Another PCIII question for 2006 onwards

Hi all,

Just added a PC III in my second season on this bike. Bought a 2006 new in spring 08 and its been a fun bike so far. However, like everyone else, I have found that snatchy throttle requires some real focus and attention. Attention that is much better spent on other elements of riding, throttles should just work predictably - just like brakes.

The PCIII was a great improvement, things are quite smooth now using the canned map 126-003 from the PC site. Now here's my question, the map I am using is close to my bike's setup except that it has staintune exhaust whereas mine are Scorpions. There is a canned map on the site for a European model with the same Scorpions, etc as my bike. Whats the difference with the European maps versus the non Euro maps? Should I use it? Or is there something distinctly different between a Canadian 2006 VFR and a European 2006 VFR? I haven't been able to find an answer to this question in the forums already.

Thanks much for your feedback.

 

I think the European bikes are mapped a little differently. Why don't you download the map and use the Power commanders software to compare the maps? Look under tools and there is a map compare feature, pull up both maps and you'll see what the difference is.

Any aftermarket exhaust should be similar to the staintune map, so the scorpion exhaust's map should be the same except for the compensation for the different euro edition ECU mapping.
We get the euro edition in Oz and the staintune map, although it works Ok is quite rich.
I dont know if you would get the Euro or US version, I would have thought it would be the US version, so you are probably using the correct map.

 

Thanks for the advice. I figured the US map I am using is as good as I am going to get for a canned map on my bike. It does seem to work quite well. Interestingly though while smoothing my powerband nicely, it does take a little power away from starting off the line. This really is a good thing for me since I have dropped a tooth in front and dont need the front wheel coming up too easily anyways.

The Canadian bikes must meet the California level of emissions which I assumed was similar to the Euro standards. Sounds though like the Euro bikes run richer on their base maps if you find the US maps to be overly rich. Running too rich runs the risk of fouled plugs and a burnt out CAT. The map I am running though does not seem to be over the top since I am not smelling unburnt gas in the exhaust, nor am I getting any hesitation or lugging from a too rich mixture. The current North American mentality seems to be the richer the better. However its really about matching the right fuel levels to the available air flow. Too lean or too rich will not achieve best performance.

As a kid I built 60's muscle cars before fuel injected computer controlled systems, one of the first setups tasks with a new or rebuilt carb was to run a lean drop fuel adjustment to optimize the fuel/air mixture. The exercise in that case was to lean out the fuel at idle but under transmission load to the point of just being stable. That in effect was your base of the fuel/air curve.

To be honest, computers and fuel maps make the job of tuning childishly easy compared to those old cars. The only toss up is that you end tracking a lot more electrical faults than one used to ;-).

 

I believe that's a result of the aftermarket exhaust and less backpressure. I noticed the same thing along with reduced engine braking.

 

not sure if you already found the answer or not, but i went to the mfg website and looked it up. kind of along the lines of what dogman said.

"If I live in the United States can I use one of the European maps?

Dynojet offers different maps for the US market and the European market due to the differences in the fuels. In most cases the fuel available in Europe will make a bike run much richer than the fuel available in the US. For this reason we recommend that you use a map that coincides with the region in that you live in. Although we have seen some European maps work well for US bikes so it may be worth trying. "
