Quick question

[mr_bots]

When I got my Sierra done the process went like this:

Paid and put my deposit down towards the tune. They sent me a new ECM (engine) and TCM (transmission) with instruction on how to do the security relearn. Did the security relearn and then a while later drove to the meet. When I got to the meet Justin asked a few questions, did the crank relearn and we drove around a bit while he tinkered with some more stuff. I kept both sets of computers so I could throw my stock ones back in if I needed to go to the dealership to retain the 5yr/100k warranty.

My dad got a data logging tune that just required driving around with my laptop and then e-mailing the data to Justin. He then sent new modules down to put in the truck and the software used for the data logging can also perform the crank relearn.

They include all the instruction that you might need

Also, FYI: if you have the 6 speed auto the TCM is in the tranny and can't be swapped out but if you do an in-person tune he'll just reprogram that one.

A good tune, such as Black Bear is the best money that can be spent on a GM.

I am still irritated that I didn't get to meet up with you after you drove all the way to Wichita and I was busy with work

it happens

Thanks for the info Matt. I was worried about driving around with the new ECM. So you dont need to do the crank relearn till the tunes I assume?

You need the crank relearn after you switch modules.

Alright thanks for all the information fellas. I'll be able to sleep a little better now.

Also, driving around without the crank relearn won't hurt anything, just throw the cel. Like daddy stated, if you keep your OE modules you shouldn't even need the relearn.

Do I have to send my ECM/PCM in before my tune? Or can I give it to yall at the time of the meet?

If you are getting an in person tune, you do not need to send in your ECM as Justin tunes it on-site.

However, if you would like a spare ECM (one for Justin to tune and one to keep stock for when you go to the dealership, etc), you need to purchase the spare ECM prior to the in person tune. If you purchase a spare computer, we will perform the crank relearn on all 99+ vehicles.
