I am new to efilive and im having a couple of problems. The problem that i am encountering is i am able to download the info from the trucks ecm but i am not able to upload any changes that i have made to the vehicles ecm. The vehicle that i am attempting to tune is a 05 LLY 2500 4x4 D-Max we also have an 02 LB7 2500 2x4 D-max and i am having the same problems with it. These trucks are sponsored by Wyotech and either one might become the Wyotech drag truck. so if you have any info please let me know.

Thanks

Colin
