OK let me start by saying that Fuel Moto rocks and I will continue to do business with them as should everyone else. With that said, I had a map loaded from them when I bought my PCV and specifically requested a map for pinging problems. The map that came with my tuner had so many advanced timing tables, it actually made the pinging worse. I had to actually get into the timing tables and retard them as much as 6 degrees in the upper RPM ranges to stop the pinging. The point I'm trying to make is, if you are going to be totally dependent on the map for all your needs without having to do anything but ride your bike, your going to be disappointed. So, you better know how to manipulate the map if it needs tweaking. Fortunately this forum is loaded with helpful threads and members willing to help.

 

Hi,

Buzzard42 please update us when you do the install and run the bike.

With all the discussion about bikes coming "lean" out of factory I would of thought a tuner/or tune would be a good move on a stock bike.

Thanks

I resisted it for almost a year and if Iwould have just bought a PCV right from the start it would have paid for itself a couple times over....for only $300 from Fuel Moto anyone can get into the tables with a laptop to adjust the fields.......

 

Why waste your time with feedback from others? There are 2 maps listed for your setup. Pick one and use your years of experience to tweak it the way you want.

 

Well, I may be the biggest cheapskate on the forum and would not move away from Fuel Moto for $33--not given the experience I've had with them and assistance they've provided over the past 5˝ years. I don't say this in response to the OP or as a criticism, as he's already made his decision, but am offering that opinion only for those who haven't yet made a move toward purchasing a tuner.

To the OP, my experience with DJ maps is that they are quite rich in the cruise range, and leaning them 7-10% by decreasing the values in those areas will improve mileage considerably without much impact on cooling and none on performance. This is based on the maps I've seen, which certainly isn't all they have available, so these observations may not be consistent throughout their library of maps.

I've done quite a bit of "blind" tweaking of PC maps (PCIII and PCV) and the problem you will face is determining where the AFR and VE tables in the ECM are set. It would be a reasonable assumption that the VE tables (AFR) are set close to 14.6 throughout the closed-loop area (cruise range) and 12.5-13.0 in open-loop (roll-on and WOT), so based on this you could get an idea of where the DJ map is positioned and where you need to go. However, it isn't that cut-and-dried, as the ECM programming tends to have AFR's going up and down all over the place. Since stock bikes are set to run at stoich the ECM often shows very rich settings right above the closed-loop area to compensate for the relative leanness and avoid any hesitation. So, if you richen the cruise range that transitional area may not be ideal and will need to be leaned somewhat. Also, WOT is often set too rich at the factory for the same reason and to add some measure of protection for prolonged WOT operation.

You can see the inherent problems with trying to tune a bike without any feedback (i.e. O2 sensors or dyno), mostly because you don't know precisely how your ECM tune is calibrated, and they vary considerably from one year to another. Before investing in Auto-Tune for the PCV I used my senses to determine how far to lean the cruise range, as for my type of riding all canned maps (including Fuel Moto and DJ) are too rich in the cruise range. If I heard detonation I knew I had gone too far and would need to either add more fuel or back off on the timing until it was gone. Any hesitation or excessive heat were other indications, and it helps a lot to have OT and CHT gauges to monitor engine temperatures when doing these blind tweaks with a tuner.

The good thing about a Fuel Moto map is that I know they tend to tune at around 13.8 in the cruise range, and subtracting 5-7% from their standard maps will get you in a better position for mileage without any or much impact on cooling. Their "economy" maps reflect the above changes already. My experience is that running 13.0, 13.5, and 14.5 in the cruise range makes little negative difference in OT, CHT, or throttle response--but quite a bit of positive impact on mileage. Again, this is for my bike and YMMV.

As always, just my long-winded 2˘.

 

I have a friend in a similar situation, has a 2012 sg, was able to get the correct PCV from another friend for $100. He cant afford to get air and pipes right now, but wants to get the PCV installed to help cool it down a bit, and maybe pick up the performance a bit. Does the OP have feedback as to whether the basemap was actually succesfull without tweeking? I was looking at 15-011-057 from Dynojet.
