I just picked up a TAS EOB set up for steam. Does anyone know what the tach stripe count is meant to be for these engines? Also was the r2lc standard Lionel or a specific use one from TAS. It has 08Z on the chip. Also the sound sets, it is Lionel boards but was curious if they were TAS specific sound sets or Lionel provided. Thanks G

The TAS stuff uses standard Lionel R2LC-C08 boards and standard RS4 boards as well. I've swapped in a number of all the Lionel boards into the EOB sets with no issues.
There are tach strips for various brands included in the attached file, the exact stripe count is not that critical. I suspect it might be like the MTH strips in that there's a maximum density for a specific flywheel speed, but I've never encountered an issue. I have a few EOB equipped locomotives and I've worked on a number of others.
The tach strips in the kits were designed to install on the flywheel with the best spacing where the strip ends met at 360 degrees. A uniform black/white all the way around.
Setting the Chuff Rate for Steam Locomotives. From an EOB install instruction booklet. This is after setting Pre Pulse and Backround Pulse.
Master Chuff Reset code This code is used to generate the chuff input that triggers the sound system. EOB allows you to select between 1, 2, and 4 chuffs per revolution while the locomotive is moving, or stopped, this is done by using simple math. The master Chuff reset code is the number of stripes the sensor counts before it triggers the sound system to chuff. This rest code is the number of stripes counted in one complete revolution of the drivers. When you select (two) or (four) chuffs per revolution, the processor on the EOB board divides the Master chuff reset code by either two or four to produce the proper chuff triggers. For example, if the Master chuff reset code is 200, the sensor will count 200 stripes and then produce a trigger for the sound system at one chuff per revolution. When in 2 chuffs per revolution the sensor will count 100 stripes before it produces a chuff trigger. For (4) chuffs per revolution it counts 50 stripes.
The Master chuff Reset code is determined by trial and error. 
With the Cab1:
ENG+##+DIR+AUX1+AUX1+AUX1+6+### (### is a 3 digit code) ( The horn will sound after the 3rd AUX1, a coupler sound after 6, a coupler sound after the 1st and 2nd digits of the 3 digit code, and a horn after the 3rd digit. Noted that 350 is a good start code.
By accessing this feature the locomotive is automatically put in the 32-speed step mode, with 1 chuff per revolution. Put the locomotive in motion and note where the chuff occurs on the rear driver. The next chuff should occur at the same location. Adjust the chuff rate up and down 50 numbers then 10, then 5 and then 1, eventually zero-ing in on the number. Master Chuff rate reset code determined, record the number for future use.
Selection the Chuff rate.
ENG+##+AUX1+AUX1+5 Each time 5 is press you will hear a series of whistles.
(1 blast) 1 chuff per revolution.
(2 blasts) 2 chuffs per revolution.
(4 blasts) 4 chuffs per revolution.
That should at least get you started.
Best wishes with your project.

It is interesting to note that there are chuff rates to be set for diesel locomotives
All of the TAS documentation is in the TMCC/LEGACY REFERENCE MATERIALS & MANUALS thread that's pinned to the top of this forum.

Ok, Thanks. So nothing to do with cruise speed? I was thinking MTH.
John thanks for the tach stripe sheet. Did not have that TAS reference material. I noticed the EOB I have has some slightly different plug locations. Primarily battery, AC power and Sound plugs. Did they have different instructions depending on the rev of the board? I am interesting to see how the chuff and puff works with a Lionel smoke unit. G
No, I did a quick read of the EOB instructions and I thought it was a programmable feature included on the board? G
It's an extra little module, it isn't a feature of the basic board.
Page 16 of EOB instructions clearly state the board has this capability. There certainly are a significant amount of chips on the mother board. This is an EOB Ver 3.0. It has smoke connections for element, fan, grnd and chuff. G
It does look that way, but I know the one that I have didn't function as indicated and someone told me that I needed another board. Mine didn't do anything with the fan output, just the smoke. I'm going to check one I have on the bench and see if I can get it to function like that.
Perhaps the only steamer I have with this has a broken board, maybe time to swap?
