Duhfacator I did a similar thing, i compared the stock 07 and arkra fuel maps as percents of the stock map. My mpg was shit (under 30) with the arka map, so increase the stock map 1-3% in differnent parts of the fuel map. I left the L maps the same, but I am wondering now if I should be making more changes there, as I think I do more riding at low TPS values, but I haven't marked my grip yet.

In comparing the maps I was suprised to see the +7-13% over stock in some parts, where as most of the table was a +5% increase.

Zubber, to adjust the advance are you doing that in the trim tab?

Did you end up advancing the ignition through that range on your map? Did that improve the "lag" you were experiencing? Thanks for the heads up, I remember reading that now somewhere in the previous posts, but had forgotten it.... Man there's a lot of stuff in these pages to remember.

I'm assuming your running akro's? Did you notice a significant decrease in power going with your modified stock map as opposed to the AKRO map? I haven't checked my milage yet, I'm just trying to get the thing smooth and linear first so I have something to comfortably ride with, then I'm hoping to fine tune from there. I'm trying to leave the F-L switch the same as stock, but making proportinal changes to the L-maps that I do with the F maps. So far, it has become much more smooth, but I'm sure not yet where it could be. I'd almost like to swap maps with you or someone to have a little more objective comparison, knowing that bikes are different of course....

I'm wondering, would you mind sharing your map?

nope don't mind sharing at all, I only have 30 miles on it so I don't know how its doing on the mpg front, power seemed good from the seat of the pants when I got on it a bit. Send me a PM if you what to look at what I am currently running. I have a 2:1 akro wo the insert and stock air box. I have made no changes to the L or I tables, secondaries are at 25% min.

Do you have a "dead spot" around 3500-4000 RPM that you've noticed?

I cannot confirm or deny it at this point not enough miles or time on it, I do remember looking at the tack at low TPS around 3K and thinking it might not be as smooth as it was with the 07 akro map.

Hey Zuber,

I must be an idiot, as I look at the ignition maps from 3500-4000 RPM from 1-10% throttle opening, I'm seeing a spike in the number, which I thought was degrees of advance. In other words, I see an advance right where I think the weak spot is. I'm looking at the stock and akra map from the Tune ECU site, is that what maps your referring to?

Hey PDX, just back from work and bar. I'm looking at the stock map and also the akro map. KTM put in a large Ign advance right at 8% throttle and between 2500-4500 rpm, the worst is the 3500 curve, which is very close to 55 mph in 6th gear. I think this was for emissions.

As you open the throttle, it advances the IGN to 8% throttle - the throttle is overly sensitive.
Then it retards until 15% throttle - the throttle seems dead until you get past this spot.

I've smoothed out some of the 07-08 990's by cutting off this ign peak (retarding) right at 8% and the curves between 2500-4000. It's usually safe to retard. It may help to advance it just above 15% throttle, but don't go very far to be safe.

For an education, compare the ign maps between the stock 09-10 Adv and PowerTrippsWings maps. His are very smooth and work.

What is he using the Torque app on, a car? I searched the web a lot and I haven't read of anyone getting it to work on a 990 yet. Unknown protocol. Power-Tripp discussed it awhile back in this thread, but never did say if it works or not.

Torque connects just fine to the ELM327 and scans and tries all the protocols it has installed and the 990 ECU just won't talk to it, so far.

Yep...his car
I got the same issue, blue tooth connects, but no comms

Ride update......

O.K. folks, seat of the pants update here......

I loaded up the new map to the bike, and had a chance to ride it today, in the freaking freezing cold......

The map I tried this time was the modified AKRO map, leaned everywhere 1% in all fuel maps. I also opened the secondaries 20% from 1450 RPM up, increasing with throttle position and RPM. Also, I increased fuel by 1% from 0-10% TP, and 3500-4500 RPM to try and fix the lag in that RPM.

This map was worse. The lag was still there, but wider in RPM range, and the herky jerky was worse at low RPM. I noticed right away. I tried the tight circles at low RPM in left and right directions, rolling on and off the throttle like I did with the last map (no richening of the 3500 RPM range). This map was more difficult to control the bike, and it was more wild every where. I didn't like it at all.

So, I loaded up the last one I tried, the one where I didn't richen up the 3500-4000 RPM range. It was back to being much smoother, and a great deal better on tight circles, and low throttle control. I know we're not talking about a carbed bike, but if I compared it to carb tuning, I'd say the bike had a bog, as if it's rich between 3500-4200 RPM. I'm trying to decide if I retard the timing like others have done, or try leaning that section just a little to see if it gets better, since adding fuel made it worse. I'm still saving for a wideband and data logger, but no joy yet.

Thoughts anyone?

I followed Zuber's advice and retarded the timing at 8% and slightly bumped timing up at 15% (I also returned my 2nd throttle mapping back to stock). Did the 15min idle let bike cool down and took it for a ride. It was back to the stock jerkiness if not worse. Shut it off for 15min and considered returning the secondary throttles to min 10% but I was too impatient and took it for a ride. This time it ran a lot smoother Thanks for the tip Zuber!! Did you only smooth out the peak at 8% throttle or on either side where necessary?

For those keen to give it a go look at the igntion tables in graphic mode and right click on 8% and you will see the peak betwen 2500-4500rpm

TuneECU and a NOOB

Hey guys I just purchased a 2007 990 Adventure, and it run like a bat outta hell, but (I think) it runs hot- 4 bars on the freeway and the fan kicked on after only 10mins in stop and go 60 degree out. The guy who does the TuneECU in San Rafael re mapped the bike for the prior owner and it's the dyno print out on the front page.

http://www.factorypro.com/prod_pages...dventurer.html

I was wondering if running the bike less lean would be a solution to cool the temp or if this is completely normal operation for the bike. I've done some poking around and seems that people have operating temps all over the board.

To be honest I am really not concerned with peak horsepower or torques just a bike that will run for a long time. Thoughts, advice, tips?
