Just wondering if anyone has had any experiences with these. Any recommendations. I have owned Carbed harleys which I jetted and tuned and they ran flawlessly with the same milege or Better than my friends Fuel inj bikes.No popping or coughing.I now own an 05 CVO FLHTC which is fuel inj. I plan on changing Cams to andrews 37 with newer style tensioners. If I can buy a Good IGN without getting it dynoed ,id be thrilled.

 

To get the auto tune feature usually requires 18mm O2 sensors and I believe your 05 has them. I use Dynojet power Commander stuff in my '03 and '13 fuelies. My '03 does not have bungs so Autotune is not an option. I installed V&H Power Duals for '09 which have the 18mm bungs on my '13. Should I ever get too far away from stock on the '13 I will add the AutoTune to my PC IV. There are better options available

Power Commander Power Vision and Thundermax are some of the newer AutoTune modules and I believe both require using an 18mm wide band O2 sensor.

 

Power Vision still works with the standard sensors, not quite as well as with wideband but pretty good.

 

HD's are equiped with narrow band O2 sensors. The HD ECM will NOT work with wide band sensors. In 2010 the unheated 18mm were replaced by heated 12mm versions and moved further from the heads. They both perform the same. They signal a rich/lean condition to the ECM so it can adjust the fuel injection pulse for minimum emmisions. No difference. Since dyno's can monitor engine performance data beyond just rich/lean conditions, adjustments to ignition timing as well as fuel delivery can be made to optimize power. That's using the HD ECM. If you discard the OEM module and go for a complete after market replacement using wide band O2 sensors you'll still be faced with how to measure power output changes due to tuning. Seat of the pants? Bottom line is that you'll get improvements from the "auto" tune features. But you'll get more from a dyno tune. It just depends on how much you are willing to pay to get as close as you can to a "perfect" tune. JMHO.

 

Self learning Ignition modules on a harley is a myth. Closest thing is Thundermax. Nothing beats a proper dyno tune.

 

It's true that nothing beats a dyno tune but my RC Xcelerator has performed flawlessly. I'm not drag racing though, just riding on the street so I'm not concerned with the last few horses I can squeeze out - I just like the bike to run very well.

 

I am also looking for a good running bike ,not too worried about a few extra Hp that a dyno will bring.

 

I don't understand the notion that a proper dyno tune is all about hp? It is about having a proper running engine!The fact is, anti-dyno folks either don't know what it is or are too cheap to do it right, maybe both? Sounds like "settling" to me.

 

Good point. A well tuned engine will be more reliable, have fewer carbon deposits, will operate at a lower temperature, and produce power levels closer to its full potential.

 

Installed the RC xcelerator bike seems to run better a little better gas mileage have only put on a few hundred miles will let you know
