• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

PC V with Auto Tune = Holy Grail. for the 2008 & 2009 Husqvarna EFI bikes

So $600 hmmm, ouch. But there would be no need for the iBeat stuff after that? ...

to be able to tune the bike correctly it`s a good idea to ensure all factory settings/faults are correct first, only then can you accurately tune/trim........for that you need iBeat. Small inconsistencies will be able to be "feathered" or covered up, but if you can`t read/set the starting point, it may not be as good as it could be.
And when they are 100%, they are absolute ball tearers
 
When setting up the PC-V + Autotune on a Husky does the Throttle position function work or is that only for certain kinds of bikes?
 
Nothing is done to the Throttle Position Sensor. That is a fairly important item to keep. The TPS wire does need to be connected to the PC V.

In addition to the TPS connection and ground, the PC V connects between the injector and harness that used to connect to the injector and adds/subtracts fuel based on a 'map', that map can be made by the Auto Tune which connects to the PC V.

Both the bike ECU & Power Commander need to accurately know what the throttle position is.

The ECU calculates the required fuel from TPS, manifold pres., RPM, air temp, atmospheric pres., O2 sensor (if installed) and engine temp.

iBeat is used to calibrate the bike ECU 0% (idle) TPS position, Power Commander software is used to calibrate the PCV to know what 0% and 100% is.

PCV makes additional adjustments to the ECU's fuel command based on user editable correction % for a give TPS & RPM. Further adjustment is made based on user editable AFR for a give TPS & RPM if the Auto-tune O2 sensor is installed
 
Here is what TPS wire near the ECU looks like on a 08 TE450.

I made the tap by removing 1/4" of insulation and soldering on a tap wire, then covering with RTV and tape. The end of the tap wire has a 1/4" blade quick disconnect that mates with the PCV connector.

Perfect tanks!

The instructions that came w/ my PC-V had me tap into the Orange Wire, not the Orange/Black.
 
O YA i just got my PCV and auto tune kit today! i can't wait for Sunday when i can install it! thanks a lot to scott from semcodesigns!
 
I didn't like how they have you mount the units to the side numberplate w/ velcro so I made a triangular shaped panel out of a piece of LKydex I had and zipptied the PCV and Autotune in the open area of the frame on the right side of the air filter.

This way all the wiring and the units can be securily and permanently fixed to the bike.

Will post pics when I get a chance.
 
This is really helpful for those who need to tap in! Good on you man!

i installed my pcv and auto tune kit this morning! hooked it up to the lap top dialed it all in and the bike runs like a beast! i've put 300 hundred miles on it just today! my butt is so soar lol! i do have one question though does anyone know when you set the auto tune for time and temp before it starts, is the temp in Celcius or Fahrenheit? cause that would make a huge difference?
 
nevermind about my previous question, i read the instuctions more in depth and it clearly says Fahrenheit! but does anyone know if i have to configure the engine temperature?
 
From the PCV manual...

"Engine temperature
On Harley models the engine temperature
will be displayed via the J1850 data. Click
enabled and the source of J1850.
For all other models the engine temperature
can be configured thru the analog input. The
more tables that are configured the more
accurate your reading will be. Input the voltage
read at the header pin of the analog
input in relation to engine temperature."


You will need to tap into the signal wire that is connected to the engine temperature sensor. I'm not sure what the calibration scale is yet.

ok well keep me updated cause i would like to use this feature. on a side note it would be nice to have a temp gauge for the bike!
 
Tuning for MPG?

So if I were trying to tune for MPG I assume I would need to figure out the RPM and throttle position at my preferred cruising speed. Then I would pull up the trim charts in the PC-V program and lean out that RPM and throttle position trim. So if that box says -4 it would get changed to -8.

Now if the auto-tune is connected then this is out the window cause it does what it wants anyway and adjusts on the fly.

Is this correct or am I off the wall.


Thanks

Dan
 
Yes, please post pics of your setup when you have a chance. Also, where do you obtain the "LKydex" material? Thanks.

Typo: it's Kydex. A special plastic used to make knife and gun sheaths.

Any plastic will do, just buy a cheap black plastic office trash can a Wally World and cut it up. Probably cheaper. I just happened to have the Kydex on hand.

Will post pictures in a bit.

Here is how I mounted my PC-V & Autotune. The challange is sorting out all the wiring.

I've been telling auto tune to adjust to 13.7 for best mpg when I did the PC V experiments. Possibly the wrong #, but the general idea was to let auto tune go to a afr that would give good mpg.
