It is a replacement ecm and programable with an auto tune feature. You don't need a dyno tune.

 

Notised if I was in 6th and tried to pull up on the shifter the 6th gear light would go out, I would shift back to 5th then 6th and it would come back on.

 

The 6th light thing is associated with then engine speed. I have the latest firmware and it was after loading it that the tach/speedo thing happened.

 

Today my speedo started "dancing" back and forth between 35mph, and 80mph. It's done this before too. It would hold steady for a second, then start dancing. This made the cruise control inoperative, and the automatic volume control on the radio go up and down too. Like the others, I had to pull over, shut the bike off, then restart it. It seemed to run okay after that.

I didn't know there was a firmware update for that. I hope it comes out soon.

 

Sounds like the thing's running on Windows. Yikes! I'm definitely going with the DTT...

 

Been running a T-Max on my Wide Glide for some time now. Haven't had a single problem with it. I will take the T-Max with auto tune over anything. Got a lot of friends with the T-Max on their bikes too.
It makes it run that good.

 

Cowboy Harley is suppose to be taking my Thundermax with A/T off my 07 Wide Glide. My 08 Electra Glide Standard has Drive By Wire. I called Zippers and they told me that they are working on a software update that should be out sometime after the 1st of the year to fix the DBW problem so I can use it on my 08 bike.
That is just what I wanted to hear.

 

Yep... It's happened to me twice now with the "new and improved" 4.5 firmware.
I've submitted the problem to Zipper Tech Support.
