You definitely wouldn’t be able to use the T87A file at all since it’ll have a different OS. But no reason you couldn’t do a “compare file” and copy changes to the T93 file.

Yes exactly. I compared and copied everything over. What’s weird is I can flash the stock T93 file but the copied file won’t. I’ve triple checked the file idk what else it could be.

So you can't modify the T93 TCM you sent in and had unlocked? You can't up the shift pressures? Change the torque levels from stock? Maybe I'm misunderstanding what your saying.

Did you buy the credits again? New module, more credits...

At this point no. I have taken the stock file and tried making just 1 change to the file and it writes fine and shows completed but after it finishes and I push start button once I get a message saying put car in park and the only way to get it to go away is unhook the battery. If I reflash with the stock t93 file with no changes it’s fine. It’s very weird.

Yes new credits. It won’t even allow you to start to write the tcm the first time without the 4 credits. I can write the tcm with the stock file over and over again. The minute I make any changes whatsoever and try to write it I get the put in park screen and everything freezes.

Is your laptop connected to the internet while doing this? Just trying to cover all the bases.

Have you went on the HPT website to the forums to see if someone has an answer. Since I'm using the same T93 that came out of my car and haven't had the T87 unlock as you did maybe mine won't do that. I'm really leery of the unlock now. Hope this didn't turn out to be a waste of money, hopefully you can get with sales@hpt on Monday and they can help you figure this out.

I'm assuming the car was in park and battery disconnected when you removed the T87 TCM. This is very weird and would seem like it has something to do with the T87 that was in there before. Did you just read the T93 when you put it back in or did you read all? DId HPT send instructions on the re-install?

Yep connected to the internet. Latest update on HP tuners. It actually shows that it flashed and get the complete stays after. It when I got to cycle key after that I get the put in park and everything locks up.

Yes car in park battery disconnected for TCM install. I read the tcm after install and all was fine. I can flash the stock file but for some reason if I change anything at all I get the error.

I have reached out to hp tuners support but haven’t heard anything back yet.

I double checked plug on tcm it’s installed correctly.

Like I said it’s crazy because it will flash stock file with no issues it once I change anything in tune file that I get the error.

Thank you. Will update once I get answers. I did have the T87A so not sure if that has something to do with it or not? I’ve tried flashing tcm/ecm both and tcm alone and still get the put car in park.

This is with the new MPV3 too.

Interesting. I never got the instructions emailed. However it’s the stock tcm from my car, I sent it in for unlock. Idk if that matters or not but I will try these steps and see if it works.

Thank you

I think that's for replacing with another TCM, I think.

[laynlo15]

Now I'm wondering if you needed to do the replace tcm. Went back a read it again and even though it's the original T93 it may be that the T87 is the issue as it was the last TCM in the car. Not sure on this but I may be the issue. It also appears mine with just be a matter of putting the TCM back in and should be ready to tune. I don't even know if I'll have to read the file, it does not say that on the website. I guess I'll find out when I put it back in its place Tuesday. Geezzz.

After the TCM arrives at HP Tuners, an HP Tuners engineer will unlock the TCM so it can then be licensed, edited, and flashed with HP Tuners software. This is a one-time unlock that will not affect other operations of the TCM. The factory tools will still work for service and HP Tuners will then work for tuning.
Once you receive the TCM back from unlock, re-install the TCM back into the vehicle, and then you may tune the TCM with HP Tuners’ VCM Suite BETA by licensing the TCM for (4) Universal Credits (sold separately).
