Default What is your WOT shift point rpm?

I got my custom tunes today and was going threw them and the WOT was 4500? I thought it was supposed to be 5000. Maybe im wrong.

You think we can get better 1/4mile times shifting at 4500 or 5000. I always ran myne at 5000 before. But maybe thats not whats best. I know the 5.4l really starts to fall off around 5k. Insufficient flow in the 2v heads.

Just curious

Thanks

I'm sorry, I don't understand what you are saying. There are three different WOT shift points (1-2, 2-3 and 3-4) and there is a Max RPM (Rev Limit) that apply here. When you say 4500, it means nothing to me. What does this apply to?

my 1-2 shifts and my 2-3 shifts are set to 4500 rpm instead of 5000 rpm at WOT.

In the custom options, the programmers uses the default values in the stock calibration for the base option values. This, unfortunately, means that the values you start with have no relation to the values in your custom files. This only applies to modified custom options. Anything you do not change will still use the values in the custom file.

For reference, the WOT shift values are 5200, 5200, and 4700 for the 1-2, 2-3 and 3-4 shifts, respectively.

Take care.

OK, this seems new to me. Possibly, it's an artifact of the earlier model Gryphons? I know in mine (04+ model) when I opened Custom Options, it seemed to show the values YOU put in for my custom tunes Bill. And, they were slightly different for the towing and non-tow custom tunes, which further suggests they were values YOU entered and they were in the 5000-5100 range I believe for 1-2 and 2-3 and maybe 4400-4600 for 3-4.

But, you seem to be saying here, Bill, that Custom Options are going to pull the stock shift points up in his Gryphon which would then replace the ones in his tunes if he did not change them?

I keep learning things about the Custom Options that I don't like!

Ahh okay, then that brings up one question. Does the fuel mapping and timing stay the same for my custom tunes when i customize it farther myself? Shift points/firmness/ tire size/ timing advance?

Thanks Bill

Jack,

This was a common complaint with the early hardware Evolutions. The later hardware (new processor & updated firmware) only exhibit this issue if you do not proceed through an initial programming session first. In such a case, it uses an arbitrary value instead of values from the tuned calibration itself.

Kyle,

Anything you do not change stays the same. Also, since most options are adders, it will simply add a value to the modified calibrations. The only time there is confusion is when changing a specific value such as WOT shifts, Tire Size, or Gear Ratio. These values may not directly reflect what is in the custom file but may instead use an arbitrary value.

I hope this makes sense.
