2005 Silverado SS Speedo Change?
I had a question on changing the speedo for larger tires. I setup for Modify Stock Tune. In the menu I selected adjustable parameters/actual wheel size. Punched in my width, aspect ratio, and wheel size and then save. Saved the tune and exit the ECM. Just to double check I went back to the same menu for wheel size and it is asterisked as it should be but when I go to the data it says "not set" Am I missing something in respect that it is already sent but the tuner just doesn't show it for that session? I would assume it should show my last saved values from my tune. Also the tire height menu shows 36" even though I'm running a 30" tire. Even after I make my adjustments. :banghead: Thanks for any help
