So I learned a lot about my bike today, I got the seat off (lol), raised the gas tank and found another Power Commander Module, this one is the Auto-Tune which is plugged into the PCV. I found two wires on the Auto-Tune module (which goes to the sensor in the exhaust) that were loose and not making contact with the module. Not sure how that might have impacted my bike but I got them re-attached and fastened down tightly. I also figured out how to use the PowerCommander software on my laptop and was able to connect to the PCV and look at settings (no, I didn't make any changes).
I removed the Bear claw and unfortunately I have a stock intake, with everything the previous owner put into this bike I am surprised he didn't swing for an aftermarket intake. Oh well, I guess that will be one of the mod's I get to do, (after the horn).
Lastly a question, with the PCV and the Autotune on the bike, does running a 12 minute tune (learned that one myself) still apply?
Paul.
Ok what you have here is a good setup minus a decent air intake.
One thing to be aware of is that the 12 minute "tune" is not a tune and dont trust statements where people say "oh you can change the exhaust-intake-whatever and simply do the 12 min tune and it will all be sweet.
The 12min tune is a factory fitment and the bike comes with a narrow band 02 sensor, this only works over a "narrow band" i.e idle and works directly on the bike ECU. In your case it is also irrelevant, here's why.
1. The PVC with AT use a wide band O2 sensor and the narrow band is removed so the bike ECU has no idea whats going on now at idle but this really doesn't matter too much.
2. The AT measures the air fuel ratio (AFR) over most of the rev range now and feeds this measurement to the PCV that intercepts and trims the fuel injection pulses to meet the programmed AFR target in the PVC.
3. The bike ECU still controls all other functions like ignition advance and the basic fuelling, it also adds a big squirt of gas (like a pumper carburetor) when you rap the throttle. So its still very important.
Things you need to do.
a. Get Tune ECU and a cable and hook it up to your bike, make sure the O2 sensor has been unchecked.
b. On Tune ECU open the secondary throttles to 100% would like to think this has been done but with the stock air still on (but Jardines?) I'd be doubtful. You'll also be able to upload a much better base ECU map.
c. Make sure the AT is powered up, should be a light on it with the bike turned on.
d. Download and install the Dynojet Software with the correct cable (a basic micro USB, thankfully).
e. Go into the software and ensure the AT is actually turned on.
f. Upload a blank PCV MAP and have the AT trims on 20%.
g. Ride for a decent time then accept the trims and drop the adjustment down to 10%, you can then go to 5% but DO NOT keep on accepting trims anymore as you will lean the bike out down low due to the "pumper" on the bike ECU, the PCV cannot compensate for this, trust me I didnt learn my lesson immediately.
h. Get an air system
And before you do any uploads/downloads to either the ECU or PCV copy and save whats on there so you can always revert.
You will unleash the real power out of the bike if you do this.
Hope this helps
