m40i - engine logging - help needed
Hi,
I'm considering upgrading the exhaust with a downpipe in my M40i soon, and I'd like to log some data on the car in its current factory state, then compare it to the new setup. I'm generally interested in EGT, lambda readings, and the exhaust pressure/differential sensor. I'm in the EU, so we're talking about the version with OPF and a downpipe with 3 sensors. I purchased vLinker and BimmerLink. I managed to find readings from the first lambda (before the catalytic converter) and the overall exhaust gas temperature (assuming it's also a reading from the first lambda). However, I can't find readings from the second lambda sensor (after the catalytic converter) and from the exhaust pressure/differential sensor. Can someone please suggest what I should look for? Alternatively, which other software should I use that provides these readings and allows me to log them in real-time? Thank you, Daniel |
