Golf 6 Throttle Control with RPM/Speed Signal

Hello everyone,

Looking for a simple way to extract the speed and RPM signal from the CAN bus. The whole idea is that I want to install a valve in the exhaust/muffler to control the engine's RPM and speed, so that it complies with the European Economic Community (EEC) regulations and makes the entire project TÜV (German technical inspection authority) compliant.

Currently, all the hardware is still open; only the valve at the end of the chain needs to be switched to the closed position when certain conditions are met.

I've read that there's a CAN shield available for the Arduino, and a microcontroller would probably also be suitable (although I haven't worked with those before, I'm more familiar with Arduino). I've also heard of a Raspberry Pi solution, but I personally think that's overkill.

I would be very grateful for any suggestions or assistance.

Regards,
Tim.

Since both speed and engine RPM can be retrieved via diagnostics, it is actually possible to control the flap using an Arduino, a CAN shield, and a relay card.

In that case, it would be feasible. However, you wouldn't need to go to TÜV (German technical inspection authority) with it, because neither the Arduino nor the control system itself would receive an ABE (General Operating Permit), and therefore would not be eligible for TÜV approval. Even a single unit inspection would require the hardware to have a type approval certificate.

But as a "DIY project," it's not that difficult for a beginner, and I think it's a good way to get started exploring the world of microcontrollers.

Tim,

I was recently approached about developing something similar. How is your valve controlled or actuated?
