Default Speedo correction

I am running 4;10s in my 93 M6 and was wondering how to get my speed odometer corrected.

You'll need to buy a Hypertech Tuner, one of the only good things that piece of junk does worth while. The other choice would be sent the PCM to a tuner.

Since it is a 93 and a M6 you have to get a speedo recalibration box. Dakota Digital makes one and the part number is SGI-5.

You can correct speedometer of a manual or an automatic with the Hypertech. 97badass you must be thinking of shift points for automatics

Bryan doesn't do the 93's, Alvin does. Apparently most don't realize 93's run a totally different pcm and cannot make gear changes.

Check out speeddensity.org for 93 specific information. There is a thread about using the Dakota Digital box.

This is the only correct answer so far.

I know, i have had people try to tell me the 93 is the same pcm as the 94 and 95. I have even had guys tell me im a idiot, im stupid and so on when i try to explain to them they are different.

Looks like the Dokota digital box is what ill be using, thanks
