Hello,
Seeing some strange behavior from my Innovate MTX-L wideband when being logged by ECMLink. I have attached two images, one from the end of last year and one from a few days ago, as well as a log from the second image showing the strange readings. The wideband signal used to update quickly and be precise. The signal now shows as a step function, with pre-defined logic levels and a much slower update rate. This wideband 5v signal also runs the narrowband simulation and I believe it's slow rate of update is affecting drivability to an extent. Has anyone seen this before?
A few other facts:
1. I have added an Innovate digital boost gauge and pulled switched 12V from the same ECU pin as the wideband.
2. I did reprogram the gauge to display lambda for my impending switch to flex fuel. It has since been switched back. No change in 5v output behavior.
3. I updated the FW but no change in behavior was seen.
4. I have not changed any wideband switchpoint or narrowband simulation settings in ECMlink between the two images.
5. I have re-calibrated the wideband sensor in free air.
6. The gauge itself updates quickly and smoothly between readings, just as it always did.
Thanks for your help,
Kevin
