Disclaimer:
I am not an expert, just someone that loves figure out how Porsche’s work. First is was MFI where I eliminated the thermostat, adding an external AFR adjustment knob to the injection pump, remote cold start priming, and grinding on my own space cam for my 2.8 twin plug build. Next it was CIS when about 7 years ago I set up my own WUR add on that was programmable for all loads and rpm levels so I achieved near ideal AFR’s everywhere, more fuel up top, and increased throttle response. Way before the D-WUR popped up. My thoughts also resulted in the first higher flow fuel head that went to Brent 930 that then became the HF head. I also first suggested the use of the RPM boost circuit clamp using an MSD switch that was just one way to try to tame the increased fuel that came with the modified fuel head and a desire to access increase fuel needed up top by lowering control pressure (a reverse Andial-Fueler approach).
I make a lot of mistakes along the way to learning and might have made some here.
However I hope other’s will offer positive correction where needed and new ideas so we can all benefit.
