Re: Can the ECU be Remapped?

But you know the characteristics of the throttle valve and atmospheric pressure, and rpm, so you can find dM from that.

Pressure sensors are cheaper than MAF sensors too :-P

True...

Am a Honda buff so as far as im concerned , MAF sensors are the work of the Devil.

MAP for proper systems lol :smt023

Re: Can the ECU be Remapped?

Some cars use MF sensors, seems a daftoption to me, some of them are actually wires held in the airflow, so the cooling effect of the air on the wire shows you the velocity.
Others use a spring loaded flapper valve to sense it, which gives you a load of turblent effects which you don't need with high pressure injectors mixing the fuel for you.
Much prefer things with names like weber, CV, side draft etc and nice little components inside you can actually fix if they go wrong.
Bloody environment making my life complicated :p

Re: Can the ECU be Remapped?

Suzuki use:-
Manifold pressure sensor
Atmospheric pressure sensor
Intake temp sensor
Coolant temp sensor
TPS

Maf sensors are for cars and even then on better systems they go to MAP type system.

Re: Can the ECU be Remapped?

it has a sensor for the atmospheric pressure ? , thats pretty cool to be honest.

The only sensors ive got car wise is a MAP , TPS , IAT & ECT. It also had Lambda but since goin turbo weve disabled the computer to read closed loop and opted for permanent open loop for the wideband to work correctly without ECU interference.

The fact Suzukis detecting the Atmospheric pressure aswell as MAP inside the plenum though surely means you could almost drive these bikes anywhere ? , on sea level or even up a mountain

Re: Can the ECU be Remapped?

Pretty much, I think it has both so as to compensate on bikes with SRAD like the TLs

You forgot the Crank Position Sensor as well. ;)

Yes, and with this sensor down stream of the filter it should compensate for the state of the filter as well.

At a guess Suzuki may use the same ECU for all of there bikes that use the two throttle system, but with a map tweaked for each model.
