The Chuff-Generator (C-G) is an add-on electronic module for TMCC controlled steam locomotives to replace mechanical chuff switches. It also supplies a programmable chuff rate locked to driver rotation
The C-G can be installed in factory TMCC locomotives or TMCC upgraded locomotives. This is a microprocessor based design that allows for software updates to accommodate functional changes and possible future enhancements. The C-G is mounted on the motor and reads a tach tape on the flywheel to measure relative distance and determine relative speed. An optional output for ground light control is provided; the ground lights will be extinguished at approximately 10 MPH and lit at other times. The MPH calculation is based on an average gear ratio and driver diameter and may vary between models. The C-G is fabricated on a printed circuit board with the dimensions of 1.3" x 0.4" in size. The overall height including components is approximately 0.125".

Well now when you have an early scale Lionel J that had no puffing smoke unit and 2 chuffs what do you do? You buy a Super Chuffer board and a Chuff Generator board and make it into a new locomotive. I bought both of these at York and installed the Super Chuffer about 4 years ago. It gave me the puff with the chuff but it still didn't look quite right after running Legacy engines with 4 chuffs. Along comes the Chuff Gen board. I installed this carefully following the instruction and wow! What a difference. I have a new engine!
The proof is in the video. Remember this engine didn't even puff when released. Now I have 4 chuffs per revolution and 4 puffs! The only change in the smoke unit was removing the resistor cover, expanding the intake hole, re-wicking it with the Lionel "rope" and using Lionel premium fluid. Bottom line this is an awesome product!
We perform a lot of Electric Railroad upgrades. I installed the Chuff Generator with a Supper Chuffer that was supplied by the customer in his locomotive with a Cruise Commander and Sounds. It works great. This is a nice upgrade to any engine with a DC can motor with a flywheel and a fan driven smoke unit. It is not difficult to install. I highly recommend the kits.
