I was reading Keefers review on the KX 2021 and he suggests a map to increase pulling power out of area 3 of corners as well as give you more mid-top end stretch in 2-3rd gears.
He already posted the same map twice, 1st in october and now in late november. The first time he said to use the black coupler with that map, now he is saying to use the green coupler, but the maps are exactly the same.
Does it make any difference what coupler I use, considering that I'm changing all fuel and ignition settings?

When you change the settings, say you have white coupler installed and you apply that data. Now the white coupler is whatever you just did, You can change the green coupler settings to whatever you want too and the white and black are not affected by it. So you do have 3 different "maps" to choose. I think it's best to leave green alone at all zeros then you can make 2 different maps with black and white and have the original green map to compare to.
I'm not sure what Keefer was saying about which coupler to use with his map. You take those settings of his FI and IG maps and apply them to whatever coupler color you want to use. The remaining 2 couplers will be whatever they have previously been programmed to and have no bearing on his...
The manual that comes with unit is convoluted and redundant. it seems like it goes on and on and its not specific as to how couplers work, that you should select what coupler you want to apply map to. Someone could probably make a good procedure that fits on one page that is simple and easy to follow.
The couplers are just jumper wires that tell ecu which data (map) to use. The green is also a jumper. If you have nothing connected it defaults to green map though. There must be a coupler installed to connect to FI unit.
Hope this might clear up some confusion.
When you load up the factory white or black map does it show the factory settings to those couplers or does it show all 0s?

Now that I say that, I have no way to prove it. If you don't have a coupler installed at all, the cal unit will not connect to ecu and give you a fault. So you can't see exactly what's current in ecu without a coupler. and if you unplug coupler after connection, the unit will fault out. So the calibration unit has to see a connection to connect and that's probably why the green coupler also has a jumper.... if any of that makes sense...
What I could do is make a hideous map and program it for the green coupler. Go ride it and see how it feels. Then unplug it and ride it again. If it feels different, like back to all zeros green coupler feeling, then that would indicate that it does revert back to all zeros with no coupler installed. The manual does say it defaults to green map with nothing connected but doesn't say anything if that holds true after green map is changed.
The black and white couplers are not all zeros from factory. they have changed data. When Kawasaki's Mike Chavez came up with his map for Keefer and the magazines he used the FUEL setting from one coupler and IGN settings from the other coupler and put them on the green map (I think). If you used white or black after that they would still be as they originally were with no affect from changed green.
I don't know why MXA and others call black mellow and white aggressive. The black has more low end power and gives up top end. The white gives up low end but has more top end. Kaw themselves refer to them as hard surface or soft surface... It gets confusing...
Appreciate the info!
Is there a company that - for a fee - can flash the ECU to the 'Chavez' map that is constantly mentioned? I don't want to buy the calibration tool just to upload a single map.
Just getting back into dirt bikes after roadracing for the last decade, and there are a ton of companies that can flash an ECU depending on what you're trying to do. Would love to pay a one-time fee to do the same thing to my KX250 for a more reasonable price than purchasing the official calibration tool.
It seems like Kawasaki themselves would offer this service.
Tokyo mods wants $200 to re map. But I'm sure they will insist that they have a better map...
The roadracing bikes are a lot more, but those are typically custom tunes with lots more options / variables to tune.
I am less than 30 minutes from Pro Circuit and have my suspension there right now, and I need to pick it up next week. I might be able to have them do it as well!
