I'm running into this same thing, except, I'm wondering if I can use the e3d therm on the UM2 mobo? Sounds like it's not possible without some adapter due to the way the electronics are designed.

I believe this is correct. It would be simpler to just use a PT100 sensor. You should be able to use the one that came with the UM unless you damaged it. The Ultimainboard's thermal sensor input is special amplifier circuitry designed just for PT100 type sensors.
Edited by JRDMThanks for clarifying JDRM,
I just didn't realize the cartridge was the same size and shape since my old one failed and needed to be replaced anyway. I got a new PT100 and the E3D is working great now. It's nice to see somewhat of a standard in those shapes.
Hi, I approached the problem differently and made another one that looks like the olson block only of aluminum.

Hi Alexwimjan,
That hot-end design looks great but why did you design a new kind of heaterblock for the E3D v6 if I may ask?
Hallo,Because with this lookalike olson block you can use the original UM2 heating element and the temp.sensor. Also the connecting wires are on the back. It works very well, I packed it with glass wool (insulation paper). I will take a picture soon.
I have improved the attachment of the E3D by sliding a rip between it so that it can no longer turn around.

Update:
I think I found the solution, I misread in the E3D guide that they use a PT100 temperature sensor instead of the standard 100k thermistor. It makes sense that the Temp1 input on the Ultimaker electronics board cannot handle a 100k thermistor out of the box because the electronics on the board are tuned towards the PT100 setup (which works on a different principle). So I took the original Ultimaker PT100 from the hot end and mounted it in the E3D V6, changed the temperature sensor parameter in the firmware back to option "20" which is the default setting and now the temperature readings are correct and the hotend heats up as quickly as the original. Time for a first test print :-)
