With out any additional info I am assuming you are swapping from stock 3.45s.
So your speedo will be fast by about 13.3%. You speedo will read 13% faster than you are actually going. It may help you not to speed, but will also rack up more miles on your car.

MA2010SS · 05-04-2012, 01:01 PM

Speedo will be about 5mph faster than your actual speed

Same problem after my gear swap on of the rear wheel speed sensor was bad....$14 dollars & 1bolt and all good. The gear will only throw the speedo off shouldn't be lights.

More misinformation.

When your speedo is off it is off by a percentage, not by a set number. If you change your gears by 10% then your speedo is off by 10% At 10 mph it will be off by 1 mph, at 50 mph it will be off by 5 mph, at 80 mph it will be off by 8 mph, ect. As you can see you can't just say your speedo will be off by X mph, unless of course you say your speedo will be off by X mph at X mph.

I had a friend do some work on his car and when he finished he had lights all over the dash and was worried... So i climbed in his car and started it. Problem solved.. LMAO. Its probably nothing major. make sure you're reflashing your car correctly and burn up the road! :-)

Question for you, why is it when I took my car for a ride before adjusting the speedo the car was consistanly off by 7-8mph accord to my gps (3.45 to 4.11)? Now granted I did only get the car up to 50 mph but if I was doing 30 (GPS Speed) the car was showing 37-38, same number if I was doing 50(GPS Speed)

I adjusted the speedo after 8 miles or so and have not touched that part of the tune since

So you are telling me that when you were standing still your speedo said 7-8 mph? At 1 mph it said 8-9 mph? If when your GPS shows 30 mph and your car speedo shows 37-38 mph and at when your GPS shows 50 mph your car speedo still shows 37-38 mph , then it sounds like you have a crappy GPS.

This is simple math. If you increase or decrease your gear ratio by any percentage, you will inversely change your speed by that same percentage. Numbers don't lie.

MA2010SS · 05-06-2012, 07:06 AM

No, I noticed the speed difference at 30mph and again at 50mph there was a 7-8mph difference both times two times when I was at steady speeds is when I noticed, I was not looking for it the number was the same as far as the speedo being off, again I did not go over 50 until I changed the gear ratio later that day. Maybe I do have a crappy GPS

Well going to 4.11s your speedo will be off by 19.13%. So when you are going 30 mph your speedo should show 35 and when you are going 50 mph your speedo should show 59 mph.

MA2010SS · 05-06-2012, 07:57 PM

Gotcha on that, next time I play with the tune I will change back to 3.45 in the tune and for sh!ts and giggles see if that's the outcome and pay more attention

*UPDATE* So i went to the dealer and ordered the left side speed sensor, changed it out and good to go!! So how the little wire got damaged inside, couldnt see any damage but that was it!! Thanks for all the info!!

The wire is very thin and delicate. Most people don't unplug them before messing with the rear suspension. The plastic sheath can stretch but the wire inside can't and it breaks. I see people do this ALL the time. I always unplug them when I do any work close to them, just to be safe.

We did the diff swap to 3:91 on Saturday.

No light show in my dash after the swap. The speedo is out, but that's it.
