......and the PC111 would make me nervous on the 07 SERK, just my opinion...........[highlight]Let's see a AFR graph from a 110 tuned with a PC3.[/highlight]

Here you go, a nice flat AFR line with a PCIII, rineharts, and a stage 1 AC on an 07 110". The point here is that its all in the tuning, a good tuner can get great results out of either the PCIII or the RT:

Easy Cowboys! Didnt mean to start a fracas over your PC1, PC11, PC111, PC111r/usb! I'll be the first to admit I know just enough to be dangerous ! I have a 2005 EG(95",SE203 cam's, RH TD, SE AC, PC111) and a 2007 SERK(SERT, RH TD, K&N). Both run great, SERT would be overkill on the EG and the [highlight]PC111 would make me nervous on the 07 SERK[/highlight], just my opinion.

Can you elaborate on why a PC makes you nervous on an 07? Is there something so different about the 07's that make the PC less capable?

And for those of you interested, I have attached a Power Commander map I printed out during my tuning process. There are 9 different throttle settings and 25 differend RPM bands for a total of 225 tuning cells for each cylinder, or a total of 450 tuning cells, although lots of them are not realistic Throttle / RPM combinations, like those in the upper-right and lower left areas of the map.

Any chance you can post the map?  Thanks,

Shoot GasRat a PM, This was his dyno.

[GasRat]

If someone could talk me through how to retrieve & download here I would be more than happy to post in the appropriate thread.

If you want to take a ride by i'll pull the map out for you. Or give me a call and i'll walk you through it.

[GasRat]

That would be great! I would feel a lot more comfortable with someone that knows what they're doing pull it, then my trying for the first time. I'll give you a call later to work out when. Thanks

The one point that is missing is that the Power Commander does LIE to the ECM to get the results it wants.   That being said the reason to go with a stage1 download in models where it is available is so that you dont have to buy the rev extend feature, you are able to at least get the bike somewhere vs. burning up a valve if the Power Commander dies.   I have had 2 Power Commanders die on me and if it hadn't been for a download I would not have gotten the bike home without a trailer.   Its something to consider if you ride in out of the way places.

Recently they did improve it drastically to compete with the SERT and other tuners out there with the additions of the tuneability of each cylinder, rev extender, timing of each cylinder.  The other nice feature is you can extract a map from it and upload / change a map while the bike is running.   The SERT does not do this.  John Golden is one of the best out there and there are a few others as well.

If the PC takes a crap, and you only did slip-on mufflers and a Doherty power pacc A/C, wouldn't the stock ECM be able to handle this set-up, without causing any more damage than a stock 110"? In other threads it's been stated that HD claims you can add SE mufflers w/o ECM mods, because of the O2 sensors. My understanding is that the '07's don't have any Stage I downloads or ECM flashes available. Thanks Harry. Hoist! 8-)

That is why i put downloads are only available in some cases not all.   Slip ons are again going to depend on the pipe.  Some have put them on and been way to lean and others have been fine.   Also remember the roadking comes with an open air cleaner where the ultra does not and it makes a big difference in A/F ratio.

Disclaimer applies here put it and try it with a dyno so you know the results.    I would probably tell you based on the heat issues known so far I wouldn't do it as a general rule of thumb.   Not saying it wouldnt work, but there are varying pipes / back pressures etc that you will need to take into account.

I was going to do a baseline stock dyno run to 4k RPM next week and then put on the PC and S&S SPO's with the stock headpipesand Dyno tune that to 4k RPM. You're suggesting doing another dyno run before the PC with only the SPO's? That's no problem. As I am still breaking this motor in, I am not taking it over 4k RPM. Would I remove the PC and dyno run again at WOT at the 1k RPM mark, or can I just do a WOT Dyno-tune at the 1k mi. mark with the PC? Thanks Harry. Hoist!

I am a member of the ThunderMax closed loop club. It doesn't get any better than that.

Lets everyone understand one thing clearly. IF you want to perform better, you have only 2 choices for PROPER running bikes.
A.  The SERT tuned well, or the

B. Thundermax.  Add to the Thundermax Auto Tune, and you have the best system available.

oh yeah, Disclaimer:  You make any changes you should really learn about how to do it. IF you made a switch to a PC and it takes a crap, you will be running hot.  On the other hand, if the SERT does the same, you will probably be on the side of the road with a Dealer to rescue you.  If you have the SERT, and then buy a Tmax, and the Thundermax loses it, just hook the SERT back up and go.  

The difference is that the PC and others like it, is that they are fooling the ecm.  The SERT IS the ECM, and so is the Tmax. Chances of a total failure with these are unlikely just becasue I said so.

When I saw how the stock afr line wandered on my SERK, I wanted the best harley fuel management system made hence the sert. I have been riding for 32 years and that was one of the leanest running ecm set-ups I have seen on a fuel-injected bike. Didnt want something that piggy-backed on the factory ecm base map. Not familiar with the Thundermax. The extent of the pc3 tuning each cyclinder is that you can trim the adjustments made for both cyclinders to vary by upto 5%(somewhere around there, I'm sure someone has the exact number) to account for afr variation.

I am still trying to justify a SERT,  would you please post your DYNO run with AFR ?

The PCIII Run in message Reply #30 above is the best AFR I have seen yet on an 07 CVO.  Thanks,
