i have seen a CIS on a 914-4. my fuzzy thinking seems to pull up the name "Ed Morrow" whom i think did a CIS turbo -4. could be wrong but perhaps a start of a search.

I seen CIS on type 4 but not CIS-E. CIS-E has a knock sensor and timing is control by the ECU. |

didn't catch the significance of the "-E". i thought air cooled motors couldn't use knock sensors since they are so noisy.

That was Ed Viella that put CIS on a turbo'd 914 engine.

I used CIS-E on my turbo but there is no knock sensor or timing control built in. What car did you take the FI from?

I got the CIS-E from a 1990 Audi 80 with a 3A Gas engine. It has a O2 sensor, knock sensor. It also has electronic timing control by the knock sensor. Thats why I'm using it with a turbo. Bosch number 0-261-200-220/221 know as KE-Motronic |

With this system there is no adjustments to made, its automatic, the only thing
that has to be added is the fuel enrichment circuit for wide open throttle to run it rich. |

The CIS-E systems are pretty particular about the engine they are attached too. The system has been designed around the airflow and ignition requirements of the particular engine. You might try and find the CIS lambda model that was installed on VW's and AUDI's before the CIS-E. You can simulate the O2 sensor signal to adjust the A/F ratio for the engine. If I remember correctly you can also have the WOT enrichment too. I did a lot of research last year on STF and other forums. There is a huge amount of information out there that is easy to find. I was going to install CIS on my VW bus but work has kept me too busy to finish the project.

One thing to watch out for on the -e, they run quite a bit leaner than CIS. The system utilizes the knock sensor in combination w/ the O2 to lean the system out to improve mileage. At least it's the case w/ Ke-Jetronic, I would be surprised if Ke-Motronic was much different.

KE-Motronic CIS-E III works differently it will hold the A/F at 14.7 till WOT, then
a addedrichment circuit using the cold start valve changes it to 12 to 1 just right for a turbo engine. Thats why I went with this system. |

Corrected some wiring problems and air leaks. Engine runs great now. It time
to start to make the headers for the K02 turbo and get it running. |
