flipped the key off, then on, the TPS 0,85v remained unchanged even after connecting tuneecu again. Started the engine and imediatly the revs went to 4k rpm and stood there for a while, then dropped to 3,5k and stood there.

Turned the engine off, loaded the previous map, did reset adaptation, TPS voltage went down to 0,68v. flipped key off, then on, started and it idled fine.



WTF? the tps voltage looks rather high but below that after many many tests, it kept the revs high without dropping below 3k.
sounds like the speed idle motor setting in that other mapping is different?. just compair the idle speed setting.

by the way a tps voltage of 0.68v is quite high, this should be between 0,55-0.65v when the engine is warm (according 2011 ktm smt/smr manual) so optimal setting is 0.6v when the engine is warm

If you're talking about the map idle settings, these are the same. Even if they were different that would not cause this high idle.. afaik.

Yes, the tps voltage is quite high but it's the only setting where the idling works ok. Tried many values, believe me, many values, from 0,45 up to 0,8 , this is the best it could do. On my 950 had it set to 0,6 flat and it ran like a dream. this one is acting like a bitch...

did you ever reset adaptation after readjusting the tps? sound like your doing manual adaptation with the tps instead of calibrating the ecu software to the new setting.

strange...

just a long shot, because i know the ecu also uses the map sensors for idle rpm.
and i assume the throttle bodies are properly synched.
maybe there is a rubber booth between the throttle bodies and cylinder a very little bit leaking or the map sensor connection is a bit clogged (at throttle body).
causing this strange behavior??

Not sure if i understood you correctly, you mean press reset adaptation after every tps (device) adjustment? For sure i haven't done it always, but after any map change i press reset adaptation... just in case.

Am i missing some step?

Can't be 100% sure, only if something microscopic but i've removed the TB's to check the intake boots, and all piping related to MAP sensors. Both have been thoroughly blow with compressed air.. no signs of any kind of blockage.

Yes TB's appear to be synched, relying on tuneecu map info, these are less than 5 units apart from each other.

Thanks for all your help

Hi there,

did you by any chance check the condition of the fuel filters? Had something similar a couple of years ago (and EXACTLY the same now) and it was fixed by new filters. I haven't had the opportunity to install the new filters yet (KTM didn't have any on stock, ordered them in August... finally got them in November - a bit late to mount / test them) but I'm hoping it would fix it again.

I've got a TuneEcu cable on it's way anyway.

Thanks, Alex

Values in F1 and F2 tables

Ok so have been comparing differnt maps, stock, arka, custom extra and know I am wonder what the values in the fuel tables actually are, or put another way what are the units for the various tables?
Thanks

Milligrams of air. Higher the number the more air the ECU thinks it is getting. The more fuel then the ECU delivers.

Did you use a battery charger when you did your work with tuneecu? Its draining the battery, and when the ecu reads battery power under a defined point under its start up check, it responding with higher idle rpm,s typically about 4000 rpm.

Yes.

But when loading back the previous map, did not use the battery charger and when started the engine the idle was fine, so we can assume the battery had good power.

Anyone need a Cable?

I've got a spare TuneECU cable for the 990Adventure. If anyone is interested send me a private message.

Adjusting the TPS and High Idle

When you adjust the TPS, the idle may be very high or low afterward. You need to turn off the power for 5 sec. or so to let the ECU clear out the previous setting. Then when you re-start it will be normal again.

If you get erratic idling. Look at the TPS sensor quality. Open the throttle and snap it shut, it needs to go back to the same voltage. It should smoothly change voltages when you move the throttle. These will get dirty and need to be replaced.

Did that too. Waited far more than 10 secs. Same results.

Doesn't appear to have erratic figures, did that too. Even did the adjust throttle procedure of the 690, power on, rotate gently till full, then back, switch off, always looking at the voltage value and % pointer in tuneecu... One interesting detail is that at full throttle the voltage is 4,07volts instead o 3,91v or so... been told to ignore this, but it seems rather unusual.

I've had a bad load with TuneECU before. Very un-ballanced running, poor mileage. Loading a different map and then the desired one again fixed it.

When you load a map, TuneECU will perform a Reset Adaptation for you. You don't have to push the button again.

You can ignore the high voltage at full throttle, all TPS' are different.

So, does it run ok now?

I've been trying out different maps and settings and improving the feel of my bike. Now i think that i should go to a FI tuner who can tune the bike on a dyno alongwith AFR measurements. My intention is to have smooth power and better mileage. Not looking for peak power, but will be happy if it is a side-effect

oh, and a BIG thanks again to the TuneECU creators, just made a small contribution for their good work and suggest you guys (who still haven't done so) to consider doing the same.
