Help needed PCV and Auto tune

[MrT]

I have a 2008 R1200 GS fitted with a PCV and auto tune.
Started with zero maps, after riding the trim is still at zero.
I have checked the box in the setting for auto tune and not checked the box for switch.
I have tried 3 or 4 times after riding with no success.
Any help???
Thanks

Call me crazy, or ignorant, but what the heck is he talking about?

PCV is the Power Commander V. Read about it at Power Commander V, Power Comander 5, Powercommander

Except if you click on the versions for a 2008 model it takes you to a page about the Power Commander III. Does the V run on an '08?

Autotune is an optional bit described here: Auto Tune Kit, Autotune, Power Commander AutoTune

Now you know as much as I know which is still not enough to answer the original question.

[MrT]

People who need it explaining,will not be able to answer the question.

I made my post short,because people who know about this don't need an explanation.

Power commander V can be fitted to a 2008 bike,only thing is the maps are made for 2009 or newer.
I spoke with Dynojet and they confirmed this.
If fitting an auto tune,this does not matter about the maps, the auto tune tunes the bike as you ride.
After a ride you can connect to a laptop and download a table of (Trims) alterations that the auto tune thinks is better than what are loaded to the power commander.
It is recommended to do at least 300km before accepting the (Trims)alterations,so the auto tune can build a good map.

So what I am saying is that after riding my bike and downloading the table to my laptop, the (Trims) alteration are still all showing zeros.
Unless my bike is tuned perfectly from the BMW factory this should show some sort of alteration is needed to the map.

I hope all this makes sense.

Have you changed anything on the induction or exhaust? If not, then it may be that there's no signficant difference between the OEM map and what the PCV is recommending. I can see the point in fitting a Power Commander if, for example, you've fitted a full exhaust system without cat' or a free flowing air filter but other than that....

[MrT]

I've fitted an akrapovic exhaust.
Friends and People who have fitted them,say it's not a matter of more Horses,
it picks up better in mid range and runs smoother.
I will post my thoughts,if I ever get it working properly.

Do you mean a full system or just an Akrapovic {say....Ah-Crapoh-Vitch} end can? A full system will certainly mean that the OEM full map will be too lean in places.

Just the end can

Here is a screen shot of the trims after a 330 km ride.
Does anyone know if +20 is to much?
Most trims are +4 -4 at most apart from at 2%throttle 1500-4500
after accepting the trim,this then puts the fuel map up to between 34 - 41 at 2% throttle
Thanks for any help

The +20 trim value is the maximum allowed figure by default autotune setting. By having this full +20 in some cells, it is very likely that the autotune actually wants to add more than +20, but we don't know yet by how much.
My suggestion is to get more mileage after you accepted the first trim table you got. If you get rows of +20 again in 2% throttle, it will be too much and it's better not to accept the trim table again.
I had experiences of autotune overcorrecting the low rpm 2% throttle range on Harley Davidson and GSXR. The owner of the bikes frequently check and accept the trim table then problem starts to appear. In 2nd or 3rd gear, chop the throttle for a few seconds while slowing down, open the throttle again and the engine will hesitate to pick up.
What I did to solve the problem are :
- reset the PC V fuel table to original state (use either zero map or map supplied by power commander for your particular bike)
- clear the trim table
- make sure all rows in 2% throttle columns of AFR table are set to 0. Autotune won't create any trim value if the related cell in AFR table is set to 0.
Let the fuelling of this low rpm small throttle opening area at the bike's factory setting. It will be ok as you only change the end can.
