Lambda 4.9 heating issues

EMU BLACK / CLASSIC
1

i got my ecumaster black installed a couple or weeks ago but i running in to a issue.

so my lambda is very inconsistent heating up . so it wont heat up at the first start not at the second or even third but if the car is warm and and i start the car and hold the rpm a bit high for the heat up time it often works and it wont stop working but to get it working it always a nightmare.

i read that user (Philip) add a resistor between 5v and wbo vs. i never read that i need to do that or is my problem unrelated??

thank you all is advanced

Connect the ECU to your PC, load the software and check the hardware revision. If its revision O or earlier you need to add the resistor.

I just checked i got revision r so it shouldn’t apply.

Im gonna buy a new sensor and put it further downstream maybe it broke overheated or something it that regard
