Help with speedcal settings?

[Ghost]

I just swapped a magnum t56 into my 1996 Cobra. I have a Dallas Mustang Speedcal and need some help with the settings. I am running a 3.55 rear gear.

Can anyone tell me what settings I need on my speedcal to have my speedometer accurate? It would be greatly appreciated!

Do you know if it's extended range

are you using the t45 sender in the magnum? If so, its exactly the same as just going to 3.55s, which should be 0010001011
