Just completed my SpeedCal install, so I thought. It doesnt seem to be working right. Where can I find the settings to the upper dip switchs?
I dont have the extended range unit. There is no E on any corner of the box. The instructions only tell you how to set the bottom dip switchs not the top. The top switchs are the only thing I can think of that might be my issue. The problem is I have to get this install completed by sunday night. Dallas mustang isnt open until monday so I cant call them.
What happens is when I go in gear the speedo will move up slowly until it gets to 10 MPH then it will just drop down to zero. No matter what gear I am in.
The first two runs are in first gear, the third is in third gear.
As far as I can tell everything is hooked up right. I used a switch power source from the radio and had a voltmeter on during the test and it held 14 volts the whole time the car was running. (12 with engine off key on).
I have the blue and green connected to the vss sensor. The sensor worked fine as I tested it just before starting the install.
The grey wire goes to the (origonal vss) ground wire, the pinkish with org one. Same as it says in the instuctions and I have tested it with a voltmeter as well.
Does anyone have any suggestions on what else it might be if its not the top dip switchs? Im puzzled.
In case anyone wants to check my dip switch settings it is for 4:10 gears, 245 45/17 tires with the stock speedo gear.
Car is 1996 Cobra Coupe.
Thank you for your help.
