Mate I have learnt show much from your videos and knowledge in electrical, Ive been watching your vids for 10 yrs now, and you are the first to show how BEMF works as its hard to find on the utube, thanks again Greg
Thanks very much Mark! Have I really been ranting on for a decade..LOL . I appreciate the continued support and I'm glad you find the videos helpful. Part 3 on the way soon. Take care and cheers, Gregg.
Thanks Deryk! Most of the CVs are the same in ESU, you'll just have to double check before you start changing them.Glad you enjoy the videos and I appreciate the comments. Cheers Gregg.
Thanks Brownie! There is a lot to learn with DCC, but taking small steps at a time makes it a lot easier. There may be a rant on the next one...... Cheers Gregg.
Greg's School of CV's love it! Unfortunately we're renovating our basement and can't work on the hobby. Looking forward to using the lesson when the project's completed. Another great lesson Greg Thank You.
Hi Greg from Kiwi land. Another great vid mate. You explained BEF better than my old trade tutors way back in the early seventies. I have (x1) T2 decoder, now looking forward to having a good tweek with the CV's. I hope sometime in the future you will also have time do a series on CV tweeking of T1 decoders. Be safe & healthy mate.
Hi Salty, thanks for watching and I'm glad you enjoy the videos! All the CV's are the same for TSU1 decoders , but the value of 212 will be about half in the T1 compared to T2! SO no excuse not to play with your T1's as well..LOL. Just try different values until you're happy with the result! Keep well and thanks for watching! Gregg.
Thanks Peter! Some of the CV's will be different on ESU I think? Just make sure you double check before you start changing values! Glad you got some good results, but keep it quiet or you'll upset the ESU fanboys..LOL Cheers Gregg,
@@FishplateFilms Some people get very brand fanatical. I don't care as long as it works. I'm not hitched to ESU, it's just what most Australian brands come with. Your tips last week were great and I'm sure (after checking the ESU / tsunami corresponding addresses) it'll work a treat.
Thanks for explaining the bemf in detail Gregg. This is valuable stuff. I'm headed to the club layout early tomorrow to make some changes. Hey Greg.... WORM DRIVES !!...... :)
Great video, I watched it three times, hopefully I can start experimenting soon. I am surprised that decoders don’t talk to each other if they can measure the voltage used. That would eliminate speed matching. Great video, to bad I was sleeping in Physics in high school. Maybe I could have came out with the smart decoder. Cheers from mild Nebraska. Terry. Can’t wait for video three Gregg.
HI Terry , glad you're enjoying the videos and look forward to your results! BEMF still isn't a "speed" sensor, it can keep a motor at a "speed" but it's not a RPM measure as it relies on current. If we had better drives ........you know where I'm going..LOL. Even if decoders could talk to each other, you would need a lot more smarts to enable that to happen! The best method is to reduce the BEMF to zero as soon as possible. Part 3 in a bout a week...I'm fighting a cold at the moment and have no voice. Cheers Gregg.
This is great, just what I needed. I have an Athearn MP15AC with Tsunami that won’t start with a load until it reaches speed step 10-15 out of 28 and then leaps away. It will run at low speed once already moving though. Going to try adjusting these CVs to see if that sorts it or if it’s something else.
Hi Mark, don't forget to adjust your start voltage CV2 before you adjust the BEMF . Watch part 1 of this series to adjust your speed table and start volts . Also you should use 128 speed steps instead of 28, you will get a smoother control :-). Thanks for watching. Cheers Gregg.
Thanks very much Colin! Look out for many more CV tips coming up! I got the shirt from a model train shop in Tehachapi! It's closed now but I'm sure you can get shirts like this online? Cheers Gregg.
I haven't owned a tsunami two decoder yet, so I should buy one and see for myself if it is better than the first generation tsunami decoders or loksound five decoders;-) Cheers, Joe;-)
Thanks Dennis! I've always said that Tsunamis are a "operators" decoder, and that you can fine tune them to your own style. Glad you find the videos helpful. Cheers Gregg.
Hey Greg, I have Tsunami 2 decoders as well. George said that those cv's didn't need to be adjusted. Only cv 215, set this to match track voltage. I read the function of these cv's and it didn't make alot of sense. Do these cv's have a default value in them from Soundtraxx? Thank you for the explanation, it makes more sense now. Chuck
Thank you for this, but I'm thick headed and still a little confused. Were you holding the loco from moving while adjusting each CV? Also, was there a specific speed step you were wanting to allow the wheel slip to begin?
You're welcome! Yes I was holding the loco for most of the adjustments, especially 212! Just have a play and see what works best for you...and don't forget to write down your values as you go! Gregg :-)
@@FishplateFilms Thanks, is there a goal speed step to allow wheel slip? like less than 10 but more than 5? do you have momentum turned off for the adjustments?
@@OtterCreek Totally up to you , but before 10 ( with 128 speed steps) is a good choice! Having momentum on will give you a better idea of how the loco will perform on track with a train. Gregg .
Hi Norman, yes the value in TSU1 is usually about 85 -100 on my T1's. All my T2's need at least 200 in CV 212 , but they are a much less aggressive BEMF and beautiful to run! Thanks for watching Sir. CHeers Gregg.
@@FishplateFilms Just for your info, I have some OMI brass that get as low as 60 in CV212 before they stop spinning in speed step 1. Thanks for explaining BEMF.
@@normancnclearwatersub7505 There you go! CV 209 boosts it a little and I use that to "soften" starts with a heavy load. I use more 209 on the TSU2's and leave 212 at 220 . My Atlas units are set to about 75-80 for 212 , but 60 is a good indicator of motor quality! Gregg :-)
Hi Jason, it does depending on the loc and what you have set in 209, 2, and 210, but as a rule , I usually try for some slip at speed step 10 -15, using 128 steps of course! another one is to put a decent cut of cars on the loco and see how it pulls away. I find the Tsunami 2's need a lot more of 212, but they will pull a lot smoother under load at a lower setting of 212. Hope this helps. Cheers Gregg.
No John , we covered that in Part 1, with CV 2. This is to adjust the motor torque on start , after you have set the start volts. Go back and watch part 1 :-) Cheers Gregg.
@@FishplateFilms Gregg,i never explained properly, I meant under load,ie. The loco moves fine by itself,but then you put 12 wagons on and it won't move ,increasing cv212 should help the loco pull the wagons? I think that's right. Cheers John.
Hi Tommy, I would leave 210 at the factory default of about 25. CV209 will depend on how you set 212 and your start voltage CV2. I have most of my locos at about 100 for CV209. Gregg .:-)

Impressive. With a little tweaking, you can make a tsunami decoder control a locomotive as smoothly as a loksound decoder can.
The Tsunami 2 has motor control equal or better than ESU in my opinion:-)
Gregg :-)
I haven't owned a tsunami two decoder yet, so I should buy one and see for myself if it is better than the first generation tsunami decoders or loksound five decoders;-) Cheers, Joe;-)
