Tune help needed

[Waterloo]

First, where do you live?

And, you can do this yourself if you want, I did mine in the driveway a few years ago with some help from Unilever and Rawze...

You will need one of these... https://www.ebay.com/itm/Cummins-INLINE-...SwIJlZ9U~7

And a laptop, preferably running Windows 7. Windows 10 will work, but the Windows operating system is missing a few items that will need to be downloaded from MicroSoft to make the Insite software work. Nialo helped me with this issue at Rawze's house when we loaded a fresh copy of Insite and the other software on my MacBook Air in my Windows partition. And yes, if you own a Mac you can run a copy of Windows on it and Insite.

You should get the above no matter what, you will need this for any future diagnostics.

PM me your email and I will send you the instructions on how to do this if you want. It was not that difficult on the CM-871.
