Here are OEM Cummins Insite and Snap-On Pro Link Ultra in use. I can’t say because I have never used them. Bosch, CanDo, Texa and others may be better then the Pro Link software. The reality is no non OEM scanner will be better than a laptop with OEM software. I did notice Cummins 04 on the Ultra screen which is confusing because I though the software was mainly for 2007 and newer Cummins. Not saying Snap-on is the best by any means, but from playing with a Pro Link IQ and a Pro Link Ultra the software does most of the stuff that needs to be done. Paccar Davie software is $5,000 a year alone. Sure OEM will always be better in some ways, but multiple subscriptions can cost more then $5,000 a year. The older versions of Insite also had a flaw that indicate a throttle position sensor was faulty when it wasn’t faulty at all. Detroit OEM is also useless at times unless if you can change the password on the ECM which happens often on fleet trucks. A parameter that is locked can’t be changed with Insite either unless your a dealer. OEM Cummins Insite and Snap-On Pro Link Ultra, which is better? Opinions from Aubrey Lamon:Ĭummins Insite is better at some things, but I can tell you from experience OEM doesn’t mean you can change everything.
