96RAF Posted January 20, 2017 Share Posted January 20, 2017 Dazzler.........I noticed a new thread today in HornbyDCC re TTS decoder CV150-154 to which Chrissaf responded with a link to Tony's Trains which you may find useful to read, particularly this para..........QSI IndustriesThe new release level 7 (also the upgrade) of the QSI decoders has a very sophisticated four level speed control using Back-Emf and PID. Information on setting up the PID CVs is in the DCC Reference Manual version 4.0. Version 7 is the new upgraded chip available from QSI Solutions. A new page manual can be downloaded from QSI Solutions web site. The setup information can be found starting on page 170 to page 175. There are some good hints on tuning PID parameters. The CV values in these (upgrade) chips have been established by running a number of sample locomotives. As locomotive wear and due to manufacturing differences, some locomotive performance may be improved by re-tuning the CV values. Daz already said CV7 reads value 7 so he is at the latest revision it would appear. I can't agree with QSI reported comments later in this thread that the Elite is at fault. Not only is it designed and built to NMRA reqs but it has been tested by them and issued with a compliancy warrant. That doesnt happen unless it passes all their test. Sounds to me like QSI making excuses for their oddly complex decoder.Rob Link to comment Share on other sites More sharing options...
Dazzler down under Posted January 23, 2017 Author Share Posted January 23, 2017 Well I can bring this thread to a close, there has been no fix. After contacting Eureka models, QSI solutions and Hornby they all wanna blame each other. Funny how the loco works on 2 other DCC systems and won't work with the elite. I've given up trying to run this loco it's just too frustrating I'll box it back up and sell it I think. Link to comment Share on other sites More sharing options...
Dazzler down under Posted February 7, 2017 Author Share Posted February 7, 2017 Just for the record, ive been in contact with a guy who uses the elite and runs locos with QSI decoders without issue so now im really stumped. considered selling the decoder but you need to be an auto electrician to get the thing out.

Fireman_Ian Posted February 8, 2017 Share Posted February 8, 2017 Hi Dazzler. I had the same problem with an Atlas loco with a QSI sound decoder with the elite. I had to change cv11 to a higher value then it has been working great. Ian. Link to comment Share on other sites More sharing options...
Fireman_Ian Posted February 8, 2017 Share Posted February 8, 2017 CV11 has something to do with the packet timeout value with the default =0, apparently QSI decoders require a higher timeout to work with the Elite. Link to comment Share on other sites More sharing options...
RB51 Posted February 8, 2017 Share Posted February 8, 2017 Thanks, Fireman Ian. Are you able to give a suggestion as to a sensible value to start with or what the available range might be? It is appreciated that Dazzler will have a certain amount of trial and error to go through, but if this works that will be fantastic - and a great testament to the power of the forum.

Fireman_Ian Posted February 8, 2017 Share Posted February 8, 2017 I think the values are 0 to 20 my Atlas US Diesel works with a value of 5 so that may be a good place to start. Link to comment Share on other sites More sharing options...

Dazzler down under Posted February 9, 2017 Author Share Posted February 9, 2017 That's very helpful Ian, thanks very much, my loco is currently at a mates house being tested on another system and by all reports seems to be running perfectly. I will see him in a few weeks and retrieve the loco, when I get it back I will implement your suggestion and let everyone know how I get on.

Dazzler down under Posted February 9, 2017 Author Share Posted February 9, 2017 Should Ian's suggestion solve my problem I think the mods should change the title of this thread to Using a QSI decoder with the elite so it's easier for others to find in the search once this thread gets lost because if this suggestion works it's a handy piece of information indeed and may save other QSI users many months of angst if they manage to find this thread.

Dazzler down under Posted February 11, 2017 Author Share Posted February 11, 2017 Ok, just got a call from my mate, he has both the powercab and the elite. On the PC the loco worked fine, on his elite he had the same problems I've had, so he reset the decoder using the PC and it now runs perfect with the elite. Something so simple, I couldn't reset the decoder on my elite due to corruption issues and RM didn't recognise the decoder so I couldn't do it there either but by all accounts my mate got it working with a simple reset.

choralc Posted February 12, 2017 Share Posted February 12, 2017 Brilliant to hear DDU. Quite a significant investment in a well sought after model. Being ex-NSW if I had decided on Aussie HO for my hobby that would have been a model I would have definitely wanted, Link to comment Share on other sites More sharing options...
Dazzler down under Posted February 12, 2017 Author Share Posted February 12, 2017 its a lovely model choralc, although I model British outline I still had to have me a 3801. I figure if I wanted I can run it next to my flying Scotsman and relive the moment that sparked my love for steam engines as a kid when the Scotsman came here for a visit for our bicentenary and was double headed with 3801. Ah the memories. Link to comment Share on other sites More sharing options...
Dazzler down under Posted February 13, 2017 Author Share Posted February 13, 2017 Ive actually had the model a number of years but only run it on dc a few times, it's not even run in yet but while my mate has it he will run it in for me I should have it back home in a week or 2 he lives miles away.

Dazzler down under Posted April 7, 2017 Author Share Posted April 7, 2017 As promised, a few action pics of the 3801 finally running on the Hornby elite, also have a vid but can't post it on the forum/media/tinymce_upload/587b19d6f6b22f78ba841ca584fa6adf.JPG/media/tinymce_upload/705753499f0819c16bb5489346f08e1a.JPG Link to comment Share on other sites More sharing options...
