so let say i have a blank ficm, and a ids 41 disc, how would i go about doing this? Thank you.

customer says he was getting better fuel economy before on his original calibration. It could be just the ulsd fuel. I figured if possible i could program it back and then he could see. If it made no difference then i would just updated it again. Vehicle is off warranty anyway.

Just wondering if there is a procedure to reinstall an earlier calibration in a truck which has been programmed to a later calibration. Thank you.
