• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Not telling you what to do, so don't take this the wrong way only suggesting :D. 20% trigger (that's any throttle action from 0-20% open to trigger the added fuel) is too high. 15 revs is only a burst of fuel for less than half a second. So that's kind of like 9% fuel 1 second, but not really because it's over a shorter rpm range. I actually added 14% fuel on Bad's 650 for 1.1 seconds. When you whiskey throttle the 650, it actually takes longer than a second for the engine to fully recover from the sudden in-rush of air. But you wouldn't want to give it that much fuel from 10 or higher % of throttle up. The extra fuel during the 1.1 second burst is like layering a secondary map over top the original one for that instance. Running Autotune while running the accel function is the same as taking an AFR from a FCR carburetor + accel pump, and then trying to adjust the jets on a Lectron to compensate for not having the accel pump hooked up. Is that analogy right or am I off my rocker? I think that's right. :D

If I recall the accell pump values I have are what Dynojet recommended. I started with it and it felt OK so I left it alone. I haven't tried different values for that to be honest. That was kinda a wild analogy but I get what you're trying to say.

I will try your numbers and see how it feels.

I get the issue with the autotune, it's kinda too bad as I like running closed circuit (ie AT enabled).

It appears what's needed is a way to limit the AT's response to quick changes (ie accell pump). Like a setting that anything less than 5-10 seconds is ignored. This way it would not get upset and act more like a smoothing/correction feature.

I think I'm going to try running with the AT disabled for a bit and see how much difference I can notice.

I REALLY wish it was possible to just reprogram the base map tables like I do on my Guzzi, Triumph, and Ducati. That is so much better than mucking about with piggy back solutions. But this is still far better than a simple spoofer.

OK, I really have no idea what I'm doing but have tried to follow Tinker's advice.

If anyone can help that would be great!

My lap top decided to fry itself. I am not able to get a screen shot of my map. I will post one as soon as I can get a laptop.
 
Did some tuning this weekend and without knowing much about how to set the map up myself I went back to the auto tune. AT comes set at AFR of 13.2 across the board so I reset to 13.5 for most if the table except for start /idle range where I set to 12.9.

Bike ran a lot better and didn't seem to be as rich as prior setting. I will save the map it created but will try an AFR of 13.7 next trip out. I suspect I will see improved power from this.
 
Roger, it didn't fluctuate between those AFR's it was just the difference between previous map and the one I posted. Previous map was the stock setup from PC.
I would really like to put this bike on a dyno for tuning but there are none close to me that I know of.
 
I think you can set auto tune to wait for a period of time after starting, before making autotune adjustments. If you can I would set that time to be long enough for the engine to fully warm up. This is important because your ECU has various enrichments for starting, immediately after starting and during warmup.

An idle AFR of 13.5 to 13.8 usually works quite well once the engine is warm.

For the rest of the map I would try 13.5 or 13.8 below half throttle tapering from there to 12.9 at WOT.

You probably don't need a dyno but don't accept large fueling swings from row to row or column to column. For example is you see -15 next to a +18 ask yourself if that seems right.
 
Thanks for the input. I have the auto tune set to 2 minutes and always start up a few minutes for warm up.

From what I understand about it, the trim levels should set themselves after they have been run in at each RPM range based on programed AFR. Correct? So I'm thinking if I just save these each time, at different AFR's I should be able to create the map that works best for me.

Would you say not to go Leaner than 13.8 at up to around the mid range?

From what I have read 14.7 is ideal for maximum performance. Probably not best for a long lasting engine.
 
If you don't like the loss of engine braking with the std PCV map try changing the 0 throttle setting to -100 from 2000 to 8000 RPM, fixed mine.
 
If you have trouble with loss of engine braking set 0 throttle to -100 from 2000 to 8000 RPM, worked for me after talking to Dynojet today.
