computer upgrade
Hi Guys. I have a 82 crossfire that is mostly restored. It runs well but I have come to the conclusion that the computer need to be upgraded. Can anyone steer me in the correct direction?

Re: computer upgrade
Well old buddy....I'll tell you what; How about I just copy and paste from another thread, where you were SO helpful!...
So yeah... what your after is easily achievable. I'd sell you the "secret" but you won't be able to afford it.
there are a lot of things a guy can do in the assembly process to free up quite a few poneys.. "these are speed secerets" I'll sell you the secerets but no one has been able to afford them yet.... LOL
There are some things done that I WILL NOT TELL as I get paid to do these things.
a good crew chief don't devuldge his secrets. I do not care if you do not believe me as I have no reason to lie.

ebl flash

* Crossfire Corvette:
For the EBL Flash ECM to work in a Crossfire car some additional changes are required. This is due to the type of connectors each ECM uses. The Crossfire ECMs use an edge card connector, while the EBL ECMs use the pin style connector.
Basically there are three options:
1) Replace the EFI harness with one from a TBI car/truck with the proper connectors.
2) Cut off the current ECM harness connectors and splice on the pin style connectors.
3) Have a HAM board installed into the EBL ECM. See DCS at http://www.crossfireinjection.net for the HAM board & install.
http://www.crossfireinjection.net/catalog.htm
HAM Board
Item Name: HAM Board (IN STOCK)
Item Price: $130.95
Item SKU: DCS00013
Shipping USPS Flat Rate: $12.50
IN STOCK
Product Description Convert the GM 127747 or 1228746 TBI ECM to be plug and play compatible with the existing stock CFI harness connection. No need to splice your stock ECM wire harness. Just install the HAM module into the new ECM, plug it in and you are ready for laptop tuning. NOTE: Unsoldering and re-soldering procedures are required to the ECM board for installation, additional hardware and software may be required.
