Ok so I took the plunge and ordered an At-100 Auto-tuner for the PC5. I have an 03 Road King Classic. I have been mulling this over and over and talking to people on here and elsewhere for advice. My skoot runs pretty good now but I thought after putting in 510 cams I would feel a noticeable difference. I feel just a little, very little and dyno tunes are out of the question from where I live let alone this is a touring bike, not a hot rod. I've seen them do the dynos and it cant be all that good for the bike if they have to do multiple runs. So I guess I will see if the money I'm paying is worth it. $625 Canadian. Ya I know. It should be here in a week. I was considering trading my bike on a CVO of the same year but a lot of people said to keep what I have as I know what I have into it. I'll let everyone know how it works out.

A big myth, Dynos are not bad for the bike.

 

Keithhu, that may be true but I have seen dynos done on bikes and yes winding them out all the way isn't much worse than doing it on the road, however what I have an issue is when they let off the throttle and let the engine pull the revs down rather than just pulling in the clutch. I have never done that on any bike I have had whether it hurts them or not, not to mention giving full throttle in high gear off of idle. I seen that don't once and you know that's not good for it.

Whatever. People that are expert tuners disagree, but we live in an era where experts are shunned.

 

You will love the Auto Tune Pro! I just did the Target Tune kit for my 2007 EGC with the FM107 big bore kit. I had FuelMoto do the 107 build back in 2015 and the TT wasn't available then. When it came out it was $699USD! My bike was running good, Jaime and FM had dyno tuned it. How much better could it be?!

But, after now my 3rd season with it and zero problems, one of the stock 02 sensors went bad. Jaime had told me that the stock sensors on the first gen bikes weren't all that good in the first place compared to the later ones HD came out with, so he did expect I'd get some ping now and then. So I checked the FM web site and the price had come down to $399 for the TT kit. I decided if I was going to replace a sensor, let's do it right.

I couldn't be happier with the results. Installation was easy, and the bike just runs better. At the low end of the spectrum the bike handles low rpm, below 2K even, very nicely without complaining. I can give it a lot of gas and it just grunts and goes. The higher RPM is just amazing, the bike just spins up faster and with even more torque than I had before. 3 gear is scary fast!

It even sounds smoother! A fixed tune just isn't as good as a self adjusting closed loop system that is constantly, accurately monitoring itself and adjusting. Add to that small differences in temp, gas, etc, it's just a better running bike.

This is going to be a major improvement for you I think! What pipes are you using? You need the 18mm sensor bungs. Also for install you need a standard 7/8ths automotive sensor socket. I got one on Amazon for like $12USD. You'll also do well with a long ratchet extension and universal swivel to get at the possible difficult angles for the sensors. My old ones came right out easily enough and the new ones went in easy peasy. It helps to have someone on both sides of the bike to pass the wiring through but not a big deal if it's just you. I didn't put the bike up on the lift, it was fine on the garage floor on it's side stand. Have a lot of small and long tie-wraps. for the AT module and the cables that I brought along the lower frame back to the AT module. Use a large paperclip end to piece the membrane to insert the wires into the AT Module.

Let us know how you make out!

 

That is one SWEET ride you have there, if it was mine I'd hold on to it.

 

So you're wide open in 3rd then it's time to brake for a corner and you hold the clutch in rather than letting engine braking do it's job? Interesting technique....

 

Cajun, what head pipe are you doing with, I don't think you want to use the stock set up you have in that picture for the sensors. Make sure you have a head pipe that accepts 18mm sensors.

Fuel Moto is the only one I know of that actually makes and sells a 2-1-2 head pipe that goes under the frame for pre 2009 bikes. I'd definitely be looking at that for your bike. Did you buy the Autotune kit from FM? They'll pre load an good starter tune which you'll want for the PC5.

 

I love the way mike bike runs after I added the autotune to it. noticeable difference

 

Having a good basemap for your bike/combination is crucial...

The PC-V / Auto worked well for me for a few years...
