UL ECU Update and Issues

 Up until now, all of my interactions with UL Power have been excellent.  Super responsive (considering time zones), and reasonable.

UL changed a number of ECU parameters last year, and mine had to go back to the factory in Belgium for a software update.  So I packed it up in March, and UL arranged for everything else.

In May, I reinstalled the ECU.  Everything appeared fine... but the CANBUS feed from the ECU was now on lane B and not lane A.  I also thought there were a bunch of sensor failures (but that turned out to NOT be the case).

UL claimed that the CANBUS lane A / B decision is made via the cable.  After some sleuthing on the diagrams I found the pins and checked - no jumper.  UL then stated they were going to test with my version of hardware - and they found the issue.

The explanation given:  I have board version 63, and they are now on 64.  They added additional input ports, which shifted the CANBUS lane A / B jumper.  

The label on the ECU says

HW ver 1-63

SW ver 07-022

Based on my experience in over 30 years of dealing with hardware and software issues, there are more issues than what I am being told.  They GUARANTEE everything is fine, and no need to update the ECU software.

I do not agree.

I am trying to stay positive on UL as 1 bad experience should not taint all of the good things they do and have done.  But this has definitely left a bad taste with me.
