Heh. Wouldn't you like to know
Im not an excel expert by any means, but this is something that I threw together today using Josh H's calculator. Im sure it could use a BUNCH of improvement, but this is just what i have. Hope it helps some

Its a basic timing calc for the LML. Should make things a little bit easier. lol Maybe Josh or someone can fix any problems with it, if there may be any. :thumb:

Here is a excel calculator I made to get my LB7 to shift good. I haven't used it on any other trucks so let me know if it works for you.

i have another for the LLY that i will have to dig out and post up

2004LB7,

Not to nitpick. Found another error. On the LB7 & LLY in the Base Torque tab, you use the same cell that references the 90mm3 to also reference 100mm3. Fixing these small errors seems to actually make it work quite well. Ill double check to see if there were any others that I had found.

Here is some other calculators I have created with another member on here but haven't had anything to test them on. use at your own risk

The one I would most like feedback on is the defuel calculator for LB7 & LLYs. if anyone wants to try it out and give us your opinion I would appreciate it

I thought we were always told to stay away from touching defuel
unless you know what you are playing with and understand the tables in great detail, its best to not mess with it. you can start killing the trans in a hurry if you just go shoving numbers in and testing it out in the truck.

WOT defuel is the one to really be careful on, part throttle is usually overly aggressive the moment you start adding in more power so there is room to mess with it IF you know what you are doing in there. small changes can make a BIG difference and you need to run the truck for a little while and log to see how it learns in.
