Need tech details for decoder in N-scale GE 44-ton switcher

Bachmann Spectrum Item# 81853 - "N" GE 44 TON DIESEL SWITCHER

As I do on all my locos, I'm trying to limit the top speed.

This loco seems to have no capability for such control. It seems there is either no CV05, or it takes values I'm not familiar with. Also, there seems to be no Speed Table - is that correct?

Also, I need to know things such as: what is the reset CV, and what value does it take?

Where can I get tech details about the identity and capabilities of this decoder?

I appreciate your help!

The Bachmann decoders do not have bemf, and do not support CV 05 or have any speed tables, but you can replace it with a more advanced decoder with bemf capabilities. It is essentially a Lenz decoder with basic capabilities.
CV 1 is address
CV 2 is start voltage
CV 3 is acceleration
CV 4 is deceleration
CVs17-19 are addresses
CV 29 is addresses, digital/analog, speed steps, and direction
CV 50 is brake momentum
CV 51 is F1-F8 dimming
CV 52 is brightness

I haven't seen any replacement decoders yet - do you know of any?

Try a digitrax N or Z scale decoder. Bachmann only makes basic decoders, so would would have to replace it with a different brand.

I'm now researching which Z-scale decoder to try... Probably won't do any conversion till summer, but I'll post when I've got something working...
