I screwed up!!!!
Added an oil cooler to my 15 Fat Bob, engine guard, ventilator breather and did a crankcase vent system instead of going into the intake.
However I f'd up the ECM and can't test ride it until I get it back to the dealer.
From time to time I experiment with stuff and screw up. I always learn something but it can cost money. I call it entertainment tax.
I have a 13 Street Bob engine and ecm setting around from when I had a 120R dropped in. I keep the ecm because it had the Vigilante tune in it and I may instal the set up into the 89 FXR.
I had a brain fart and thought since it is not a stock tune would it work in another Dyna. So I plugged it into the Fat Bob. The LCD display announced "not the correct ECM". Okay. But when I plugged the original one back in it would not communicate to the engine. So, I have to take it back to the dealer to make it happy again.
So don't plug in a strange ECM it will upset the bike and it will not function.
Lesson learned. And yes most would not try that but I was curious.

When I worked for Volvo I had 3 different cars that needed transmissions so I asked parts to pull the transmission for the first car I had to do.
I gave them the PO# and they pulled the tranny and dropped it off at my bay...
Of course I didn't check the part numbers and installed the new transmission into the car.
When I went to program the TCM to the new transmission guess what happened?
..

..
Computer say...
"Wrong component mounted".
Yep, it was the first and only time I ever saw that message.
OP did you try disconnecting the battery for a half hour or so to see if that helps?

I pulled the main fuse for awhile then after putting it back I turned the ign off and on several times. I think I will pull the fuse overnight.
There should be some simple way to reset.

Most modern cars learn their ECM's as an anti-theft measure. It sounds like Harley's doing it now. Bummer for us gear heads!

People learn from mistakes. It's better to learn from someone else's but someone has to go first.

This ECM stuff makes me nervous. It would cost me quite a bit to fly my bike back to Anchorage just to take it to the dealership. I think I should have bought an old carb bike.
