I'm looking to change my rear end gears to 4.10 and i tried setting that on my trinity but it will not let me select the new gears. it will let me set it to 0 1 5 or 6 thats it.

hmm...there should be a fine and coarse adjustment, try the fine (single arrow) adjustment and see if it lets you change it to what you need.

Thanks

post up the last tune written and the backup for now and we'll make you a custom tune to fix it.

Thats not what Mike wants. He's gonna make you a custom tune. Export the Last Tune Written off the Trinity and post that.

yeah... that's the data logging gauge layout file... you need to use the dsdownloader software and Get Tune File From Tool... and get the original backup tune file, and then do it again and get the last tune written tune file... then post them up here...

I have a suggestion that will work. First, you will need a gps to give you an accurate speed. Select whatever ratio is closest to what you want. GM uses a 41 tooth ring gear and just changes the pinion. (4.10 = 10 tooth - 3.73 = 11 tooth - 3.42 = 12 tooth) They have been doing the same thing on their light trucks and performance cars with rear wheel drive since the 60's. (Anyone remember the 12 bolt posi's?) Then select a smaller diameter tire than what your really using until your speedometer registers the same speed as the gps and then you have it. It really doesn't make much difference what numbers you use to get the correct speedo reading. What matters is drive shaft revolutions per tire revolution.

make sure you RESET ALL PARAMETERS when you select this tune to install it... because all the other changes you made yourself before are already in this custom tune file...
