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. |

Back on topic...
I think for the "best economy" you should use the 052 ECU with its fuel over run shutoff feature. I have installed one just to see how they run compared to the 044 and it runs nicely and I bet I am getting better MPG. I have data logged with the LM1 and AFR is pretty much the same as with the 044, maybe a hair leaner. I have another 052 to install and test to see if its the same. |
