ECM swap. What does it really get you? I am very close to doing this, meaning I have purchased all the parts but have not started the project. I am installing a Spearco IC and was told or I was under the assumtion that swapping the ECM with the IC upgrade would make the car run smoother and better. I am not totally into running a Scanmaster tool at the moment....... so should I wait or what?
Thanks
