EV remapping & tuning
Discussion
I though the independent remapping and tuning industry would be in the same decline as petrol and diesel over the next few years so was surprised to see a promotional email about remapping Porsche/Audi. I wonder how these remaps survive an OTA software update from the manufacturer?.

Yes and I hope they warranty the battery as 40-50k for a new one is no joke. The extra thermal stress must be a key consideration.
its a gamble for sure, on the Taycan models, how much is actual physical hardware changes and how much is deliberate software restriction on lower models Jayemm's just done a video on this with MRC's demonstrator Taycan Turbo, they say there's no hardware changes between the Turbo and Turbo S as an example - however there were a few people in the comments quick to point out there's various heat management system differences.
I like the idea and would be good for the enthusiast if it were less risky, but I cant imagine many people will be comfortable risking a 50k repair bill for a bit of extra power.
I did see a post elsewhere a few months back about people having this done where they supplied an extra control unit for the motors which then has the revised software applied, meaning they can switch out back to their original if they had issues. The fact most manufacturers can now tell if a car has previously been mapped would mean I wouldn't be confident doing this either, as they'd definitely be able to tell you'd been running a different control unit.

Two thoughts:
- The Fisker Ocean community: I have a vague memory of reading about it is getting the cars closer to the open hardware/open source model. Couldn't find the details/article, though.
- Another vague memory of an article (remembered: it was the French L'Argus magazine) about the Kia EV6 GT on Nurburgring that mentioned a gradual drop in performance on the second lap (but said it was preferable to early Taycans, where the performance dropped more abruptly: https://www.largus.fr/actualite-automobile/essai-e...
This give some insights into the Porsche battery and the complex cooling system.

Is that any worse than you'd pay for a brand new engine on something like a Porsche or higher-end Audi. Modifying cars for more power has always been a potentially expensive gamble.
People have been tuning 'new' expensive cars that void the warranty for years I am not surprised people are doing it with battery powered cars. I personally see less of a market for it as electric cars are generally pretty quick to start with. But unlocking disabled features on lower spec cars sounds more helpful.

The issue with unlocking features is that with over the air updates and data back to manufacturers now, they will know it's been messed with. Voiding warranty... Difference with tuning newer ICE cars is if the engine lunches itself it can more than likely be rebuilt for substantially less than a 'new' engine from the manufacturer, or even swap in a replacement from a crashed car. Plenty of specialists would do that, however if your Taycan motor fails you're most likely going to need to take it to Porsche and pay whatever magic figure they present you with. Until we start seeing specialists who can do cost-effective motor/battery repairs then the potential cost if it goes wrong is much higher with EVs.
