I would like to hear some opinions on what is the best way to go, Power Command or SERT. And benefits or drawbacks of each.

Well everyone on here knows I am going to tell you neither. I still prefer the Thundermax.

MG,
  I've had both, and have no complaints with either.  I'm running the SERT at present, with my 120.  Obviously, you would have access to hundreds, maybe even thousands more combinations with the SERT.  I think it took a little more dyno time with the SERT, too.  I can't comment on the Thundermax the DAWG mentioned, because I have no experience with it, but can assure you any Zipper's product is of the highest quality, and will produce peak performance.  Decisions, decisions.........huh?  Later--HUBBARD

This has been discussed here many times and the bottom line is that you need to talk with the local tuner that you trust to do the dyno and see what he prefers. There are a very few that do well with both. They both do pretty much the same thing and achieve very similiar results. There are pros and cons to both as well, The PC is a third party item that can fail and the RT leaves a footprint on the ECM that may cause you warranty issues to name a couple.

"The Dyno Jet Power Commander unit with it's 126 fuel adjustment cells and 126
spark timing cells offer simplicity that cannot always compensate for the high
demands of a modified V-Twin engine. Especially when the cylinders have a
different V.E. rate, this also offers a "Band-Aid" solution at best.
The H-D EFI Race Tuner Kit offers 220 Volumetric Efficiency adjustment cells for
each cylinder along with an Air Fuel Ratio (AFR) adjustment table that has an
additional 120 cells for a total of 560 fuel adjustment cells. There are also 220
cells for each cylinder to compensate for spark timing, fuel enrichment cells for
cold start and cranking enrichment for easier starting. With these extra tables and
cell adjustments there are over 1000 adjustments that can be made. Also
consider the advantages with having the ability to set your idle mixture as well as
idle speed and having access to your own rev limiter which is adjustable from
4000 to 7500 RPM. "

The Dyno Jet Power Commander does not alter the stock rev limiter. That is why
many people use the Stage 1 Download along with it. The Stage 1 Download
raises the rev limiter to 6200 RPM.

A small correction needs to be made here, and that is the fact that the Power Commander allows you to tune both cylinders independant to each other. You simple "Promote the Map to  Advanced, which gives you separate tables for front and rear.

The PC does not have as many cells as the SERT, but this usually means it will cost less to tune.

Six of one, half a dozen of the other.

If you are not interested in investing in an exhaust gas analyzer to do your own tuning, find a tuner you trust, and use what he likes.

You will be pleased with whichever one you choose.

Kojak2;
I'm not sure where you got your numbers from but the PCIII will allow 225 points of fuel and 225 points of timing for each cylinder. By my math thats 900 points of tunability. The PC is not a "baid aid" solution.

Also the PCIII will allow the rev limit to be set up to 6200 RPM with its "Rev Xtend" feature.

Just want to make sure that the facts are correct here.

MG,
I am currently running the PCIII on my bike until Zippers comes out with the ThunderMax that is ECR ready and then I am taking the plunge on that baby.  The PCIII will then be up FOR SALE.  I have a canned map in it now for a 2-1 pipe and my bike runs pretty good.  These guys on this thread know what they are talking about and the most important thing is to find a good tuner, even if you have to travel a few miles.  It will be worth it for you.

MG, where are you?  Some might have experience of exceptional (or not so exceptional) tuners in your area.  That's the first and most important piece of informatoin to gather before you proceed.

Besides the tuneability (is that a word? [smiley=nixweiss.gif]) differences between the SERT and the PCIII, there is one difference that may or may not be a point of contention.  If you have an '07 machine, the PCIII does not use the O²sensors and sensor eliminators must be used to fool the ECM into thinking that there are sensors present.  The SERT will recognize the sensors.  Based on what you read in here, that may or may not be a major point of contention.  Just something else you need to be aware of.

Guys,
Can the Dyno Jet be changed from bike to bike if I upgrade rides?
Thanks,

Assuming you mean the Power Commander then the answer is "YES".


 [smiley=xyxthumbs.gif]

[Mikey]

Woops,
That is a strong vote for the Power Commander for me. Just need to find a tuner
Thanks,

I've had both.  I ran a PCIIIUSB on the Ultra before 95" conversion, and it ran well.........until I started fiddling with it.  Then the ECM started throwing a code.  I have no business messing with stuff like that, and it took that lesson for me to learn that I need to leave well enough alone.  When I had the engine converted to 95", I had a set of V&H Big Shots Long installed along with a SERT and a "canned" map for the break in period.  After 1000 miles, I brought it back for a dyno tune.  I was very happy with the results.  I'd do either again, but I think it is a good idea to have a Stage 1 ECM flash if one is going to use a PC, because 1) it raises the RPM limit to 6200 rpm, and 2) if the PC ever fails, you have that map to fall back on, so you're no running so lean that you burn up your motor.  As for all the tuning brouhaha, I'll leave that business to those who do it well.

I have three good videos of my SERT dyno tune, but they a HUGE.......7MB to 11MB.  Can't post 'em here.

That's a "yes maybe."  If Harley changes the bikes the Power Commander changes to match it.  They are also specific to model families just because of the differences in mounting (if nothing else, thought that's not always the only difference).

So, for example, the Power Commander that fits my 05 SEEG fits several years worth of touring bikes.  But it won't go on an 07 because of the changes made to the 07s.

So yeah, you can swap them; if it fits the bike you're swapping to.
