I bought my bike (07 Street Glide) used. I am trying to figure out what brand tuner it came with. I have never installed one on a Harley so I am not sure where or what to look for. Only thing i know is that there is a plug hanging down under the throttle body that I was told was for the tuner.

So if you know what brand it is just from the plug, cool. If not please tell me where to look to tell which one I got. Thanks for the help!

 

You never mentioned how you know the bike has / had a tuner....
Does it have a stage 1 or a cam / big bore kit?
Some additional information would be helpful...
If they used a SERT or TTS then it is only attached during the actual tuning process and should have been given to you when you bought the bike. Power Commander and others like it stay on the bike all the time.

 

Look under seat, or in side panels to see if the control box is located there. Might want to post a pic of this pigtail too so we can see the connection...

 

The plug is for a California emissions component

 

I was told when I bought it had a tuner (when I asked what the plug was that was hanging down under the air cleaner). Hard to ask the man any info on the bike because the man I bought it from is no longer around. Long story, but I know the man and know the bike as far as it was not beat or anything. Got a great deal on it. The bike came with a full system and k/n air filter (now has a RSD Turbine). I bought the bike from a friend and he just paid the Stealership to do all his work.

I have the bike tore down for winter mods now and have not seen anything like a PC anywhere. I have not take both side covers off yet but will look there too. And it may not have a tuner on it. It may be a California emissions component hanging down as mentioned. But I would think it does with pipes and k&n. I assume that is what a stage 1 is.

I will take a picture of the plug when I get home. Sorry to seem so lost at this but it's my first Harley so I am learning as I go. I am not dumb, just new.

Thanks for the help.

 

If it has a tuner hopefully it's not the sepst or sert. If you don't have the vci (little black box) your SOL. It does not stay on the bike, but is a communicator between the computer and ecm. If you dont have that actual box, then you cant reprogram the ecm. You would either have the leave it alone or buy another tuner.

 

My 07 had that little plug hanging down behind the throttle body....I snapped it back in place.

Mine was stock when I got it but I can see it has slip-ons before me..I ave 3.5 rineharts and I think she needs some more fuel.

what to do what to do.

buy a pc111 or do a dealer tune?

I'm not even sure of my options to be honest.

 

My tuner is behind right side cover, cruise control and fuse box behind right cover.
