has any one tried or know anything about the speedometer adapter from sean hyland to correct for gear and tire size changes?super ford put one on a 99 mustang but was wondering if it would work on our trucks.seems it should but i would like to now for sure.

 

According to Sal's site, his chip can account for speed differences from gears.

 

im aware of that but i wouldnt want to keep sending chips back every time i changed a gear.besides, i may want to use it on something else later.

 

This is a good question. Our tires are 28.5 diameter. If a person would go to say 31.5 is there any way easy or otherwise to correct the speedometer for the change in tire size???????????????????????????? Where are our tech guys.....What about those plastic tooth gears we use to change in the muncie four speeds. Do there transmissions have these?

I think it's all done via the computer now... Sal can program the eproms.. talk to him about a chip, and extra eproms if possible... different gear ratios could be burned into each eprom. And eproms are cheap, like 5 dollars or less I think..
