View Full Version : Isx cm2350

Hello. I'm looking for a factory file from a ISX CM2350 600/1950. I want to make sure my RV has the factory calibration in it before I make any changes.

Thank you in advance.

Normally you would just read the ECM and keep that file as your stock tune.
From my experience there is countless variations of tunes in the CM2350A ECM, you would have to provide the E/C number printed on the ECM as a starting point if you can't read it.
