Thats the truth!!!They sure dont work with thunderheaders!!!
Seems to be geared towards V&H products only!

 

theyve got map for thunderheader.

 

I sure don't have that take on it. Seems to be relatively popular "around these parts." The thing I really, really don't like about it is they have the hood welded shut on it. I'm sure they mainly want to protect their intellectual property and I guess that's fine, but it's not my style. It's the same sort of mentality that Microsoft has. I'm a GNU/Linux person. I prefer stuff that I use day and and day out, and stuff that I trust my money and other stuff to, to be open for inspection and/or modification, or at least to be configurable in ways I want to do it, and without having to get a "by your leave" from someone (even if that means to call them and ask what combination of arcane sequences to key into the panel). If V&H were wise enough to release the information on what those settings do and how they interact with each other and the engine I'd probably use the damn thing.

The P and the C are Power Commander, an offshoot of Dynojet Research. The folks who make the dynos everyone uses. They have tuning link software which plugs into the dyno and into the PC-III to automatically tune the PC-III via computer. I've not done it because the canned map I got for mine from Fuelmoto works quite well (with a couple modifications by myself), after discovering our '07 Delphis have adaptive fueling and that I needed to reset my AFV after having ridden around with just the slipon mufflers.

I believe mine was about $275 from Fuelmoto.

The V&H, the Dobeck stuff (Arlen Ness, Kury, Cobra, et. al.) with the three "pots" or buttons, depending on generation, are all fuel-modifiers only. I don't know whether V&H can remove fuel but am pretty sure the others can only add. There's the (rather expensive, and snake-oilish, in my opinion) Terminal Velocity II, which autotunes. Maybe I'm leaving something out so far, but the common denominators are they're all piggyback devices which modify fuel only, not spark timing.

You've got the PC-III which is also a piggyback, but which will modify fuel and spark timing in both directions, as necessary. It requires the use of a computer (Windows-laden; yuck) to set up initially and to modify in the finest grain. You can also do both fuel and spark individually per cylinder if you so choose. You can also increase the rev limiter from 5500 to 6200 with the PC-III; as well, there's (not so needful on our slow-revving v-twins) an "accelerator pump" feature which is very fine-grained adjustable. There's some other feature I don't use, too, but can't remember what it is; oh yeah, starting fuel addition for large engines. You can also trim cylinders front-to-back in a simplified manner even when configured for non-separate control of them. There are three buttons right on the unit for gross adjustments just (I assume) like the Dobeck and friends do.

I almost forgot. When they initially developed the H-D version of the PC-whatever, it worked without a hitch. Now, H-D has changed some of the wiring or functionality of the power circuits the PC uses, so if you turn on the ignition and wait for the fuel pump to quit spinning before you crank the starter, there will be a minor delay in starting. What's happening is when the fuel pump (and coil and injectors) lose their power about 3 seconds after turning on the ignition but not thumbing the starter, the PC also loses its power. When you thumb the starter all that stuff comes right back on, but the PC must go through its startup routine (it must "boot up") again. This is the delay. If you thumb the starter while the fuel pump is still spinning

 

Don't think so... I have set-up a few Putts using V&H FuelPak with RHTD - Samson & Bassani and never had a problem yet???

 

I have a PCIII and it works great . . . however the mount is really cheezy. You wire tie the damn thing to the top of the ECM. I've heard that the fuelpac actually has a mounting bracket. I hate the way the PCIII mounts. Looks like $hit hanging there like that.

Glens,

You are the man when it comes to explaining things to us newbies. I think I'll spend a couple weeks going back and reading all your posts. Thanks for being here and thanks for all the help.

Well, when you have been riding for 30+ years, you DO get a little knowledge about these things....

 

Thanks to Y'all,

That was some wonderfull feedback.

I will go with the V&H Fuel Pak, I'm not going to do any other Mods to my bike beyond the Exhaust and Air Cleaner.it is amazing that the $400 a month I pay not only got me a great Bike, but I'm also getting a family. Reading all y'alls post has really helped me out.

His and Her's....or shallI say 2 for me.
Ron
