Dallas Mustang Speedcal Code Problem
I installed my speedcal and its working but my speedo is WAY off, i went from 3.27s to 4.10s. The 0010100000 code is the wrong code, I been surfing search engines trying to find a diff code and I keep seeing people saying theres two different speed cals and two different sets of codes but I cant find an alternative codes. Not a single speedcal code int he instructions starts with a 1, but when I got this unit it started with a 1, and even on dallas mustangs website for the instructions the code they use in the example picture for 3.27 to 3.73s starts with a 1, but when u got to their "new" chart I guess its not the same code? anyone have any clue here.

There are two Speed Cals (regular and Extended range). You'll need to match the code with the right version. Did you call DM and ask the place that makes them?
214.349.0991 - Ask for Justin. He's the Speed Cal guru. He'll probably have you set #1 and #4 up, the rest down, then pace another car for a known 10 miles and record what the odometer says you went. Then he'll give you a specific 'up/down' pattern to set based on that number.
The codes aren't out floating around on the web b/c too many people were screwing them up.
