Hello Husky's riders

I have on my Husky the stage 1 and 2 air filters from DNA, I did the black chamber delete and I have Merkes exhaust (not yet removed the CAT but it could be an option). I have the Fuelx Lite, but I was wondering if it was enough and what was the difference between this and the COOBER ECU ?

Thanks.
 
Fuelx lite is not an ECU. It’s only a lambda sensor fooler. The Fuelx Lite only works its magic when the lambda sensor is activate, meaning low revs and/or low throttle input.

For “optimal” gas mixture all across the rev spectrum you’ll need an ECU. There’s also an ECU available from Powertronics that makes the FuelX. Riding the bike with a free flowing exhaust system might damage the engine due to the mixture being too lean, so I would highly recommend installing an ECU if you are doing a cat delete.
 
Ok, thanks for your answer

I have the FuelX Lite and I have, 2 filters, and chamber delete but I still have the CAT, with this configuration the fuelx lite is not enough?

can fuelx lite and the powertronics ECU be combined or is the ECU alone sufficient and fuelx lite disconnected?

The powertronic ECU is worth the quality of COOBER?

Thanks
 
There are a lot of options and even more opinions; nobody can answer you surely except a dyno test or maybe some tuner who has spent a lot of time tuning 401 bikes and has tested all of the things configured like you have / want on a dyno on someone elses 401 bikes.

How does your bike run?

Generally: As long as you have the cat and not a complete open exhaust system, you are not opening up the system enough to “have to have” an ECU. But of course an ECU would be better than the stock ECU.

I have no idea which one is better of the two. I don’t worry about the cost, I just can’t bring myself to going through the install process.
 
Thanks,

I share with all of us the responso of Powertronics tu my questions :

"Hello

Thanks for contacting PowerTRONIC

PowerTRONIC improves the performance and FuelX is into refinement.

For a perfect balance between performance and refinement you can install both PowerTRONIC and Fuelx".

My bike run very well like that since 1 month, but I'm worry about to damage the motor o something like that. That's why I was thinking about the ECU, I was not looking for more performance with the ECU only for more security for mi motor. But I think that it's can be only if a do the deCAT like @yonsson said
