Here are my thoughts on a systematic approach to optimizing D-Jetronic for a specific stock or near-stock engine - just putting this down and looking for comments:
Comments? If the intake system has been significantly modified (e.g. different cam, big valves, etc.), then to do the dyno procedure correctly, an assessment of the VE changes would need to be made, and the ECU daughter-card SC circuit would need mods - but this is beyond a reasonable approach for most people. |

So, from what I see there, if I want the motor to be a tad richer over the entire heat range, I have to start at 500 ohms.
Anything less seems to only affect the warm up time period, which may only last a few minutes. Now, back to the MPS. What is a simple and effective way to set up the MPS on a bench, like it was done at the factory, BUT...big BUT...with normal tools, normal guages...I will consider normal a hand vacuum pump. I would love to find a way to do this without buying the two (one time use) tools to set up the car. Without an O2 sensor, and without the special meter (cant remember the name) These two tools seem to be one time use only..once the car is set, its set...no need to futz with it iny more, at least the FI settings..they are not dynamic, so no need to watch them with a meter/guage...who cares.
