Quote from: hrdtail78 on November 20, 2023, 08:49:00 AMBeen a couple years but I converted a 02 to a closed loop system.  I changed ecm.  Married it, and ran the new wires for sensors.  Then tuned it with a 176 level cal.

Great. I may be in the need of your assistance getting a couple builds dialed in. I'm just down the road from you in northeast Arkansas 👍.

Did you ever get this going?  As a few others have mentioned, You could easily convert that bike to use o2 sensors.  BEst route imo is to get a few parts from an 06.

I recently ( 2 years )did this to my 2001 Road King.  I had a secret weapon though, the Guidence of a senior Forum member for part fitments. I documented most of the process over on CVO harley I could probably also move that over here.  It's.. kind of a guide.. in ways.  I got most of my parts from ebay, i think I spent around $500, most expensive being the fuel pump.( Not including the tuner and o2 sensors).  Just to name a few parts you will need, Fuel pump, Speedo, throttle body, injectors, o2 bungs, o2 sensors, ECU etc.  If your mechanically inclined, its a pretty easy straight forward process.

I went with the TTS Master tuner route. and did my own tuning.  YOu can build a base map in just an hour. Or i could share mine.  Runs amazing. So happy to drop the Magnetti Marelli system. 

Agree with Ohio on getting a proper dyno tune done, not that I think you couldn't get it better yourself but going by what you have stated it would be quite a learning curve for you to get there, if you have the time then fair enough but road tuning is not as easy as some would have you believe.

Throttle sensitivity can be changed. So much so that it can become too sensitive to ride smoothly. There are settings that can be changed with a tuner.

There are throttle adjustments that can be made in software on drive by wire systems.

2013 Electra Glide Classic. The free play is there is slack that needs eliminated.

Is there any way to adjust throttle free play out of thes fuel injected bikes like you can with carbureted bikes?

If I would have known that , I would have gone further with the procedure. I mearly went with the instructions and picture. It's now back together and everything seems fine. Thanks for the info just the same.You cannot see attachments on this board.

You may end up having some success doing that. But in the end I think you need to have a proper dyno tune. If you look at the dyno sheet in the link below, you are down quite a bit from what the 120ST should give you. He also has a really good exhaust system.

2013 Ultra Limited with 120ST. I'm not sure how the right way to describe the issue, but here goes. Mainly when hot the engine kind of lurches every 3 to 6 seconds. Raising the RPM's up to about 1100 makes it a lot better. I had the bike dynotuned, but I don't think the tuner knew what he was doing. Power wasn't too impressive 108 hp, 118 torque.
ever since I had it tuned (about 3 years) I've had a lot of decel popping. I fixed that by watching videos on youtube, so now I want to see if I can take care of the hot idle issue.

The fuel mileage seems to be too low, so I'm thinking maybe I need to lean it out some. I've got a Power Vision so I was thinking about just using the quick tune and lean out the lower RPM by 1% increments.

Does that sound reasonable? If I change it about 6% and see no difference, I'll probably just go back to 0% and try something else.

Below, #14 the shims, this is where they get placed.
