Factory computer - engine upgrades

[Boony405hp]

Who here has done things such as cam upgrades etc with the stock factory computer? What do you use to change the settings? I know the factory cars use Diablo tuners and plug in to the ob2 port. What would u do on a muscle car that has the computer only and no ob2 port?

With the correct harness you would have the ODBII port. We still use Diablo on the swap cars as well.

I have the hotwire auto harness. Thanks. I didn't realise it was part of the harness but after inspection I can see it is. I for some reason expected it to be a direct plug in off the computer somewhere.
