Grand marquis speedo reprogramming
I have a 96 grand marquis ls with the digital dash and I would like to swap out the 2.73s for 3.55s how do I reprogram the speedometer?

Gear Change ??
No reprogramming necessary --
Your 2.73:1 to 3.55:1 gear change requires a 21-tooth speedometer gear. That's it. My question is: WHY in hell would anyone do such a gear-change on a 2-ton sedan !?? What benefits do you EXPECT from the gear ratio change ? I mean, even with the gear change, some girl in a Camry V-6 will probably leave you flat in your 2-ton, 4-door sedan. But hey, give it a go and tell us how it went. ;>;) https://cimg3.ibsrv.net/gimg/www.mer...d742955f66.jpg Dual Exhausts = Walker H-Pipe; MagnaFlow 2" x 21" Glasspak Mufflers; Walker Tailpipes; Superior Tips. |
