I just got informed today that my local tuning shop has started to take in Taycans and E-Tron GTs where they can modify the software to unlock hundreds more horses for some models.

There also seem to be other shops providing the same service, like Unlimited Tuning. So it seems legit.

Does anything like this exist for any BMW i-model yet? In particular interested in anything that can make my i3 94Ah go faster.

I thought the i3 maximum speed is set by the gear and maximum electric motor rpm…

There are certainly hardware limitations to take into account, but manipulating the control parameters of the drivetrain – extracting a bit more from the inverter management and power delivery – should be possible without completely crossing the built-in safety buffer. Especially if we’re not talking about the extremes (from a standstill or at top speed), but rather focusing on making the car more responsive in the mid-range.

That’s more or less how all tuners work with chips for ICE cars as well. They eat slightly into the large safety margins that manufacturers have set, at the expense of increased long-term wear.

In the case of tuning a Porsche Taycan or Audi E-tron GT, it seems to be the same philosophy applied by the companies offering these upgrades. In the end, it’s up to each owner to decide whether it’s worth it or not – but among those interested in more performance, I’d assume there’s usually a higher risk appetite and a higher tolerance for potential failures. Personally, I wouldn’t mind having to replace a motor every now and then if it meant getting significantly more performance in return. But I completely understand that many others would see that as a very bad trade-off.

Anyway, if anyone has seen any sort of ECU hack for BMW i - please put a post here.
