I finally got to drive my 914 again! (IMG:style_emoticons/default/mueba.gif) (IMG:style_emoticons/default/biggrin.gif) Back in June I was having fits with the L-Jet system that was on my car so I decided it was time to tackle a project I was wanting to do for some time, a CIS conversion.
I retrofitted a CIS Basic system to my stock 1.8L engine using parts from various VWs and Mercedes and today I fired it up for the first time and was able to take it for a long drive. It felt AWESOME. Smooth reliable power all the way to redline. It has a nice growl to it too. (IMG:style_emoticons/default/evilgrin.gif) I'm quite impressed. I still have to make some small adjustments but at least now I can get back to driving the car daily and the best part, NO MORE JACKSTANDS! I'm going to drive the snot out of the car this week to get the system dialed in and hopefully next weekend I will take it for a day drive in the mountains. (IMG:style_emoticons/default/driving.gif) More details and pics to come later. The cat is happy too!  |

("K" means "Konstant") There are no injector distributor points. I have to believe it doesn't make any difference how you fire it. |

Some used a fuel pump relay that would not stay on without an ignition signal but that is it. Jim |
