Do the Speed/RPM graphs update when you change the data? Not seeing it happen.

You probably need to "enable macros" or similar...

Sorted the problem. I copied the whole sheet to a new one to have comparative sheets for dirfferent Isuzu 5 speeds and the graphs lost their linkages.

Here are a couple of gear split charts for an Isuzu engine, 3.55:1 diffs and 4 or 5 speed trans. Note that the NA Isuzu won't pull theoretical top speed, 3200 rpm in top.

Hi Ben
First chance I've had to check the transfer box. Its a 28D with "E" suffix so likely 1.222:1 with 26 teeth on the input gear.

I guess l'm lucky for once!
