im asking because my tack is currently unavailable right now

anyways, with a 4.785 gearing, at what mph does each gear reach redline at 8400rpm?

im asking because i want to use my speedo for my shift points since my tach is not available at the moment.

8400rpm 1st gear = ? mph?
8400rpm 2nd gear = ? mph?
8400rpm 3rd gear = ? mph?
8400rpm 4th gear = ? mph?

 

You can look it up on this Excel spreadsheet.

You'll need to change worksheets (using the tabs at the bottom) first, since the first worksheet shown is for ATS gears, not the stock gears. Click on the "ITR" tab for the USIM stock gearing. You can change the ratios on it and see the effect on the numbers. Or, use whatever tab corresponds to your gears if you have one of the other setups.

Sure, just change all the formulas, as follows:

1. Hit CTRL-H to do a replace.

2. Find what: 1050
Replace with: 652.44
Click "Replace All"

It should say that it made 355 replacements.

3. Repeat for every worksheet.

You should do the same thing to find the text MPH and replace all with KMPH so the column headings are correct (5 replacements per worksheet).

 

thanks, your a genious
