HPTuners T87a tuning
So I have one of these tcm's on my 17 ats and have had the unlocking service done to it already from hptuners and am trying to access the tables on the car. Has anyone on this forum done this to their tcm yet? If so how did you get to accessing the tables?
I figured it was a new read all but that doesnt seem to give me access to the tcm |

You should come take a look at the I4 turbo LTG section of the forum. Several guys there have already done tuning on this TCM, and provide some great info on how to, and results from.

On my 2017 Camaro, after I got the TCM back from HPT unlocking it, I had to have my laptop connected to the internet when I read the TCM. I think it needs to 'phone home'. This was just for the initial read, once you have the file saved you should not need to do that anymore.
