copy ecm file

hello all

how can I copy my ecm file to laptop with efilive and make adjustments? it is a custom file on ecm now but my programmer is no longer in contact.

I need to update my gear ratio setting from 3.42 to 4.10 and also adjust the lockup converter settings

I have an mm3 programmer and file now.


thank u

Your tune is likely locked, so even if you copy it you will not be able to read or edit.

You have a CM2350, the file on the ECM cannot be read out.

You need to find yourself a suitable base file to start from.

What do you need to update due to gear change? The speedometer should automatically update. At least it did on the last fourth gen I did a gear swap in. The gear ratio does not reside in the PCM, if it does need changed, get a Hypertech programmer that will allow you to change tire size and gear.
