I just got this engine in today (finally) from Ebay and am having a speed control issue with it. When running ( with/without cars and with/without smoke, makes no difference) it runs erratically, speeds up, slows down, jerks everything but run smooth. Also mind you this is at 3 mph on the DCS remote. I have no ideas on what to do. Reloading the sound set and a feature reset made no difference either. I was able to run it half a lap on my layout before it started acting funny. Attached is a video of it with cars and smoke. I will take another one later that has no cars or smoke. This engine had the white battery which I replaced with an EBL before even putting power to it. It had 5 1/2 hours on it before I ran it today. Any ideas please let me know. I'm thinking it has something to do with the tach or speed sensor but I could be wrong. Is this something that is fixable with the 5v board in it or does it need a PS/32 board? Using an MRC pure power dual for power.

I haven't opened the engine up. I have a local tech who I will have take a look at it. Is the tach board a fixable part without needing the PS32 Board. I rather not pay for that if I don't need it right now.
That doesn't look like a board problem. Maybe something mechanical
I'd suspect either the tach sensor and wiring or as Dave says, a mechanical drive train issue.
I'll open the engine tonight and see what I find. I'll snap some pics too.
Well. I definitely know why it's not running right. Part of the tach tape is missing and the tape that is there is nasty! Can I get another one? If so where?

Fixed! Printed a new tach tape. Runs like it should now.
Told you it was the tach sensor.

Well it wasn't Actually Alan called asking about the tape. Pretty dirty old style paper tape. G

Splitting hairs here aren't we? The tach sensor couldn't read the tape.
