I am interested in getting a factory ECU that has better mapping than mine. I have a US ECU factory #8H00 H1643

This number is on the bottom of the ECU under the seat. Any body that had dyno run with 50hp from the factory. And it would be nice the find out what ECU number is on the bottom of an ARROW can upgrade.

Try to get an EU TE ECU or the Arrow ECU. But I think I read that you can't order the Arrow ECU without the cans, which makes sense since Husqvarna wants to make some extra money :rolleyes2:

OEM parts

The list of parts for ecu's has 15 different numbers. Ketec did your bike make good power with the stock ecu?

I have ordered the Arrow cans plus ECU from Husky. I'll post the ECU number for this thread.

Ketec, I'm very interested to know what part number is on your ECU. None of the bikes are making those numbers here in the states.

I'm also thinking of buying the Arrow pipes that they list. Part #72092PD

Anyone buy these pipes yet??:headscrat

The parts number at the back of my ECU is 8B00 H1643.

I'd really like to see what the power increase with a different exhaust is. But the only legal aftermarket option in Germany are the Arrows, which are totally overpriced imo. :rolleyes:

They've got higher octane gas at the pump in Europe compared to the USA, yes? Could that be the reason for the different ECUs for each region?

I'm really no expert... I'm just assuming that the timing may be more advanced for regions with higher octane gas...

I recently ordered a USA TE ECU for my SM630. You could just as easily order a European ECU if you were so inclined.

last two pictures



I am going to comment on the right side fit of the very heavy exhaust shields. You guys can see there was not enough adjustment to line this shield up correctly. and the arrow clamp bolt does not allow the right cover to rest against the body work. Poor fit of this right side can. Arrow/Husky should fix this:headscrat

Here are the pics from the ECU that comes with Husky special parts Arrow cans.
So, to clarify....

The ECU that comes with the Arrows is labeled -- "TE630ie E/ 11 All"

The stock ECU that came on your bike is labeled - "SMS630ie R/ 11 USA"


That seems to be another confirmation among many reports that the SMS ECU is somehow less aggressive than the TE ECU.

Anyone care to guess with the "E/" and the "R/" stand for? "Enhanced" and "Restricted" maybe. (Only a wild ass guess....)

Yes, your correct. I also noticed an H.O. on the face label of the arrow ecu. I would guess this stand for high output.
