What is this suppose to plug into?....also I know I need to do download to get my base but in the mean time I was messing with things and I used to have 10 power settings...now I only have 4....what’d I do wrong?

Thats the egt gauge. 

 

we can't answer you level question until we know what you are running on the box and what vehicle profile you have selected. 

 

The revision on the box under the hood must match the vehicle profile in the app. 

 

If you have V2 under the hood you can run V2 vehicle profile.   If you have the older ADR1000/2000/3000/beta tunes then you cannot use the v2 vehicle profile as none of the tuning variables match.  

 

Mixing and matching will cause all sorts of weird issues.

So I gotta do the download....thanks
