This by far has to be one of the most controversial topics when it comes to increasing horsepower gains using the Power Commander III.


What are the 3 buttons for, how do I used them, and should I be messing with them. All very good questions.

 

There are many who believe that the three buttons on the PCIII do absolutely nothing and the gains when tampering with these buttons are purely psychological. On the other side of the spectrum you have those special individuals who believe that these buttons work, but tinkering with them, specifically  your air to fuel ratio, should be left to a trained professional sitting behind a dyno tuner. I have to disagree with both and believe that Dynojet knew exactly what they were doing when placing these buttons on the face plate for the consumer to tinker with on the fly. No one knows your bike better than you and just like you know or feel when there is an issue, you will also notice when there is a performance gain despite what other may say.


For those interested in adjusting your PC III blind and on the fly I'm including the directions below for you review and knowledge. For those interested in the sweet spot that I found to work best for me, take a looks at my YouTube tutorial and pay close attention to the level adjustments for each and make your adjustments accordingly. When performing these adjustments blind and on the fly take note that with each minor adjustment, you're going to need to take your bike out for a tet ride to see what works best for you.


Tweaking PC3 for Increased Horsepower





To adjust the buttons on the faceplate of your Power Commander III, follow the instructions below:

-With the ignition off, hold down all three buttons on the Power Commander III unit.

-While still holding down the buttons, turn on the ignition and start the bike.

-Release buttons. The light(s) should show up in the last place they were left, by default the center two lights.

-Select the range you wish to adjust: Low, Med, High by pushing the corresponding button once, (these ranges are determined by taking the bikes RPM limit and then dividing it into thirds).

-At this point holding that button down will move the lights down (leaning out the mixture).

-Pushing the button repeatedly will move the light up (richening the mixture).

-When the two center lights are lit up this is the “0” setting.

-After making your adjustments wait 20 seconds before turning it off. This allows the settings to be saved to memory.

 

Keeping your bike cool is the name of the game if your looking to increase horsepower gains. 


This can be achieved in a few ways but none is more simpler and straightforward then adding a second fan. 


In this video tutorial I walk you through the steps I took  to add a secondary fan to my bikes radiator to keep the bike extremely cool during blazing hot summer time rides. With the addition of a manually controlled switch to operate both fans at my will, rather then waiting for the ECM's mapping system to figure out were running hot I now can keep my bike in the sweet spot for cooler rides and best performance gains.


Secondary Fan Mod (Keeping your bike extremely cool!)

 

This diy tutorial is a 40 minute project that will allow you to incorporate a manually controlled toggle or rocker switch to switch on the bikes cooling fan when you want.


In a typical condition, the fan is electronically controlled by the mapping program within the ECM and is switched on when the coolant temperature reaches 225 degrees within the radiator. This high heat condition greatly reduces performance and makes street riding practically unbearable at times if riding in especially high traffic condition or where stop and go is present.


This mod will allow you to cool the bike when you want while still retaining the same 225 auto kick on it was designed with.

In this video I show you how to troubleshoot the c32, c33, c34, c35 error codes that are associated with the fuel injectors of your motorcycle. 

This issue is not solely consistent with just the Power Commander, in fact it will also occur without one since the problem that I was encountering was related to a dirty connection at that kickstand safety switch. 

Since the Power Commander is a fuel management system I initially thought that there was an issue with the cable wiring or unit itself giving me the fault codes after receiving a quick jolt from freeway bumps. Quick/Sharp jolts combined with broken or loose connections is often the culprit of sudden failure blurbs.

A side from the FI indicator and codes being thrown other indicators may be a sudden loss of power or complete engine stall during your ride.

There are many reason why you may be thinking about purchasing a Power Commander. Increased horsepower, fine tuning your racing machine, addition of some aftermarket parts or maybe you just want to dive deeper into your knowledge. ALL ARE VERY GOOD REASONS.


As for me I recently purchased a new motor with 1,600 miles on it. With my previous bolt-on mods of a Yoshi Exhaust and K&N Air filter this made my new engine run lean, thus making the exhaust piping extremely hot (more to it than that but you get what I'm saying). With heat pouring out from the piping this made street riding unbearable. In fact the heat was so bad that it began to warp my cheap Chinese fairings and discolor/bubble my paint.


Now, don't get what I’m saying about heat confused. The pipes were heating up due the lean condition, not the engine, the engine ran at its normal operating temp and never overheated. The only way to richen out a lean condition is with a fuel manager such as a PC3.


2020 UPDATE

For those of you looking to download a map for your motorcycle Dyno Jet has updated their website and you must NOW register in order to see any maps. Once you have registered with the site, log in and go to https://www.dynojet.com/tunes and put in your bikes information in the 5 boxes located just under the picture titled "Tunes" and click go.

Your bikes maps should populate and under the downloads column you should see the maps for you modifications. If you see login in this section then you are not logged in and must do so.


For my 600 folks looking for a map you will find it under "Power Commander" dropdown AND NOT "Power Commander III USB". The pages are limited to only 10 maps per view and there is a total of 3 pages, so if you don't see your map on the first page be sure to go through all 3 pages.

Part two of this series runs you through the install process I took to get my PCIII in my bike. As you will see there is not much to it but there are a few things to remember when performing this diy which I have outlined below.

*Never pull from the wires of any of the connectors.
*Make sure you always check and insure you have the black connector of the PCIII in the right orientation.
*Always listen for that CLICK sound when making your connections
*It doesn't matter what side you run the PCIII harness on. The right side had more room for me cable wise and made connecting the battery ground easier.
*Use a "RED" T-Tap and don't kill it when crimping it closed.
*The TPS signal wire color is PINK with a BLACK STRIPE.



All information about making on the fly adjustments using the 3 buttons on the front of the PCIII can be found on the download section of the power commander website. You can also find a guid on this site relating to the 3 button configuration I took if your interested.
