Thanks,

I get 40 tops with that combo and nobs.

I loaded the standard map, switched off the ignition, switched the ignition back on and done a full rotation of the throttle, switched off ignition again and then performed the 15min idle.

I need some help if possible.
I'm not sure where you got the idea to twist the throttle after switching on the ignition...
Do not touch the throttle until the tach completes its sweep...then start normally...

The throttle wasn't touched until after the sweep. After loading the aka map and doing the 15min I took the bike out, I wasn't 20 seconds down the road when the throttle went crazy staying up about 5k .

Sorry dude.

One quick easy thing to try is to turn off the O2 sensors and do another test.

Steve
I thought the O2 sensors were off if you are running the Akra map.

That's not always the case. With TuneEcu you can turn them on and off independently from the map you choose; I've seen akro maps both ways.

IN any case, if the nosedive in mileage was associated with mechanical changes, I think it's wise to double check those before going further with mapping. You're on the right track.

Air leak from the SAS removal, ECU compensates by dumping in more fuel = poor fuel mileage and gas smell

I think Viola-tor said the situation continued after loading a stock Akra (O2 sensors off supposedly, so ECU couldn't compensate) lending further credibility to some issue with canister or SAS removal.

Done the whole lot again and took the bike out ror a run. She starts off fine idling at 1750 but once the revs get up they won't come down sitting at 6,000 in all of the gears. Pulling in the clutch makes no difference. I had to ride with the front brake.
How do I get this sorted ?

Another success(es): I've saved the stock map (the one that was on there anyway, I assume the orig), and have loaded the KM601AK0704501 '07/'08 Akro slip on/US spec map onto the ECU. Bravo for me! The voltage again dropped to 12.2 as I sat there, but then held steady there with tender connected.

I exited the program, disconnected, and the bike fired up just fine, but I didn't run it long or go for a ride to test yet. Maye tomorrow. I also ran all the tests that were available in the Testing area, it was cool to hear the bike clicking and whirring without me touching it! It looks like everything passed (I'm assuming it would tell me if it didn't?).

My main concern at this point is MPG. After removing canni/SAS I'm getting confirmed 23mpg (down from mid 30's, which still wasn't great IMO) and I smell gas all the time. The bike feels fine, plenty of normal power and zoom, but having the reserve light on at 86 miles simply will not do. DirtJack's '07 990 down the road gets 40+ mpg, also with canni/SAS removed, so something is def out of place.

Thoughts? I've heard the Akro maps can make mpg even worse... I guess a test will tell!
Re-reading your post, I don't see you mention that you did the 15 minute idle or the throttle grip calibration after loading the Akra map.

I most certainly did do 15 min idle.

Grip calib? No, didn't do that... What's the "official" procedure for that for the LC8? On my BMW it was turn on ignition (don't start bike), and then move throttle from full closed to full open to full closed, twice, then turn off ignition.

Did you do the 15min with a cold engine and without touching the throttle?, because i readed last week on a dutch forum. somebody with a superduke who was suffering with the same problems.But he finally got it solved with a proper 15min idle

it's the same procedure but just one thottle action from full closed to full open to full closed.

Before 15 min idle?

According to the TuneEcu guys, there is no "throttle calibration" for the 990 ECU, only the 15 min reset.

Steve

"Reset - Keihin ECU - only KTM

After downloading a FI-map, start the engine and let runnig it idle (without touching accelerator) for 15 minutes,
then turn it off.

After downloading a EP-map, Following a mapping download into the ECU, turn off the ignition (key) , turn on the ignition, slowly rotate the Throttle until full throttle then slowly close the throttle, turn off the ignition."
For the KTM 690 both cards are always required (FI and EP-Map)
FI is a acronym for EFI = Electronic Fuel Injection
EP is a acronym for EPT = Electronic Power Throttle"

From superduke net:

Have a look at this it might explain it !! for KTM 690. I think the EP map is more to do with bikes with fly by wire.

About 690 EFI mappings
KTM 690 models all have the same Keihin EFI system. This EFI system is different in a number of ways than on most - if not all - other bikes. It uses a 46mm single valve throttle body with two ECUs. One controling the fueling & ignition and the other controling the throttle valve through semi ride-by-wire. The ECUs interact with each other communicating over a CAN-BUS connection (CAN-H & CAN-L in the drawing). The two cables from the throttle grip hook up to the throttle valve but the ECU has the ability to 'take over' if needed. Closing the throttle valve is 'hard wired' for safety reasons. Under normal conditions the throttle valve will follow the commands from the rider 1:1. But if the throttle commands get outside the working parameters of the engine, the ECU will take over controlling the throttle valve in a way that the engine will keep performing optimal. For instance; wacking the throttle wide open in a split second at 2500 RPM in 5th gear will normally stall the engine. This is when the throttle ECU takes over and opens the throttle as quickly as the engine will allow without stalling. A neat and sophisticated system that works really well. The fact that you never feel the ECU taking over when riding a 690 kinda shows how good it works.

Because of the setup with two ECUs the 'mapping' or 'fuel map' for a 690 also consists of two parts/files. A map (file) for the fueling: ....FI.BLZ and a file for the throttle: ....EP.BLZ. This has led to problems and confusion with both dealers and owners. The two parts of a fuel map belong together and are NOT interchangeable with other fuel maps. When updating or changing the fuel map it is critical that both files are downloaded to the bikes' ECUs.

===




There is no "EP" map on the 990, therefore, no throttle calibration is required.

True but the throttle calibration is a reset for the ISC which I think is worth checking in his situation. But you are correct that it has nothing to do with a map upload.

Idle speed control? Got docs on how the reset works? Is this different than doing the throtle cable adjustment?

Is the reset independent of TuneEcu? That'd explain why I'm clueless...

You're talking to the fella with the high idle, not viola-tor with the poor mpg, right? We've got two issues running together here...
