Funny as usual…

Bosch K-Jetronic injection system, in several guises, was a staple of petrol engines for almost 20 years. Starting from 73, millions of cars from across the spectrum, carried one form or another of Bosch venerable system. A quick, non exhaustive list, will include cars from Porsche, Mercedes, BMW, Audi, VW, Ferrari, Volvo, SAAB, Rolls-Royce… the list goes on.
Millions of those cars survive, and most are quite desirable ones. However, age takes its toll, and several problems are more or less endemic. A high sensitivity to vacuum leaks is one of them, difficult to troubleshoot, but fortunately easy to fix. More worrisome is the dependency on the Warm-Up Regulator (WUR) working perfectly.
The WUR is kind of a simple analog computer. Charged with varying the fuel pressure, and hence the A/F mix, it does so based on engine temperature and time. Later versions, also changed the mix according to admission vacuum. Being purely mechanical it’s reliable, but with enough time everything is finite: springs quit springing, diaphragms get punctured, etc.
A few of the part numbers can be still be found new, most can also be rebuilt by a few specialists, but wouldn’t it be nice if you could bring the WUR into the 21st century ? By giving it an electronic brain, it would allow its characteristics to be altered and fine-tuned, and maybe, some new tricks could be added ?
UT has tried it in the past, but there was some lack of development and they’ve been silent for some time. In the last months, Steve from Reanimotion seems to have taken the flag. An aggressive development schedule with heavy data logging seems to be making a difference to the end result. That, and the clever idea to use the proven MicroSquirt line of ECU’s. That decision freed him from an additional complex sub-project (a special purpose ECU) and enables many possible enhancements for the more crafty people out there.
For those concerned in keeping the period appearance of the engine bay, only needing to replace the WUR is also a plus. Visually, nothing else changes.
Steve will start to take orders shortly.
I never believed the cliché “Germans don’t have a sense of humour”… but for a better proof take a look at this…
Brilliant ! Have you noticed the Porsche tractor on the road to Stuttgart ?
Have you ever been to Autostadt ? Do you know what we’re talking about ?
Autostadt is an automotive “theme park” that sits alongside the VW Wolfsburg plant. Conceived primarily to showcase the many (and expanding… Ducatti) VW group brands, its scope goes beyond that, as it includes a nice museum, temporary exhibitions, offroad tracks, a guided tour to the Wolfsburg plant, (well worth it !) stores, restaurants and many other “goodies”.
I went there for a day in 2000 and enjoyed it immensely. Since then many changes happened, and the “petrolhead” appeal has certainly increased.
You can even pre-order any VW and arrange it to be delivered during your visit. Vehicles ready for Autostadt delivery are stored in two huge glass towers that are a real sight. Recently they can also be “toured” from the inside.
Each VW brand has its own showcase in the form of a specially designed pavillion, meant to reflect (outside and inside) the core values of the particular brand.
Specially important for us, is that the Porsche pavillion was recently completed and opened to the public. It has a striking design, where the roof imitates the shape of a 911 roof. See it !
Warning ! Its not the Porsche Museum… It gives you an overview of Porsche history and its current models, but that’s all. It’s not an alternative to the Porsche Museum in Stuttgart.
There’s also the Lamborghini pavillion…
Bugatti is included in the “Premium Clubhouse” pavillion, along with Bentley…
There’s also the “Zeithaus”, a car museum not confined to just the group brands. It has a permanent exhibition and temporary ones (currently Design Icons).
Finally for your stay, you can keep on the grounds if you check in at the Autostadt Ritz-Carlton, or you can find much cheaper alternatives in nearby Wolfsburg or even Braunschweig.
Now that the holidays are coming, why not take the trip ?
