Before using this map (or the Gen II version) or any other map in your PCIII USB unit, it's important to first set your throttle position using the PCIII USB software.

Download the map to your PWRCMDR library under Yamaha or where ever you want just making sure you can retrieve it using the Control Center software.

Note: The current map in your PCIII will not have a name. It will be called "untitled.djm". This is normal, so you might want to save it as something to make sure you can re-install it! If it's the stock map that one is available, if not save it.

In the Control Center software, with the bike running and connection established, select open map using the tool bar or the big button on the left. Select the downloaded map from a list presented. This is the normal everyday method you have used before.

Next, send the map using the insert key or the big button on the left. That's it. Close the software; take the bike for a ride.

The M409-MF008 map uses the foundation of several available maps that were mathematically combined trying to get the best of all worlds in terms of power, mileage and smoothness. I then took that base map and loaded it in my PCIII USB unit, put the FJR on the dyno and spent lots of time mapping cell by cell to an air/fuel ratio range of 13.2 to 13.5 from 5% throttle at 1500 RPM to 80% throttle at 6000 RPM. I then tweaked the 100% throttle numbers from 3000 to 6000 RPM. I'm a fanatic about perfect throttle and low RPM manners so the tweaking reflects this. I'm also wild about decent mileage and this map should provide that, or it should be no worse than what you have BUT all bikes are different. It could make your mileage worse or provide the incentive to use the throttle more and make your mileage worse. You be the judge. I did not tune this map for top end power. Don't expect any.

My bike with this map is dead-assed smooth; the throttle is to die for — the bike lags nowhere and picks up power from any RPM at the snap of the wrist. I hope it's the same for you.

This map does have some changes to it which will allow for mass adjustment using the buttons on the unit or the software and your computer. This means that you can tweak it some to your bike but I will add this disclaimer; Do not add or take away a value of more than 3, meaning three clicks or 3 stabs at the Page Up/Down keys.

To make changes, you can use the buttons on the surface of the unit and change the low, mid or high RPM ranges. This affects a great many cells and I will refer you to the instructions that are online or should have accompanied your unit. In the software you can highlight the cells you want to change by clicking and holding and dragging to expand to the number of cells you want to affect. Then, use the Page Down and Page Up keys to make the changes, stab the Up key to lean it out (take fuel) and the Down key to make it richer, add fuel. Each stab equals a value of one. A value of one equals approximately one tenth on the A/F ratio scale so three stabs equals three tenths of difference, or pretty close anyway. Always hit the insert key to upload afterwards.

Food for thought — the area from 0 to 20% throttle encompassing 0 to 4000 RPM is the range that the EPA looks when testing and will be leanest from the factory, in most cases. This is also the area that most tuners spend the most amount of time in when mapping. This is the area that gives great throttle.

Any questions? Email me for the best and quickest response. Please don't email me just to tell the map sucks. It very well might in your bike. No guarantees. I sincerely do hope it helps though. Ride safe.


P.S. Here is another map created by my business partner Bill for his bone stock FJR. I have no experience with it, have never ridden with it but in doing a compare, its interesting. Remember that mine has LV cans and they must reflect some change to the air curve or its just the difference in engines — dunno but we mapped for the same targets, ie., 13.2 to 13.5 A/F ratio and from 4000 on there is almost no difference in fuel curve vs. throttle but there are minor differences in the numbers. Very minor. Larger differences from 1500 to 3000 rpm. Anyway, it might be interesting to some...
