The ECU cant adjust that far outside its zone. Since the stock mapping on the MTS1200 10-12 is abit on the lean side to begin with, it´s going to run ever leaner with this mod inplace. Not dangerously so, especially on a road bike that doesn´t go WOT all the time like a trackbike. But not getting the full benefit either.The ECU will adjust since it isnt going to drastically affect any of its maps. Its going to run the same as before with the exception of a little induction noise
There WILL be improvement from the mod regardless of the mapping being done. Most of the improvement comes from cutting the left/clutchhandle side of the airbox open, not the snorkle cut right/throttle side off.Thank you Carlo,
So is there any added benefit for that mod without the mapping?
I'm just thinking, sense it's so easy to do at home while the bike is open now...
But the mod deos create maximum power and torque gains if you combine the opening with an adjustment of the fueling to fit.
If you have the termi system with Termi ECU, the bike does get abit more fuel where it needs it on the map.
See here. (Bear in mind that the torque is in Nm, not ft/lbs)
Green is fully stock. No mapping and no mods. 140.99hp and 116.5 Nm max torque (85.9 ft/lbs)
Red is mapped. max power increases by 0.5 hp and 0,6 NM (0.4 ft/lbs) gain. usually doesnt do much to map a stock engine nowadays.Blue is the result of cutting the airbox open and slightly adjusting the map. Gains jump with 3hp and 3,8NM(2.2 Ft/lbs)
BUT!! Thats not the whole story. Look at the crosssection at 5000RPM. Where you ride everyday. No one spends time at 10.000rpm on a MTS on the street. But at the 5000 rpm sweetspot, suddenly power is up by 4,5 hp and 6,5 nm (4,4ft/lbs). You have the same power/torque availble at 500 - 1000rpm lower Engine speeds compared to before. That is a huge diffrence. especially in higher gears like 6:th. You can cruise and ride at a higher gear then you could before. You have more power on tap at any givven RPM. And its free.
What does all that translate to? Well.. With a nice 15/42 gearing, if you roll on WOT at 3500rpm, the front comes up slowly at 7500 rpm or so and its a piece of cake to float it to the redline. You start handing "power cruisers" their ass at the redlight and sportbike riders dont like you anymore.
