Hey guys, I’ve had my s1025 kit installed for a while and there have been recalls and ecm updates since the kit was installed. I’ve always had my local dealership pause on the updates because I didn’t know what would happen.

Are there any other Livernois package owners who have had updates done safely? Any recommendations about what I should do?

What does the recall / update fix?

 

[duffner]

It’s been a while since I’ve last remembered but if I remember it was a transmission reprogram

If you not have any specific issues and are happy with it, I would leave well enough alone...…...

This for sure. Keep the TH away from the dealers unless absolutely necessary.

I would not let dealer flash my trans or motor specially if you are having no issues. Call livernois and ask them though dont listen to us. seriously when something goes wrong your gonna call livernois so get their advise.

Last I was in the dealer, they asked if I had any special programing done to mine, I told them no, so the service advisor asked if it was okay to flash a trans update, which I said no problem. I asked what it was fixing, he said something along the lines of shifts not happening correctly at low RPM's. I would assume, given you're tuned anyways, having a dealership flash anything would not be good.

Do not let the dealership flash your Hawk like others have mentioned. Your transmission already has a performance tune to match your engine package that you don't want to loose.

I have the same s1025 kit and have talked with Livernois about this. Your engine PCM is now on a different operating system as Livernois developed their own OS for their tunes and more specifically their flex fuel tunes that the dealer very likely cannot get into the bootloader to update the PCM anyway.

But if they could and did overwrite your PCM tune you will have a useless vehicle you cannot start or drive now as the stock tune is not calibrated for the much larger ID1300x injectors and you would be filling your cylinders with way too much fuel. So now you either have it towed to your house or push it in a corner and leave it at the dealership. Then you would have to pull the PCM and send it back to Livernois to have your tune reflashed before you can start your Hawk again, at a cost of course.

After all that you would have to again get a remote transmission calibration tune from Livernois from either their shipped laptop or you would have to buy their new My Calibrator touch controller (again at a cost) and reflash the transmission yourself with a tune they email you.

Keep in mind that this is all dependent on when your PCM was tuned if this option is even available to you or not. Mine was an early 2018 s1025 build so my PCM will not accept local tune updates from a handheld device as they did not exist back then. I would need to pull my PCM and send back to Livernois to get their latest OS uploaded to accept tune upload from such a device.

This is the route I am going to go (purchase a my calibrator touch) very soon once I stop driving my Hawk for the winter months. I want the ability to upload emailed tune updates myself and use the My Calibrator touch as a data logger (like many do with a Diablo device) all without a need to carry a laptop.

Sorry for the long answer but I have been talking to Livernois about this topic recently.

I’ve got a S1025 PCM and a few other things in the garage if anyone needs one.

I think I am going to get the calibrator also.
only reason I have not already got it is I want my guy to come out with a flex tune if he does I will jump ship. I just like the flex tune way to much its perfect for me

There is a trans flash to address low speed issues and also a cruise control issue flash for 2018’s.

I don't know what kind of tune you have but mine cranked me up to about 950 horsepower and if they would flash the computer they warned me it would take the tune off the car and the motor could blow if the car is hammered. You may want to check into the repercussions of having your computer flashed by the dealer.

Sorry everyone for the lack of response! For some reason, all of my forum updates went to spam!!! My local Jeep dealer has been awesome, for what it's worth, they have been super helpful, and even considerate of everything that is done to the vehicle. They even kept my warranty. I'll need to get the calibrator at some point, as I have ECM updates to make outside of the Tune based ones for other electronic-related things. @Double G, did you end up getting one? I'm thinking about it now myself.

Yes sir, I have the MyCalibrator from Livernois now and it works great. 👍 Over the winter I pulled my supercharger to install the thermal blanket and thermal spacers underneath. While I had everything appart I had Livernois do their CNC porting of the snout while I installed a Kenny Bell dual BAP, custom Zietronix flex fuel sensor/gauge and custom polished the supercharger, snout, throttle body and Livernois CAI.

Since I needed a new tune for the BAP anyway, and wanted the current Livernois "s1025" tune updates/safety features, I did have them update the OS on my ECM and purchased the handheld MyCalibrator device.

I simply registered my device, up loaded my stock tune for backup and downloaded my new updated BAP s1025 tune via the internet. Connected the handheld tuner to the Hawk and quickly uploaded the engine and transmission tune from the handheld device.

It also reads/resets codes, does data logging, displays gauges and provides some diagnostic tools. Best one was the ability to turn on/off the supercharger coolant pump without the engine running so I could purge air from the supercharger after I reinstaled it. 👍
