This is an old revision of the document!
Universally considered to be by far the best modification availalbe is the ECU hack carried out by Samios Motorsports of Athens.
Spiros is an expert and gaining the best of the the engine without overstressing or causeing harm. Personally, I never noted a drop in fuel efficiency either.
Just a few horse power are added to the top of the power curve but a big lump is added to the mid range.
The results are:
- SLightly more power but lots of mid range lessening the need to change gear so much
- Much smoother
- Rev limiter raised to 7750rpm
- Fan comes on at a slighlt cooler setting
- Small amount of fuel added when throttle closes to vastly smooth out deceleration
- No popping as AIS is bypassed (this needs to be sealled or you get exhaust flames)
By using this you bypass the need for snorkel mods or trying to find a power commander setting which works.
You need to tell Spiros the set up of your bike (which filter, which exhaust) and he creates the right ecu hack.
For Euro 220 it is great value.
As mentioned before the AIS needs to be disabled otherwise you get exahaut flames. carry it out as mentioned in the (Link)
