Smarty threw a code P0602. What does this mean? It had a rough idle. I also noticed a change in exhaust tone. Almost a miss or clap at idle. Cleared the code, still idled rough. set back to stock and reprogrammed smarty SW3 (60hp w/ timing)
One more quick ? what is the advantage of running timing?

 

You probably just need to download a new file to your Smarty.

See here: P0602

I had the same problem and the new download fixed it.

 

The 0602 code is normal for the older smarty versions....not a big deal, it's normal (doesnt mean anything....nothing wrong).....the latest update on the web eliminates the code.
