I sent my Cascadia DD15 ECU to The ECU Pro after the truck had problems with the cruise control and the dealer quoted me a crazy price. They diagnosed and repair it over the weekend ( send it in Thursday afternoon, by Tuesday I had it back). Plugged it in and the truck fired right up, no issues at all. Great communication and way cheaper than replacing the whole unit. Definitely recommand The ECU Pro if you've got ECU problems on your Freightliner.

I sent in my ECU with instructions to repair or replace if necesarry. They tested within a day of receiving it and found no problems. They took a video of my ECU in their BMW which showed the car starting and running. I appreciate that they didn't "find" problems that weren't there. I got updates from them at each milestone. I also ordered a duplicate key which is genuine BMW. Just under 2 weeks from shipping it out to receiving it back. These guys are among the best specialty repair shops I've dealt with. I highly recommend!

Found their label on a ECU in a car I bought. Figured I would give them a try and very glad I did. Could have charged me $500 for what I thought was already a bad ECU. Instead told me the problem was elsewhere.
