Yes - K-Motronic with R-R tweaks. I had the fuel head rebuilt by Bosch in 2007 and the result is a very smooth motor with idle better than most Spirits. At the same time I also replaced the engine management module and was lucky to get a brand new original one for $400 from the UK - a chap who had bought one and no longer wanted it. I would hate to think what one would have to pay from Crewe Parts today...
