KTM SMT 990 Ecu Tuning

This great example of a well maintained KTM SMT 990 was dropped to me by a motorcyclist who has a love for KTM and had some heavy modifications carried out.
Ktm 990 SMT
The bike had an aftermarket fuel controller fitted and the customer wanted to removed the controller and work of the bikes ecu only ( no chance of a fuel controller fail).

The Problem:

The bike had a generic flash flashed to the ecu previously to suit the modifications

Akrapovic end cans , ITG Megaflow air filter custom velocity stacks and Secondary butterfly’s removed.

The customer complained of the bike running rough lumpy not smooth and not linear since the generic flash .I aimed to improve theses issues when the bike was with us to improve on fuel economy and to remove the dreaded KTM snatchy throttle.


airbox removed

What was done :

The bike was a joy to work on as it was so well kept. Firstly I took a read of the bikes ECU. The bike was then put onto the dyno and a base reading was taken before any editing took place. When on the on the dyno I could see and feel the problems that the customer had described to me and seen that the bike was over fueling nearly everywhere.

Firstly a sweep test was carried out at 100% throttle

Some custom ignition editing and fuel editing were carried out with the first flash to the ecu and gains were made using the generic flash as a base to work from.  After some multiple edits with the generic flash we couldn’t progress anymore and no more power could be achieved and the bike still had some issues. I reverted back to a standard SMT 990 flash and began customizing  again . Few hours later the results below are shown (pretty impressive) the sharpest SMT I have ever rode .

Results :

Generic Flash Red


Custom Dyno Flash Blue

Option 2 : Get your ECU flashed to pre configured on dyno flashes to suit your bikes configuration whether it be a full exhaust system , slip on end can or high flow air filter etc   Price: €350
Option 3 : Bring your bike for a custom ECU flash – this is what we did with Pjs bike. Dyno print outs before and after and your bike fully customised for optimum performance / efficiency . Price:€450
Option 4 : Bring your bike for a custom ECU flash inc Air box removal base plate and filter supplied secondary butterfly’s removed and velocity stacks with print out before and after . CALL!!!!

Customer Testimonial :

The difference in the bike is night and day, its a joy to ride now.
What really blew me away was how bad it was vs what it now.The benefits were:
1, Cured my starting issue.
2, Fixed the ignition timing
3. Improved torque and hp
4. Massive improvement in ridablity
5. Better MPG
6. Smoother Idle
7. Reduction in vibration at cruising speeds( this was a serious gripe for me)After my experience I would suggest that every bike be mapped, I would highly recommend Gary at Mototuning. I am very impressed.
