maps Yamaha Tmax 500 2009 ABS


Hello everyone,
I finally managed to read and write the ecu of my tmax 500, with the software
Yamaha ecu flasher
Http://hondaflasher.webnode.fi/

ecu tmax 2009_2.JPG


I work mainly with winols to search and modify the different maps.
These are defined and validated.
I now look for the triggering of the cooling fan,
IAP sensor and TPS sensor based.
Probe lambda OFF if possible?
Could you help me ?
thank you in advance.

Regarding the strategy of the ecu, it seems to me to have understood this:
- fuel maps are expressed in terms of the opening time of the injectors,
  
The ECU takes into account the position of the butterfly and the
  
The injection time corresponding to this angle with respect to the engine speed.
  
So I conclude that this map is the desire to injection before correction.
  
- CORRECTION, yes because you have to take into account the inlet pressure and the
Temperature of the air.
  
Therefore the map fuel vs MAP will correct the injection time (enrich or not) with respect to the desired value (fuel map vs TPS) and the oxygen content contained in the exhaust through the lambda sensor.

Hence if the lambda value transmitted to the ECU indicates that the mixture is too rich or lean, the cycle according to a correction will be established (closed loop)
Therefore, if the lambda probe can not be deactivated, will the ECU be based on the injection time requested by the TPS position?

If anyone can confirm that?
