Oh how I love to fix it good! Real good.....
You CAN alter the map with your phone if you use a USB cable instead of using bluetooth.
I'm not really interested in altering the maps. More of throttle adjustment fault checks and TPS adjustment is my current situation. But the program/app only is asking for bluetooth connection when I plug in and try to connect to the ECU. Any ideas?
Do you have the bluetooth plug in adapter / transmitter for the bike?
I was trying to get away from buying another piece of gear, but since no solution I have one on the way from Amazon. I was thinking the cable should work, but no....... Actually in the tuneecu instructions the bluetooth is an alternate after the cable. But the app won't recognize it. So bluetooth it is.
Not all Bluetooth OBDii plugs work. I have three different ebay kinds and non of them worked. But they work for my car.
Cable is easy to use and give you more control too. You will need a regular female usb to micro usb cable. It's also known at OTG cable.
I have the cable, it is not recognized. Each time I touch Connect the app starts looking for bluetooth connections.
My bike has gotten a bit herky jerky at low speeds. At first I thought my chain must be getting kinked and I was feeling that, but now I’m wondering if I’m running too lean while shunting along in rush hour traffic.
Can I use Tune ECU to richen up the mixture at idle / low rpms? I bought the cables, but haven’t had the courage to plug it in. I’m shockingly bad with computers considering I use one every day...
The bike has akra exhaust, stock airbox and no canister, if that matters in any way.
Please also me know if you think I’m barking up the wrong tree.
If the bike was running fine in the past with the same map, mufflers, airbox,... I wouldn't touch the map.
Your injectors may not be seeing the fuel pressure they used to see. That translates to less fuel passing through them >> leaner running bike.
If you have access to a fuel pressure tester try that. You should see 51psi +/-2psi. There is a procedure described in the service manual for this.
Dirty fuel filters or as I discovered recently bad pressure regulator oring or a dying fuel pump can result in lower fuel pressure.
Don't mess with the map if it was working fine in the past.
Thanks for your reply — sounds like advice well given and taken.
My fuel filters are about 5k miles old and I’ve been using gurgltech’’s (sp?) pre filters. Maybe this winter I’ll pull it out and replace the pump (as I have with a spare I picked up in the flea market a while back).
I think the PO has loaded the Akrapovik Euro map on it. I just don’t recall it being so jerky previously....maybe I mis-measured and have the chain too tight after repairing a flat.
Maybe throttle cable adjustment? If you do this you must also use tuneecu to reset the stepper motors. There is a section for throttle cable adjustment.
You didn't say what year you have. Tight valves will change the tuning and sync of the throttle bodies. Also, the throttle position sensor needs an adjustment at about 9k miles at the first valve adjust. I've seen the TPS cause a lot of low speed running issues.
I have a 2008. I had a great local dealer — a very small, long-time KTM dealer that seems to be antithetical to all of the horror stories I've heard -- do the valves at the last major service interval. At this time I was also experiencing an erratic / high idle. While we both suspected the TPS, the dealer tracked it down to the stepper motor and replaced that (with a used one he sourced for me!) and adjusted the TPS. The valves were all in spec -- intake @ .125 / exit @ .250 -- and the leak down was 4%.
I have recently done an oil change myself and have put on about 5k total miles since the major service interval. I recall him saying these bikes were pretty stable in that regard...
I bring up the chain / final drive as it does seem kinda rhythmic. And, again, it is only when I'm almost idling along / feathering the clutch in Boston's rush hour traffic. It seems to disappear once throttle is applied, but I guess that could be fueling too.
Appreciate the help and don't mean to derail the thread.
Throttle body sync helps too.
Wow there is a lot of information in here! I have a 07 KTM 990 adv, this bike is new to me and I just spent the last month fixing it from the inside out. It had 40k on the clock when I got it and not much attention had been paid to much other then riding it... Water pump was way past gone (tons of milky goop all throughout the engine) and valves had never been checked... So I tore into it and fixed as much as I could. When putting it back together I installed a Rottweiler intake, SAS and canister removal, and the bike already had dual yoshi pipes. I am currently on what I assume is the stock tune, am I doing any damage running it this way? Would any one happen to have a tune for this set up? Thanks!
There is another thread for the 07-08 models. They have slightly different problems.
Thanks for the info! I will go take a look there :)
If your 02s aren't turned off on the map you should be alright.
TuneECU driver help.
"07 Adventure 60,000 miles
My ancient computer with my TuneECU program which I've used since '09 died .
What drivers do I need to install on my new Dell with Windows 10 ?
I have one of the original cables from CJ .
Also any suggestions on a tune to use ?
As I recall I'm running a tune with '10 fueling tables installed . But the throttle snatch need
to be addressed .
Yes it's been like that for 60,000 miles !
Brains trust help please ......
What would be the consensus of opinion for what map to run with a single sided 2-1 Akra exhaust?
Bike is 2009 Adventure with R mapping currently.
When I got the bike it appeared stock but had the Akra map in it and it ran fine and smooth.
I converted to a single exhaust and its developed bad vibes between 4 and 5k rpm.
Ive checked everything else and reset adaptions, 15 minute idle, TPS, TB synch etc.
Was thinking that maybe Im better off trying the stock R map instead of the Akra?
Is there perhaps a specific map for the 2-1 Akra?
The 2-1 has completely changed the character of the motor, much more bottom end and more linear power which I like but the vibes are annoying.
Thanks in advance
