This is not a new trick but most guys don't like to solder boards so I thought I'd offer something back for all the help I get here.

If you want your speedo back to correct after changing gears or tires here's the way to do it. You need to find this piece under your dash, unplug it and mail it to me, I will solder in the dip switch and mail back with instructions how to set dip switches for correct operation for $40. If I have spares which I do now I will mail you one with an additional $25. core charge refundable upon receiving yours.



If you have a newer vehicle it has a similar device called a VSSB. I have them too. $50. plus $25 core includes shipping.


If you are going to tune your ECM and want a flash chip installed in your ECM I can also solder them in for $40. plus $10. shipping. Then you can use the newer flash EEPROM that can erase with a click of mouse instead of needing a UV eraser and still be very unreliable.
