Lambda - practical (1)

After some theory about lambda, there was this very sunny early March day (yesterday) and the urge to take that car for a long drive out. Although the settings have not been finished yet, I just had to drive! The car works fine and the injection system gives the engine more grunt and drivability. Unfortunately, the consumption is very high (around 14 liter/km). Time to connect that lambda sensor!

Since older cars didn't have a lambda sensor, I had to add a bung somewhere in the exhaust system to screw the sensor in. When there is no lambda sensor, the hole can be closed with an appropriate screw.

Routing of cables always is an issue in a small car, but after some fiddling, I managed to place that big connector near the fusebox and made the cable disappear under the dashboard. A quick check with the provisionally connected gauge showed that the engine is running quite rich (around lambda 11). This explains the high fuel consumption. Next: connect the lambda sensor controller to the ECU.
Cheers.
