Jimmy825 Posted January 21, 2022 Share Posted January 21, 2022 I bought a truck with a brand new pai speedometer in it and the idiot that owned the truck took it out of the box and put it in without calibrating it. I called the man I bought it from and asked if he had the paperwork that came with it and of course his answer was, We just took it out and put it in and then threw the box away, and in doing so, along with the paperwork. I was wondering if anyone else might have replaced their's with a pai FSP-0544 and might have a copy of the programming instructions. I know it's a longshot, but pai will not help anyone if you are not a distributor. Sad that you have their product and won't help anyone ! !

Onyx610 Posted January 21, 2022 Share Posted January 21, 2022 This looks similar to the one you have. Calibration is closer to the bottom. https://www.vdo-gauges.com/media/instructions/0 515 012 051 -- Programmable Speedometer(c).pdf Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted January 21, 2022 Share Posted January 21, 2022 so you have the 10 dip switches on the back of the speedo? I have the procedure printed out, when you respond I will try to post what you need.. also need to know tire size, 16 teeth on the output shaft of the tranny, and may need to know top gear ratio, probably around .76:1 .. The last one of these that I fixed, i used the book that I have and I put speedometer App on my phone so I could test drive and check it without have to pace another vehicle.. jojo Quote Link to comment Share on other sites More sharing options...
