My evolution tuner is about 2 yrs old now and I haven't updated since the initial install. I just went to check for updates and noticed that there are quite a few. Here's the dumb question: Do I have to load each update or just the latest?

 

It will just use the last update.

 

Latest. The newest versions of software always contain the base product +/-the new stuff. Can't imagine this working any other way.

 

I believe just the latest.

 

Thanks guys. I started to do each update individually but soon realized that was going to take quite awhile. I am having some difficulties with the tuner now. I updated the latest versions (20 & 28) and I'm getting some f1 error codes. It wont let me do any custom programming for tire size and gear ratios. Any ideas on why not?

 

The latest version is E3.22.28. If you are only at E3.20.28, you need to update further. If you are still having problems after 22.28 call me and I'll see what you've got going on.

Take care.
