Predator gear ratio tuning

[smueller]

Does it matter if I have an Autometer gauge cluster in my car? I used the Diablosport Predator to change my gear ratio to 4.10 and then installed the tune. It said the tune was installed, but when I went for a drive the speedometer was still off. What gives?

i thought you had to install the tune first, then modify it.

I'm not exactly sure. I read that book like twelve times and it does not seem very helpful. I used the basic HP tune and changed the gear ratio before I installed it. I thought that is what I was supposed to do. Correct me if I'm wrong...

no, it doesn't matter.

 

[smueller]

And why does the gear ratio say 4.09 under the options to change gear ratio? Shouldn't it be 4.10? Am I missing something...

Extra gauges should not matter.

Change the gear setting in the Predator, then flash the tune into the car. 4.09 is good.
