They don't do anything to the KE jetronic box. Remember even the KE, jetronic boks is interchangeable in between the 260 and 300 model. No difrence there, either. Remember it's the drawing In of air that controls, directly the mixture. So when the 3.4 draws in more, air due to its larger stroke and bore. It's, automatically opening more for the fuel. That mixture won't change due to larger, engine capacity. It's acle on a Standart engine to give more than 35% on top of the, Standart needs remember the, same system is used for the w126 560 engine. Same injectors as M104. 980. Only thing AMG modified were the ignition full throttle advancing all other electrics stayes the same. That the fantastic life with Jetronic. You can tune an engine without having to mess, around for hours on end on fuel mapping ignition etc. Sendt fra min SM-S918B med Tapatalk |

You need a microsquirt ecu, the frankencis unit, a O2 wideband sensor, a map sensor, rpm signal,air and water temperature for to start. (I'm talking about the KE Jetronic version.) If you want you can control also the ignition timing with megasquirt, for to do this you have to install a trigger wheel on the crankshaft pulley. If you want a fuel pressure sensor, a throttle position sensor are also options. The fuel system remain the original one with its injectors, distributor etc, as the ignition system, coil,cables etc. Using "tuner studio" installed on your portable pc to interface with microsquirt you have the complete control over fuel system and Ignition timing, if you want. Tunerstudio is the software used for the settings and to tune your car on the street or on a dyno. The Frankencis unit itself is a little black box that is electrically connected between microsquirt and the EHA valve. To know more there is a section on this platform with all the questions answered: Digital WUR plus? ( FrankenCIS ) - Pelican Parts Forums

The link in PP is 73 pages; since you are thoroughly familiar with the thread, would you please direct us to the pertinent page(s) that describe the FrankenCIS-KE? Or as alternative, post copies of the instructions that were supplied by FrankenCIS for your KE installation. The connections of that "little black box" and some insight into its functions are of specific interest. |

Here You can see the Frankencis module and the connections of microsquirt-Frankencis- EHA. You can download this for the installation instructions: http://www.frankencis.com/portals/FrankenCIS/FrankenCISTechnical.pdf

Thank you -
As expected, an interface to separate the positive & negative signals that drive the EHA. |
