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. |

For what it is worth. Here are the measured resistances and temps for sensor 0 280 130 017
32 degress = 3455 ohms 66 degress = 1627 ohms 212 degrees = 120 ohms. Unfortunately this is not a linear curve. The points on the curve can be calculated by using the Steinhart-Hart equation. The math is too much work for me but if someone wants the values these represent I'll post them. Or I'll wait for one of the kids to wakeup and solve it on their graphing calculators. Dave |
