Well being an Electromotive guy this will be the first time I will ever try tuning a factory ECM. I just bought a hybrid car that has an LS1 in it and the PO gave me the EFILive that he used to tune it. My question is can I connect the laptop directly to the OBD II port with a proprietary cable or does it have to go through the handheld? I will obviously have to purchase something since it doesn't look like he gave me all the pieces ie; cable or handheld.

Thanks for any info.

Joe
