2017 Rotax ECU Pre-Order

Postby Joey Guyon » Fri Dec 09, 2016 3:36 pm

Hi All,

Rotax has come out with an updated ECU unit for the Evo Ignition for all classes. The new ECU offers easier carburetion in the high RPM ranges, above 13,300. The ECU’s will be available at 50% off until March 31, 2017. The discounted price is $137.47

The Rev-Limiter has also been lowered to 14,800 as there were some ECU units capable of over 15,000 rpm.

I will be testing these items in Arizona in January and will post my findings.

If you have any questions, please contact us or post your comment on these forums!

Just researching this a bit, and this is what I found on the Rotax site:
The ECU with minimized vibration level due to its changed position – used for the Rotax 125 Junior MAX, the Rotax 125 MAX and also for Micro and Mini MAX engines – is less sensitive on the main jet above 13,000 rpm with slightly altered ignition timing. With a richer main jet the engine will perform well above 13,000 rpm. The new ECU is much more forgiving in the set up of the carburetor.

Now the ECU is located on the left side of the battery housing. A multi-function switch is attached to the optimized battery housing which provides an easier handling to the customer.

The new cable harness with plug in connection for the multi-function switch is another feature. The plug in connection for the electric starter incorporates the ground connection for the overall electrical system. The connection for the battery charger is aligned with the cable harness. The support plate system is more compact with electrical connections for the ignition coil and magnet valve only. This results in less complexity and easier handling for the end-user.
This makes it sound like the ECU upgrade includes a new wiring harness & battery box?!?! :?
However, another Rotax site indicated that it's just an ECU exchange, and that there is no program to update the harness and the box, so if the ECU is going back in it's original location, where it is still subjected to the vibration issue.
I am definitely confused...

Hi Steve,

Good question. Not too clear from the various documents, but the wiring harness and battery box is not included with the ECU. It is optional and may be used in conjunction with it.

From a phone call with the Rotax Techs, it seems that the issue with the ECU vibration is damage to the wiring harness. I am told it's function is not phased by the vibration.

The new wiring harness and ECU location should increase reliability, but is not included in this upgrade program.

Please post any other questions,

Joey

Thanks Joey!

So is this an outright purchase for the new ECU at $137.47, or is it an exchange?
If I can keep the old one as a spare, it makes sense.
I await to hear your verdict from Arizona.

Hi Steve,

It's an outright purchase, no exchange requested on your old one!

Regards,
