ISX15 CM2350 ECM Replacement Help

[ray417]

Greetings, this is my first time on a forum actually asking a question so please bare with me, while I start to understand how to navigate and where to post.

I have a 2009 Peterbilt with an ISX15 that I recently had great success rebuilding inframe thanks to the videos posted by Rawze, Thank You!!!....it was my first!

My current issue is the ECM is bad, sometimes it starts sometimes it does not. A light tap on the ECM will make fuel lift pump come on and truck will start as well as if running the throttle pedal will work then not. Of course this is a de-mandated truck in which the de-mandate has been working outstanding for 3 years now.

How can I save the current ECM calibration and parameters and install them in the new ECM. Current electronic tool is Cummins Insite with a current subscription on a dell laptop.

Thank you in advance!
