8.3 ISC Tuning

[nosgsxr]

New to the form and have been looking around but not sure where to start. I have seen several names on here but not sure if anyone is better with the Cummins than others. Can anyone point me in the correct direction for help with a tune for my 2011 8.3 ISC ( it still has the DPF junk on it) in a motorhome?

Many things can be done to the engine file once its copied out.

I don't want be there. Do you know if I buy the amazon/ebay data link adapter and software will i be able to pull the tune and send it t where it can be looked at or adjusted? or will it just be a tool for diagnostics? I'm not familiar with this set up always used the auto side of stuff like HP tuners.

If you buy an inline adapter you can use it for both diagnostic's and copying the program out of the ecm. You'll just need the proper software to go along with it.

Insite for diagnostic

C a l t e r m for copying the file out.
