Hi! So after this video (Fuel Models) i am a bit lost. My car runs a piggyback ecu "ecu master det3" and i didnt tuned it by my self, but some guy did and when i connected to this det3 ecu to have a look how it is and how tables are filled, i figured that fuel table it self is empty. I mean 0 everywhere, but the VE table is filled, so is this means that that guy didnt filled the fuel table because he filled VE? Is that means that i can leave the fuel table empty and fuel ratio gonna be always ok when VE is filled correctly? Also there is some table filled similar to fueling table but that table is for some input and there is numbers from 55 to 205 or higher, but my engine is 2.0l sraight 6 lesxus is200 and injectors is 400cc. So i thought that the numbers are low on low rpm to get engine running fine with them big injectors, and much higher on top so when the engine is on boost(around 10-12psi) there would be enough fuel and no knocking or misfires he added more fuel... I just dont know for sure... Can anyone help me to understand is this correct setings or the fuel table should be filled but somehow lost the data? The car runs fine tho. Have no issues with it, just very big and slow boosting turbo(TO4E), but that is going to be changed soon to some gt35 ball bearing turbo. :)
Thank You in advance!
I'm not familiar with that particular ECU> Can you elaborate on how the ECU is installed as a piggy back though? Is it modifying the fuel/ignition signals from the factory ECU or is it in complete control of fuel and ignition?
