I have a Proto 2000 E-7A DCC with sound part number 920-40537. Main problem is the lack of speed and pulling power. With a drag of only 17 cars that are free, wheeling and NMRA specks the fastest I could clock it was 53 sMPH, that was at WOT.
Does the QSI decoder have different settings for speed like Digitrax? Or is it just gear real low?
It had sat for sometime do to uncoupling problems. I was cleaning it up to sell on E-bay when I tried a longer shank coupler and that has solved the problem.
Did they make a powered B unit for this A? I have a powered E-6 2000 B unit that will run circles around the A unit. Is it worth trying to match there, speeds? B unit stock will drag 30 cars at around 70 sMPH.
I started to list it a week ago but just found the pleasure in running it, so it maybe a keeper.
Why do, the Proto E-6’s run so much faster anyway?
I have a Proto E6 with DCC and sound too. I do notice I have to give it a lot of throttle about 1.5 to 2 on my zephyr before it starts to crawl. If I walk up and touch it it will move on lower settings. I love the enigne but i am in the same boat. I have lubricated it and all that so i am not sure either.
GTX my friend. That was the main reson it got placed on the RIP track. I was at a mere 1 amp with the Bachmann E-Z. Now that I have a 8 amp booster I have the needed power. (PM me and we can talk about the booster).
I just don’t like the idea of running WOT unless it is a Mopar and I am racing.
I have a half a dozen Proto 2000 E units, and they all seem to run slow. No idea why, but the QSI sound system seems to suck up a lot of voltage at the start, and I believe the starting voltage to the motor is around six volts, which doesn’t leave much between startup and wide open. Just a guess. There might even be a resistor in the motor circuit, to prevent it from moving at lower voltages, before the sound starts up. Without some sort of resistor in the motor circuit, by the time the sound powered up the loco would be running at half speed.
