Question about flywheel stripes

Yes, you can generate a custom tape to match the gear ratio of your locomotive and get 4-chuffs.

Creating a Custom Tach Tape for PS/2 or PS/3

Before worrying about chuff rate place it on layout and set scale speed around 10.  Run a MTH Production engine on same loop at 10 SMPH and see if J is slower or faster.  Do test around 35 and make sure same difference.  If I remember right the Wil Brass J is geared around 40 to 1 which means it will run slower.

So if that is the case you can use the larger fly wheel tape which will put less stripes on the flywheel and trick the processor into thinking the motor is too slow for a set speed and therefor send more voltage to motor to speed it up.  G

Thanks to both of you fella's for the tips. I'll see what I can do.

Most of those Williams and many Weaver will give you that result.   The only Weaver I had good luck with it the New Haven I-5 Hudson.

That post I referenced has a complete collection of tach tape images you can print to get any ratio you need.

I don't have a scale MTH N&W J to compare and measure, so what else could I do?

Trial and error.   Do what George (GGG) suggested.  Run it and determine the percentage of difference between yours and the PS/2 engine you're using to establish a benchmark.  If you are 30% slower, count the stripes on your current flywheel tape and pick one from the files in that post that has 30% fewer stripes and see if that gets you close.

I just wanted to thank you fellows for the help. I finally got it. It took less stripes.
