (ECM) 1982
Price: $695 USD
Notes: Good used unit, listed for 1982 Base and Collector’s Edition. Call for availability.�
Link: corvettesalvage.com
AutoECMStore (refurbished)
Item: Refurbished ECM for 1982 Corvette (part 1225550)
Price: Listed with a $200 refundable core deposit (total price shown on product page).
Notes: “Like new” refurbished unit.�
Link: autoecmstore.com
eBay (used/various sellers)
Multiple used Corvette ECMs appear regularly; some listings explicitly mention 1980–1982 compatibility. Prices vary widely (often $300–$500+ depending on condition and seller).
Tip: Filter for “Engine Computers” → Chevrolet Corvette and confirm the listing mentions 1982 or part #1225550.
Private sale / forum wanted ads
CorvetteForum has active “parts wanted” threads specifically seeking a 1982 ECM (part #1225550), which can be a good place to post your own request or find a private seller.
Example listing: a Collector’s Edition 1982 ECM sold privately after being swapped to a 1984 unit.
Important notes for 1982 ECM swaps
A 1982 ECM can be replaced with a 1984 C4 ECM without rewiring; this is a known “swap secret” for these cars.
Dino’s also offers a rebuilding service for 1982 (and 1984) ECMs if you prefer to send yours in.

Okay let's start here. Don't buy another 44 year old computer unless you want more problems. Xfireperformance used to sell a replacement but is manufacturing a new improved unit that will make your crossfire perform way better than stock. It should be available in the next month or 2 as they are doing the final tests before manufacturing. Is is also fully tunable. He is also shortly coming out with a Renegade 2 intake manifold that will add about 40 rear wheel horsepower. I have owned both of the original products for my 82 Vette but have sold the car and the ECM and the renegade. Be patient and get in touch with Xfireperformance. Anything else is just throwing your money away on an obsolete product.
