Want to get some custom tunes for my sct x4. Turned on the tuner to get the strategy code and it says no ECU code.

Not sure what to do. Truck is a 2006 6.0.

Back in the summer my Ficm voltage was low so I pulled it off and sent it in to ficm repair. Got it back and everything was great. Now when I did this I am not sure I put the stock tune back in before removing it. Is this the issue and if so what is the fix?

I am able to put the can tunes in and back to stock no problem.

Hope someone can help.

Thanks in advance.

 

If you're running those canned tunes, you need to return your truck to stock before the strategy number will show up.

 

I think I did that when I went to the default setting and changed the tune. Is that correct?

I didn't drive the truck after that, just changed the tune in the driveway.

 

There is an option before the tuning options that says "return to stock." If you have done that right the marry to the tuner will be removed and then you should be able to look up the ecu strategy

 

You were right. Thank you so much for your help.

No way could I own this truck without this site and the people on here.
