Would any of the GuzziDiag experts here please tell me if that software can alter the target idle RPM without changing the map?

I've done a lot of very informative reading in the forum without finding an answer.

Background: I have a 2016 Stelvio with a good map installed by a competent person who's geographically inconvenient to me. The throttle body pivots are worn, causing stumbles at idle which are bad enough to stall the engine. New throttle bodies cost a bloody fortune and are on backorder even if I had the cash handy. Back when I worked at Hamlin Cycles, I learned to use PADS so I got GuzziDiag for home use and I am comfortable with using it for all the things that don't change the map, but I am reluctant (phobic?) to tinker with mapping.

Thank you, gentlemen!

You can change the idle target rpm if you open your map into a program like Tunerpro and change the  target value in the target idle table ,commit the changes to your map and install it into the ecu. Make sure and save your original map for reference should you ever want to go back .  there are different idle rpm targets depending on engine temp,

I'm sorry I misunderstood your question You cannot change the target idle with Guzzidiag , you need to modify the target idle map with a program like tunerpro

Also make sure your bike is set up properly first off. Valves adjusted, Tb's synched, TPS, and learn parameters reset, Make sure only one air bleed screw on the side  with greater manifold depression is open. If the tb bushes are truly that worn, I would try leaving both air bleeds closed . Seems odd a 2016 model would have worn out the pivot bushes so soon. Does the idle issue only happen when cold or does it do it even after warmed up?

A sticking stepper motor may be your issue too.

  Hey guys, question concerning fuel trim. I have a '09 Norge (2V) that I have installed a Beatle map. Bike runs very good but I have noticed the plugs are a little dark. Not black and sooty but not that nice light brown color. Do you think I can drop the fuel trim by a couple points ( currently set at 0)?

It won't hurt anything to reduce the co trim down to - 10 or so . any more than that and things will get lean at idle without modifying the map.

Why would your spend you life savings on new throttle bodies when you can re bush and re seal them?

If you're not living on the edge you're taking up to much room.

Does anyone know why the original post from this thread is gone? All I get when trying to view it is a period in it's place?
