Wink Free "Power Controller" for KTM test....



TESTING COMPLETE>>>>>


Anyone want to give it a try??? If your looking for a smoother throttle response.... this is the ticket..... Similar to the booster plug and the Accelerator.... but all done with a replacement sensor....

I have been building Power Controllers for the F800GS with great success and am now moving (testing) a unit for KTM models.


Picture is of the factory KTM air temperature sensor....



I have built a replacement air temperature sensor for the KTM 990. EFI bikes..... take the old one out and pop my unit in.
No extra connectors /
no external circuit boards /
no external temperature probe....

This drops the air readings by 37 deg F to give the bike more fuel to smooth the throttle response and give the bike more HP....

Later I will build the 2 position -36 / -18 deg F. model......

Here is a link to my BMW units....

I'm very interested. However, I do want you to know that I have a 10 990R and I have no complaints about power delivery or snatchiness. Do you think I would benefit? More importantly- is there a chance of damaging my engine? The BMW guys seem real happy.

Thanks for the question....

My unit is an alternative to the $169 Accelerator Plug....

Instead or writing all the details of how they work....
Please read up on the theroy of operation and decide if you would like to give it a try...



Accelerator....

Query

Make that queries ...

1) Static temperature drop across the board or remap the curve like the cycleops?

2) Any trouble projected when riding in cold temps? Took quite a ride last Saturday in 30 F weather and wouldn't want to "over rich" the mixture.

Thanks!

I'd give it a shot. I have a 2010 990 with Wings exhausts. Throttle is very snatchy (kind of fun though )

Anyone knows if the computer retards the timing if it thinks the air is very hot?
If yes, fooling it by dropping the readings could make you run with the timing too advanced at high temperatures...

Why cant you use just an inline resistor?

Is it worth doing if the O2 sensors have been replaced by resistors?

Thanks

the temperature sensor is a "J-curve" non-linear thermistor.

I have a few people on the list I will try to get the babies out this week!

No manufacture runs that close to "the edge" on a production m'cycle that it will make a difference................. ie putting a DNA air filter in will blow the motor (950)..... I don't think so. These motors are not that fast.

You may find it interesting that they are designed to handle 150 HP. I like your thinking though

The slightly richer jetting would contribute to cooler valve temps anyhow. These bikes suffer from bad aerodynamics in the cooling department and so give an impression of overheating....... an oil temp gauge will tell you what is really happening. I improved the air flow to the radiator it makes a huge difference....... have a look at sport bikes................

So if I only ride in 45F to 70F.... can I use just one resistor?
