Afr's as lean as 7.4
Hello, i installed an innovate wb02 system in a Evo7, with an innovate digital gauge and purchased a usb cable to connect the lc1 to my laptop so now i can read the afr not only from the gauge, but in evoscan as well and save the logs...
My problem is that the afr is reaching very rich values , i mean the maximum of 7.4 , i can even feel the smell of gasoline when i rev the engine...
I calibrated the unit and it reads around 14-14.7 @ idle and 13-12 when the car starts running... But @ WOT it goes to very rich values from 9 to 7.4 @ 20 psi boost;
I checked my tables and the engine is almost stock, i mean the injectors, fuel pump...
Any ideas? Injector scaling is 542cc/min
