Hi everyone.

I have a very old but brand new fast grey box I was thinking of installing on the buick.

There seems to be no lockup control in the fast grey box program, I thought there was but I think thats XFI the newer version.

Would a person just jump the ALDL port to a switch when desired to turn on lock up ?

Does the ALDL port even work after installing a different ecu ?

Let me know thanks.
