Looking for MG Service Shop in Seattle/Portland Area

[RonStelvio]

I have a '09 Stelvio that needs help with a snatchy throttle... snatchy to to point it's not rideable.  I was fine last year but not now.  I will need a tech that's familiar with PC3 (Power Commander 3).  The roller rocker update has been done.

Do any any of you have a MG proficient shop recommendation?  Independent is OK.

As I live in Olympia (South Puget Sound area), going to Seattle or Portland is ok.  I can trailer it as necessary.
 
I have been unable to get in contact with Jason Wallace of DenizenMoto.  I also tried to reach him through WildGuzzi.

  Have you considered just disconnecting the PC3 and see if that improves anything ?

PC3 doesn't work on a Stelvio, it should be a 5 or 6 with autotune, Tod over at Guzzi Tech has maps. Disconnect the PC. Check the play in your throttle cable & adjust it to almost no play. I used to set up PC5 & 6's for customers at the shops I worked at here in GA
There are Power Commander centers up there but most likely not a Guzzi dealer. Before you can tune the PC you have to disconect it & tune your bike 1st

Best option is to bin the PC 3 and install a Beetle map.

What Dave says.  PC3 is made for earlier ECU's not 5AM like Stelvio has. Best to put a map in the ECU that works not an add on tool.
I have installed lot's of Beetle maps and one's from GTM, I have to work with whatever the customer wants.

The bike still has to be tuned properly BEFORE anything else!! When was the last time the TPS was reset, Valves adjusted, throttle bodies cleaned & adjusted?? An add on tool does not fix that.

[RonStelvio]

I should have mentioned that I installed Todd's map in the the ECU back in 2017. 

My memory is fuzzy on the details from so long ago, but I think I added the PC3 after installing Todd's  map to address the low RPM fueling.  I also had an incorrect impression that the PC3 would auto adjust like a cars FI... I should have done more research.

So the plan:

• Adjust the throttle linkage.
• Bypass the PC3.
• Remove the PC3 based on the results of #2.

I don't know anything about a 'Beatle' map.

If Todd put a map in your ECU it should be the Race Map which works fine with out a PC. PC3's do not work with your computer it would be a PC5 or 6 that work with an auto tune separate box. Auto tune makes the adjustment suggestions and you have to upload those into the PC5/6
Beetle maps are like the map Todd put in your ECU, just made by someone else and don't need a PC to readjust.

To tune your bike properly the PC has to be disconnected, after tuning you hook it back up. If you have a PC3 it does not work with a 5AM ECU, that may be your issue. You would need a 5 or 6   I would contact Todd for more info

I've had my bike serviced at Optimum Performance Motorsports in Portland and they were a good shop. I'd recommend calling them to check if they're equipped for and familiar with that Dynojet Power Commander though I suspect they would be. They also have a location in Redmond, WA.
