I am working on a 4.8 2007 Silverado. Installed a new camshaft and some bolt ons. I have been working on the tune. Got my Maf squared away and have been working on my idle. Well it's December here in SC, so I didn't notice at first, but for some reason my fans will not operate now. I didn't change anything in my tune at all under the system tab yet. I compared it to my baseline tune I pulled. The factory tune calls for 43% at 217.4*. I watched via VCM Scanner and etc crept into the 220* range. I can command electric fans on with the scanner, but the tune will not command it(well, I cant say it's actually not commanding it, I don't know how to watch the outputs in real time, if that's even a thing.) Any help would be appreciated.
Attached are the baseline and newest running tunes. Could this be related somehow to how I wrote the tune to the truck? Should I write all instead of write calibration?
