ERR upgrade for TMCC steamer

Actually, I believe the consolidations made by Lionel were 1 chuff/rev locomotives.

As John said, the upgrade to cruise is very easy.  I upgraded my Lionel 2-8-2 with that kit and the install took about 15 minutes.

I've done the ERR upgrades on Atlas and K-Line but only on diesels. I suppose the the process isn't that different on a steamer. Would the components be in the engine or the tender? I have to ascertain if I can do the magnet and reed switch conversion on this baby as I'm a stickler (not necessarily to my credit) about accurate chuff rate. (I use a lot of slow motion). I have three choices for a purchase - one on line, and two in local shops - big price variation from $395 to $500.

Could be, I know it's very unlikely to have four.   I don't happen to have one of those.

Diesels are very easy to convert, steamers typically take a little more work.  You have a few extra things to deal with:

The tether, as usually you have to put some or all of the components in the tender.

The antenna, most of the stuff you'd be converting has metal shells.

The chuff switch.

Those typically run up the time to do the steamer conversion.

Miguelito:  I am wondering if you completed the Consolidation project?  I bought a Lionel PRR consolidation 6-28086 several years ago and it has one chuff per revolution.  I had a lurching problem with the loco so I decided to have ERR installed by a local tech.  He installed the ERR unit and I just got it back a few days ago.  It works fine but the tech did not do the 4 chuff fix.  I am not experienced in the electricals in the locos but I might try the chuff fix myself.  I just need to know where the smoke unit wires are to connect the cherry switch.  I need to find out the best adhesive to mount the cherry switch to the underside of the loco.  Have you changed your loco's chuffs?

If there's a cam to activate the chuff switch, take a look at the mods done by Alan here to build up four lobes on the cam to activate the four chuffs per/rev.  Did the TMCC conversion include chuffing smoke?  If so, what TMCC boards are used for the conversion, ERR or perhaps the TAS boards?

I had the ERR module installed but it did not involve the chuff unit or changing the smoke unit.  I don't use smoke.  I have read about adding lobes but that might be beyond my capabilities.

The easier way is to trigger the chuff from the tender and put two magnets on the wheel for the reed switch trigger.  That results in pretty close to four chuffs/rev as the drivers are about twice the circumference of the tender wheels.
