Tweaked Map for Clutch Switch Mod

[protondecay123]

I interacted some with Dynojet at the Sturgis Rally and tweaked the map some. I will try to post a text file of the AFR's.

On the AFR document the Columns are Percentage of Throttle

0 2 5 10 15 20 40 60 80 and 100

The Rows are RPM's starting at 500 and going to 8500 RPM's in 250 rpm increments

500
750
1000
1250
1500
1750
2000
2250
2500, etc. all the way to 8500 for the Super Ten.

You will notice zero's along the lower rpms and throttle position on the AFR table and in the fuel map as well. I've zeroed these because with the clutch switch mod the bottom end is strong and theres really no need for significant increased AFR at those levels IMHO! I double block the Autotune with zero's on the fuel map and on the AFR tables so to keep idle and cruising range at stock levels for MPG. Jaxon actually taught me the cruising part with the map he initially installed on the PCV and it makes sense to squeeze fuel economy out in that style riding.
Also you will notice that my range for fuel adjustment is relatively restricted at 10. This keeps you from getting "too much, too fast" if you know what I mean.

Also I changed the time for Autotune to start to the 300 second mark rather than the 60 second. My map got tuned to really rich conditions because for a couple of weeks I only did a 7 to 10 minute commute to work. When I headed out to Sturgis, the motor got really hot and was too rich at idle.

So I went to Dynajet's trailer on Lazelle in the heart of the Beast and Dan there hooked me up, tweaked a few things and went from there FREE OF CHARGE!!. After the redo of the map the Dynojet people recommend riding the bike for at least 30 minutes solid. I took the bike for a ride the next day from Custer via Newcastle, Sundance and Hulett, WY via Belle Fouche back to Sturgis. Dan hooked me up again and everything of course was fine.

The AFR's were quite high according to the Dynojet people, but this bike loves them. I got 121.2 miles on 2.977 gallons ~ 40.7 mpg with this map and AFR's and it's a fun ride!

Sweet man - I'm gonna run this for a few days before my trip down to the Eureka Springs area on the 23rd and see how the fuel mileage/power feels. Took her for a few mile jog tonight with no ill effects, smoooooth as always.

My hat's off to you guys for having the patience and perseverance to tinker with this kind of stuff. Impatient dummies like me just get on the stock bike and ride. ::26::

I do find all the write ups interesting, I'm just not brave enough to tinker with my baby. ::022::

 

[Karson]

I get what you're saying completely. After owning a KLR and needing to take the tank off for almost everything i did to it, it's comes as a nice surprise to work on this. I wouldn't do anything unless I was 100% confident or had prior communications on this board with folks before posi-tapping into wires

I also agree. There are enough people on this board that, even if you do screw up, you will be bailed out. Some of these people are pretty freaking good.. ::021::

Proton.......

I really like your idea on bumping it to 300 sec. I bet the ECM is running a 'warm up map' (all the time before the bike is up to temp)and the Auto Tune is trying to counter that before the bike is 100% up to temp after the standard 60sec laps. It might cause some strange trim numbers. I just made a few small changes to my map and also changed the 300 sec lead time for AT. Looking forward to seeing the differences...

Ahh good catch - I overlooked that AT startup delta comment in the first post. Guess I'm hooking up the laptop tonight

Ugh, all spanish to me! HAHA, I can turn a wrench but diagnostics on electronics really confuses me. I'm planning on doing some of these mods after the first of the year. I'm going to have to buckle down and figure it out.

What engine temps are you seeing cruising around town? Averaging 25-35MPH on a 75 degree day, I couldn't get her to drop below 205. Not that it's bad or anything, I just haven't noticed the engine temps that high, especially since this is probably the leanest map I've run to date.

75* day ? I can answer that in about 2-3 months.... its been 105-109* F here everyday.... 35Mph mine is about 205-210.. if I I go much faster it drops to 180 ish.

Hey I just went out and checked everything and the trims looked really good on that map. I'm going to play some with the geometry of the AFR's. The map is smooth on the throttle with the AFR's as is, but I was thinking of how I could make it smoother and keep my MPG.
I have surrounded the "closed loop" with an AFR of 13.4. This seems to work well with the fuel I'm running now which is 91 octane , no Ethanol. The AFR table has No greater transition up or down, right or left of greater or less than 0.2 ( i.e. 13.2 is bordered by 13.2, 13 or 13.4) Also there are 32 RPM ranges ( 500 to 8500 in 250 RPM increments). The highest AFR I'm running is 13. 4 and the lowest is 12.6, so at 0.2 increments this is 5 to 6 RPM rows.
Obviously at 2% or 5% throttle there's not much reason for a 12.6 AFR, so I may cap those at high RPM's to 13 or so. Once I run this next map I'll post up the AFR's after I see how it runs.
Gonna keep the fuel map at 10. :question:

 

[Karson]

man, james! i'm impressed now. i tinker here and there based on how it feels at various RPM ranges, but never think ahead as to how i ride at various throttle %'s and base my AFR's on that. only in the low RPM, low throttle did I do that. my hat's off to you man...if we get the chance to meet up week after next, i owe you a beer. ::003::

 

[protondecay123]

Well Jaxon and I talked some about the maps and it was his idea for the zeros during cruising. Dan the Dynojet guy told me that cruising is usually 12 - 18% throttle, which goes well with 10 to 20 range on the Columns in the AFR table.
With the clutch mod I don't need any help really from 2 to 10 % at low RPM's because of the jumper.

Hook up the Computer and look at your RPM's per throttle position.
In 6th gear at 2K RPM's the speedo shows 40 MPH (city street cruising) , at 3K RPM's the speedo shows 60 MPH ( highway cruising) and at 4K RPM's the speedo shows 80 MPH ( interstate cruising), so there is your throttle range for cruising.

My thought is why burn a lot of extra fuel when you are idling or cruising?
The 13.4 AFR seems to provide a decent transition between stock AFR and good acceleration to me.

And I know this may seem like heresy but with these AFR's it seems to me that you can run regular gas with no problem.YMMV

 

[~TABASCO~]

James,
I agree.. That sound good.. When I worked on that map the clutch jumper had not yet been discovered. And for sure that map was on the richer side of things. Ive been fine tuning my current map adjusting certain cells and leaning out in .2% increments. Ive gotten the slight buzz out of certain RPM windows and the bike seams to just feel better and better with these incremental changes...
Thanks for the heads up on the longer AT wait time.. Makes a lot more sense in the grand scheme....

 

[protondecay123]

Hey Jaxon, thank you for introducing me to all this and helping me out. I've just been playing around with some ideas. I've only run these AFR's today but did take a "spirited" run down 540 for a while. The AFRs surrounding the zeros in the 0% throttle position, idle range and cruising range are still 13.4 mostly. I've played with making the transitions only 0.1 rather than point two. As smooth as that last map was this one is smoother. NO change to the fuel map. I haven't checked the trims but from the way this is running and sounding ( a few pops on decleration) I think it will be a goodun.

I have the flash so it definitely different. I get to play with the now open loop area and it seems that the flash wants more fuel. Crazy thing is my bike was working GREAT last weekend and my dash said I was averaging 47 mpg and some change for the day.... I have found in this heat I had a bit to much fuel in a few cells and I have backed them out too 13.2 (I had 12.9 / 13.0) That took the vibe out and made the throttle more sharp. With the Auto Tune it sure is nice to see some real improvements, then come back and look at the results and really fine tune it. What are you seeing with you trim tables? What type of numbers? Maybe snap a shot with your cell phone and text it to me..... Whats your average fuel economy off the dash ? Make sure to zero it out before getting a new reading.

 

[protondecay123]

I've been running those latest AFR's for two days now and really like the map. My trims were all NEGATIVE! And grouped around the Zero's in the Cruising Range. None of those crazy double digit numbers either. Everything was in single digits. I think that that is telling me this map is pretty close to home for my bike. No MPG yet, but I don't think that is going to be greatly different than before, though we will see. ::026::

I had some popping on decel, just a little bit in the mid-RPM range, so I looked at my trim values last night after a hundred mile ride riding all throughout the RPM range. Mine were all single number negative values, too. i think given our altitude, mods, and fuel, this map is pretty spot on.

I think that the PCV screws with the onboard MPG calculator some how. At one point it read 51 mpg and when I filled up it was 40.5? WTF? I'm doing the MPG by hand at the pump these days to get it right.
The last fillup with the 0.1 transitions I averaged 36.7mpg but was doing Interstate at 80 mph. I'm back to my regular commute this week and will see how that goes.

Jaxon, I just texted you my Trims and AFR's. I'll post them here as well.
