Jardien pipes/PC3

[KingOfFleece]

So my bike came from the dealer with the Jars and Triumph tune 20228. From my research it seems like I need an aftermarket FI control-and the dealer works with Dynojet so it's PC3 for me. What do I need to know here? I'm not too sure the dealer has experience with this. I looked over everything at the Dynojet website-install looks stright forward enough-but any words of wisdom will help.

Thanks.

You might want to consider a Tuneboy instead. Price won't be too far off and there is a group buy going on at the D675 forum.

A PCIII is simple to install. You might want to remove the O2 sensor from the exhaust header and install an M8 oil drain bolt to plug the hole. That way the sensor won't get fouled and you can reinstall later if you need to.

I'd be happy to supply the pc3. My tuneboy should be here any day now! It would save me from posting it in the classifides.

How much, and why is Tuneboy better?

If you go to the tuneboy website they have a great comparison between their product and PC111. It is much more flexible and also works as a great diagnostic/scan tool for trouble shooting over many, many beers!

PCIII controls fueling only. Tuneboy controls pretty much anything the ECU does. So you can open the secondaries 100% and remove the ignition power restrictions. However, dyno tuning with Tuneboy is not practical in the US. A PCIII can dynotune on a dynojet dyno in about an hour and for around $250-$300. You can import a PCIII map into Tuneboy though.

On the site you can download the software and tunes for free. You pay for a cable and a software key to unlock your ECU.

Tuneboy is a program (~$400) that lets you change the tune in the ECU but you probably won't find anyone to dyno tune it directly with Tuneboy. If you bought this, you can download the 20028 tune from the Tuneboy site, open the secondaries 100%, and load this into your ECU. Then, you could rent (from Pig9r) or borrow a PCIII, install it, get the PCIII custom dyno tuned for ~$250, take the resulting PCIII trim map, use Tuneboy to insert the trim map into your custom 20228 tune, and download that into the bike. When you take the PCIII out, you'll also remove the PCIII O2 sensor bypass. You'll need to buy another PCIII O2 sensor bypass for about $20 and install it. Otherwise, Tuneboy supposedly has an option to turn off the O2 sensor on the bike, which is required for using and tuning the PCIII. You're final map will assume the O2 sensor is bypassed.

Before you spend the $600+, determine how you think the bike is running. You should also have the bike tested on a dyno to see what the air/fuel ratio is. It should be 13-14 across the rpm range. If it's higher, you may need to spend the money to richen the mixture with the above options.

The bike runs fantastic. Really quick-30 to 40 mpg depending on how I ride. I'm really just getting the PC3 or tuneboy 'cause everybody says to. BTW, we put 20226 in the bike and its runs the same but it's much cooler on the header side. Yes, i know they are warm but this is very evident that the 20228 was MUCH hotter than the 20226.
My dealer seems to think the 20226 is fine based on conversations with Triumph in GA, but you all have me a bit worried I'm gonna be too lean.

If you're running great with the 20226 tune and the bike is running cooler then you're fine. They're really not hotter than any other bike if you're fuel mixture is correct. Of course, being too rich would keep it cool as well.. You were running hot with the 20228 tune because it was too lean, but sounds like you're doing just fine with what you've got. Don't buy anything just because everyone says you have too. If you're dealer/mechanic is able to "read" your spark plugs, they should be able to tell from there if you're running rich/lean, etc.

The big thing.. If you're bike is running great.. Just ride and enjoy it!

If you DO decide to go with a PC-III. Keep in mind that all of the standard DynoJet fuel maps are based off of you having the stock R-III Standard tune (stock air filter/stock exhaust system) in your bike's ECU (Someone feel free to correct me if I'm wrong). The PC-III does not replace your ECU's tune. It simply adds/subtracts fuel to what the ECU is telling your bike to use, based on the fuel map loaded in the PC-III. If you're running the 20226 tune and you install the PC-III with one of their canned tunes, you will be adding even more fuel to the tune, which will cause you to run too rich.

The 20226 tune has the secondaries closing quite a bit throughout the range. That is how Triumph richens the fuel/air ratio, not by adding fuel but by restricting air. The numbers represent % open.
