A Class CV Reprogramming.

[Fowler4f]

As I don’t wish to purchase an ESU Decoder Programmer unit for a one off.
I would like to run an A Class loco at max speed of 25 mph for hauling unfitted goods trains.

So far I have set, the max speed on my ECos @25mph, and altered the following, CV3 Value 200, CV4 Value 200, CV5 Value 85 & CV6 Value 45. I’m not sure how accurate these are to achieve my aim.

Does anyone know, is there a table published for altering speeds/CV’s or has a Guru on here done something similar ?

Any help appreciated.

Thanks

Good question.

Apologies for delay in replying. These are my thoughts at the moment.

25 mph at scale ratio 1:76 can be observed as a speed of 14.66 cm per second, or 0.1466 metres per second, or 5.77 inches per second.

5.77 inches per second can also be expressed as a speed of 12 inches (distance) in 2.08 seconds (time).

So these would be the actual observable speeds at model scale 1:76 for a "scale speed" of 25mph.

25 mph converts to 40.23 kmh

While the Ecos allows the user to to define a range of speed from 0 to a max value (kmh), the speedometer feature may not represent the actual speed of the model.

I would like to experiment with this myself to evalaute what the Ecos can do.

Your question is a good starting point.

I look forward to seeing the results, thanks again.
