Alright guys I’ve run into an interesting issue, I forgot to save my factory ecm file when I first done the tuning on my truck. Ended up finding another file so I could have a spare to work with. I did however save my trans file but on the speedo parameter my trans has the final drive ratio as 4.10 and gear ration as 3.73, the file that I am using has the final drive as a 3.73. I guess what my question is do I need to change it to match my factory trans file before putting the new tunes on or should I read the trans one more time just to verify that what’s in it is correct? Noted: I haven’t done anything at all with the trans tuning and also in the pics the first table is the file I’m using for my new tunes and the second is my factory trans file. Any help would be appreciated.
