Direct Connection performance timer-P4349443

autoxcuda said

I've had one on my Barracuda for years. Same exact unit with with different pictures on the packaging and no MP stickers on the unit. Works good. BUT whenever you disconnect the battery you have to recalibrate. So you need to write down and save the pulse number count.

I disconnect my battery nowdays since I don't drive my car daily. So the unit doesn't get used much.

I hooked it to to the right front tire at the outer tie rod bolt.

Hi everyone, new member, first post here.

Please forgive me for bumping such an old thread, but I've been trying to find some information on this DC Performance Timer computer and ran across this thread from a Google search.

I have the Zemco version of the same computer. (Zemco was the parent company that manufactured this computer, DC re-boxed it and sold it under their label as did Ford Motorsports; p/n M-10929-A100 should anyone be interested)

Anyhow, over the years I've lost my installation manual. I just installed the computer in another car and I can't remember how to access the calibration code once the computer has been set, nor how to re-enter it.

Any help here would be greatly appreciated. :help:

Thanks!
Eric
