Can I reset the gear ratio using my trinity?

Not at the moment, but we can do it for you in a custom tune if needed...

Ok I how do I get this custom tune I have not installed my trinity yet. I have a 2008 Chevy Silverado crew cab 5.3 4x4
also when I plug the trinity into my computer is it not acknoledgeing it.

Sounds like you need to install the Trinity Driver from the CD.

I have the trinity working with my PC now. I need a custom tune to adjust dsettings for a gear ration change.
I have a 2008 silverado 5.3ltr I have changed my gears from 3.73 to a 4.56 gear ratio. Can you please send me a custom tune. I have not installed my trinity yet do to waiting for this tune.

you have to install a tune from the trinity, so that the trinity saves the copy of the original backup tune file to it...

then you need to use the latest version of the DSDownloader app (2.2.1.7.) and export the copy of your original backup stock tune file, and also a copy of the "last tune written" tune file...

then post up those two tune files...

Ok so I need to tune the truck first then paste a back up on here?

yep

Ok I have programed my truck, I have down loaded the stock tune, I am unable to cut and paste it though or copy and paste. How to I get the file on here. Also I need help with the speedo settings, I have 35 x 12.5 x 20 tire size I do not know this equates to in mm though or aspect ratio please help. I tried setting by tire size but it did not help. Im not sure if this is contribuyed by the gearing change.

ok I think that will do it, please advise on tire adjustment from post 05/31/10

Ok are you guys working on this, I only bought your tuner because you said you could do a custom tune for the gear ratio. I am no longer getting responces from you. I would really like to get my spedo right as it is racking up extra miles on my truck and effecting the over all milage.

sorry...we'll need a copy of the last tune written to the truck as well please.

Ok how do I get that I used your standard tune with out changing any parameters. Also back to the tires I need to know the correct formula for inputing for a 35, 12.5, 20.
