2014, 5.3L, Silverado tire size change
My father in law has a 2014 High Country Silverado, 5.3, 4x4. He went from 265/65/18 to 265/70/18 and I'd like to correct his speedo for him. I've corrected a number of speedometers on LS1B vehicles but never something this new. I don't want any issues partly for the obvious and partly because we're in Maine and he will have a 12 hour drive home at the end of the week.
Just looking for any clarification on this. Does it work the same as the older vehicles? Simply use the speedo correction tool and apply? Will this adjust shift points or just the speedometer?
Thanks!
2017 Silverado tire change?
I "helped" a buddy adjust his speedo on his new 2017 Silverado 1500 for his 35's. Dealership put the lift and tires on, but did not correct the speedo. I thought it was a little strange and chalked it up to incompetence, but then again appearently so am I.
As a result he no longer has cruise control. Specifics
EFILive V2
V8 Version 8.2.5 build 316
V7.5 version V7.5.10 build 323
OS: 12677878
Controller: E92
I purchased a controller authorization code to read out the stock calibration and changed parameter H0105 from 405 to 364 within 7.5. Then performed a full-flash with V8. I saved the stock tune, modified and saved the tire size correction as a different file.
Should have I adjusted H0136 by the same amount?
