I would like to use the vtune software, does anyone have any SIMPLE instructions how to do this?

[HOGMIKE]

I have a copy of a "short cut" version that I used years ago, depending on what year your bike is it will still work.
This was for an '09.
I don't know if there is anything for Lambda based bikes.
Hope this helps a bit.

thanks,

I have the manual, this confuses me. i was looking for someones simple step by step procedure.

The only way that document could be made any simpler is for someone who already understands the basic workings of the software and how the ECM works.  If you don't understand both of those, at least to a certain extent, you'll likely not be able to perform a v-tune very well either.

The general idea is to set the ECM to go closed-loop in as much of the operational area as possible so that you can use it to find out what fueling changes it needed to make and incorporate those changes back into the base calibration.

Since we don't have a sensor which measures actual intake air quantity (Mass Air Flow) we need to use "Volumetric Efficiency" tables to model the airflow.  The V-tune process is what's used to get those VE tables set properly.

There are several temporary modes which disable closed-loop operation and you need to either disable them or at least be aware of what they are so you can avoid them while v-tuning.  Because if the ECM goes out of closed-loop operation while gathering v-tune data, it won't gather the desired data during those times because the data-gathering is suspended while the ECM is not closed-loop.

So you see, you really do need to have at least a modest understanding of how the systems work and how to manipulate it if you're going to succeed in v-tuning.

Actually, the same holds true for the wider-range "auto-tune" systems like T-Max and EMS.  If you don't understand the system you'll be relying on pure blind luck, with results obtained accordingly.

To some folks the concepts and procedures are almost second-nature to understand, but not everyone has that ability.  Some have to really study up to be able to come to a sufficient understanding.  And some just won't be able to.  That's the nature of human diversity.  If you can't come to sufficient grips with what you'll need to know/do, your best bet will be visiting a professional tuner, and there's no shame in that.  You'll just have to use your strengths to come up with the coin for it.  And maybe your time is otherwise too valuable anyway to spend the several hours you'll need to do it yourself.
