I'm trying to correct a speedo for my friend that got lucky and bought her T/A with 4.10s

But don't know which Speedo Scalar value to change in the Constants tables. Any help would be greatly appreciated.

 

You don't have to use the scaler table. You can just click on tools and then speedometer calibration. Don't mess with the constants for your speedometer.

Yes, but there is no TOOLS section anywhere on this program. I keep telling people that. What's wrong here????
Using TunerCat w/ 94-95 EE and EEB Def Files....???

 

Yes,
I am using the EE TDF also. It is at the top next to the "Tables" at the main screen/menu. Same place you read/program the PCM.

Ok finally found the problem. Outdated Def Files. Got a newer version, but not the newest.

 

I've never had much luck with the speedo calibration in Tunercat.
Never seems to be accurate at all.
With my stock geared M6 with the stock speedo calibration, the rpms are about 400 different than if I use the speedo calibration stuff in tunercat. Still haven't figured out why.
How do you that have used this feature feel about its accuracy?

 

I'll find out soon enough.
