Hi, car is running great with stock calibration and 3.2.x software.

i have installed the lambda sensor but i don't have the 55 pin ecu, only 25 pin. Is there a way to use it? the 25 pin ecu misses the heater for the lambda.

Now, i don't know if the 55 pin ecu is located in another place in my car so it's just matter of finding it or it's actually possible that it isn't equipped with it ('91 190e M102 1.8L) but my friend has the 2.0L version and he has both 25pin and 55pin in the battery compartment.

Any ideas? Thanks

You can connect heater to the fuel pump supply, and it will turn on with the engine, as intended.
Don't forget to install a fuse.
