Good news for you guys who want to tuned the new Twizy models Which are produced after July 2016
I've finally just last week managed to tune the new Twizy models that are manufactured after July 2016 :-))))))))))))))))
I have managed to switch firmware on the motor controller and together with a Powerbox this now works perfectly. I only have left some minor details about how we will do this in practice. It's not 100% sure yet that a Powerbox can handle this all by itself and maybe need some help from an IXXAT interface to do the actual firmware update. we'll see what I can achieve
Powerbox's task here is to handle the DNR buttons (without the Powerbox, you will not be able to use the original DNR buttons) Powerbosen will also simulate various CAN messages to make the dashboard work, this are not possible on the official firmware. Beside this, the Powerbox will have all the common features that are on a regular Powerwerbox V2
The firmware update on the motor controller can not be reversed, so this may not be applicable to those who want to keep the warranty on the car. Your Twizy can be returned to the original power map but Renault will maybe be able to detect this if thay are going to diagnosing your controller since it does not have the original firmware anymore. The firmware we use is Sevcon's official firmware so this is not dangerous for your controller.
This feature is also meant to be used on used Renault motor controllers.
As is the case today, Renault locks your motor controller to your specific car. That means, you can not buy a used controller and mount it in a different car. You are currently forced to buy a new motor controller from Renault. Not even Renault service center can configure a used controller to work in another car. I'm pretty sure this is a breach of various laws and this put an end to all sales of used motor controllers. Renault should perhaps have been sued for this.
With this firmware update, you can now also use a used controller if you want and can then put aside your original controller until you need it due to warranty issues
or if you're only in a situation where you need a new motor controller and would rather buy it used. You can now do that
