Part 4: The J1.2 Powertrain

[prj]

Knowing that it’s impossible to exceed the stock 640 Nm without the Prj fix who add only 20Nm, I don’t understand how Shiftech can claim to produce that much torque…

This is really in the wrong thread, as it's not J1.2, and they can't flash J1.2

For J1.1 there was a protocol released for cars up to 06.2023 today from a public flashtool (the protocol was private before), so you should see a lot of offers now online.

Of course none of them have done any R&D. The launch patch is not possible and cloning ASG is not possible (because this tool allows to only write the calibration area, not the code), so the cars will be flagged at the dealer and there will not be any more torque on most cars.
However, the approach from most of these companies is to claim they can do everything immediately, and market fake numbers, even though they have never done anything before, and then experiment on the customer car.

The smarter ones will copy our numbers from the website, the more silly ones will just claim random numbers, as you see here

TL;DR:
It's a scam.

Technically, they could purchase a new ASG unit and flash it instead of modifying the original one (fault codes cleared and FoD ignored with workaround in the calibration), or need to code anything else ?

PS: Was WoT Engineering the only company that had access to this protocol privately through Autotuner, while other companies like yours obtained it through independent R&D ?

You can not "ignore FoD through calibration", there are multiple hardcoded checks, it does not work correctly. Parts of launch control don't trigger (even if it shows on the dash) and other issues. I am of course not going to tell you exactly what, have fun finding it out while bricking a few controllers

Not the only company. But ask them about cloning the ASG - they did not offer it because they never got it to work properly.

It's clear who did own R&D because we can flash J1.2, also remotely.

This situation is kinda funny - the first question we always get is about the warranty. But as always in this business, everyone can just lie to the customer. About power, about warranty.
Of course the customer is then on the hook for an extra 15000-60000 EUR depreciation of the vehicle when Porsche Approved is not extended or service under it is refused - and this is forever, as the car is flagged permanently. So was the tuning cheap then?

Thanks for all your replies, you’ve built a head start that will be hard for others to catch up with. Your real strength lies in your full-stack approach, your deep research capabilities, and the clarity of your explanations… even when dealing with the occasional silly or annoying questions. That’s rare in this industry, where there’s often a lot of noise and very little transparency.

For my own curiosity, did you learn all of this on your own (Ghidra, IDA and stuff like this ?) or do you have a background or formal studies in automotive electronic engineering ?

I've been doing this for 20 years, MapEV is just a side project. My main income is from www.vehical.net - most serious workshops tuning cars use my tooling for data acquisition.

It is never possible to catch up unless people make their own flashing and datalogging solution that can also write the ASW, then reverse the firmware parts of CP and FoD, as well as the Flexray bus logic.
I would say with the product being so low volume nobody is going to even attempt to do it - does not make financial sense.

What will happen is that for J1.1 (until 06/2023 anyway, after that there's SFD2) there will be places that do these cars for 500 EUR, which will void the warranty. Of course they will not tell the client that, this will be a surprise for much later when the dealer tells the client they can't sell the car for them because 111 point check does not pass anymore.

To anyone reading this - don't mess with the original controller in the car.

Nice work. Going to be installing your product in my 4 PB+ shortly!
