PostSubject: Beetle map and minor tweak   Sat Sep 09, 2017 6:09 am

Hi All,

just thought I'd report the successfull installation of the latest map from Beetle's collection. Was really simple thanks to his great howto. Everything still seems to work so far, but I still have to find the time to take her out on a tour to compare. Anyway, while I was at it, waiting for the lenghty read, I somehow got the stupid idea to start polishing my bike and even gave the exhaust manifold (weird word) a decent rub with some 1000 grit sandpaper to finally get rid of the burnt in rubber from years ago. Looks good so far. After a bit of polishing they went all shiny again and hopefully will stay that way for a while. I also gave the tail section a little work over. The plate holder has been changed to something more badass and I cut a bit off the plastic stuff which used to hold the licence plate before. Currently I am waiting for my Dart classic screen, which is on the way, and looking at options for new indicators and mirrors to match the rest of the bike. Suggestions welcome Very Happy

While I mostly read and enjoy your conversations here I'd like to say that you have been of great value with inspiration and help for my beginner modding ventures so far. Thanks for that and you all go to hell for making me spend a fortune for stuff that no one really needs and most of my friends don't even know what it is! With that said, let the pictures speak for themselves. Hope you like what I did so far. Feedback is welcome of course (unless it is critical that is  Cool )

Tail tidy also looks awesome. The solution how to illiminate the number plate is great, maximum respect!

Thank you 2highlander. Actually, the nice result of the tail operation really surprised me. I got a replacement tail from ebay before just to be on the safe side. Maybe I will go at it some more with a file and some sandpaper to optimize, but that would be just for my perfectionism. The good thing about this solution is that everything else can stay as is. The light for the licence plate should be ok I guess, otherwise I'll just try to switch to a stronger bulb maybe. In Germany its a must have for the technical check, so I don't want to get into any stupid discussions there. I had to lower the licence plate a few centimeters though to account for the dip of the wheel under heavier loads, but now it should be fine.

The saddle is indeed a looker and together with the belly pan the nicest change by far. Got that idea from this forum btw. And it was certainly worth waiting for it to be manufactured and shipped. My wife and I were sitting on the balcony in our vacation in italy going through about a gazillion color options in the config tool Very Happy To be honest, we may have had a beer or two Very Happy Bold choice but definitely a good one.

After a couple rides with the new map I have to say that it makes a notable difference. Maybe its just wishful thinking, but it seems even the gas mileage went up. Is that possible? Anyway, regarding torque it seems to be better distributed along the rpm range. But hey I am not expert and this is very subjective I guess. Also it seems that I get way less popping when going downhill. So even if I should imagine things only, I am pleased with the result Very Happy and that's what this is all about, right?

It's not wishful thinking.

Yes, once you understand how the W5AM works in closed loop.

Yes, although the reason you get no popping on the over-run above 2,700 rpm is simple. On a closed throttle there is no fuel delivery above that point. No fuel? Nothing to make 'Pops'. Simple! Very Happy

Hmm not sure about your last statement. Usually when I went downhill e.g. passing that beautiful castle you see in the photo, she made a hell of a lot of noise. It was so much that I switched to iridium spark plugs to sound less like some moron on a broken bike Very Happy

Sorry, I wasn't clear. That is one of the differences in Mark's OL map. It chops the fuel at 4.8-5.2, (I think.) above 2,700. The factory maps continue delivering fuel in that area but because the engine is pumping harder the mixture is incombustible in the combustion chamber but when pumped into the exhaust it is ignited when the engine 8, 12 or 16 strokes and expell hot gas into the headers and silencing system.

Is that the negative throttle movement parameter when viewing the map in TunerPro?

4.8 is the 'Fully closed' parameter on the 8V, 4.6 on the 2V. I presume that the higher value cut off is designed to take into account bumps and 'Wrist twitch' on the throttle. Hopefully Mark wil confirm.

As I understand Marc, throttle negative movement is able to shorten the duration of fuel injection time. As a result, fewer or no fuel is supplied when you draw back or close throttle.

Less fuel, but not zero fuel. Below 6% throttle at RPM > 2750, fuel is cut to zero.
