When you guys send you ecm's back in for a retune how do they usually like it handled. Do you just put a note in with the ecm what you want changed and throw the shipping fee in there also? I have never sent mine back in and just wanted to make sure I didnt screw it up.

 

when I paypal'd him, I sent enough to cover return shipping as well... as far as your specs, I'd type them up, print them out and include them in the box with the PCM. I like to type them so there's no questions on the parameters... my handwriting sucks

 

i think you tell him what you want changed via computer/phone... he has on file what he tuned for you...

so he can just send you a new pcm, you paypal him the shipping for it or whatever payment for it... and than when you get it, install it, make sure everything is right, and than send back your old pcm... he does this so you dont have any down time
