hachoo Posted April 22, 2020 Report Share Posted April 22, 2020 Hi guys. I am little confused as a stock ca18det injector is 370cc low impedance(peak and hold) and its on 14ms master fuel on link G4 Storm which means if i change to 700cc injectors high impedance( saturated), it would be around 7.4ms, am i right? But if i were to change it to 7.4ms, my afr reading is too lean. it is afr of 21 may i know whats happening? my car was tuned by some other tuner last time. it is on a ca18det. based on the map, it is at 14ms with a 690cc low impedance denso injector previously. but, i realised my injector resistor box is not there anymore, so i changed the injectors to a unknown brand 700cc high impedance injector. may i know what i must do? do i change the master fuel? or based on 14ms, i change the fuel table again? because after changing the injectors, afr is around 21 Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 23, 2020 Report Share Posted April 23, 2020 So was it all tuned on the 370cc injectors and running well with the master at 14ms? Quote Link to comment Share on other sites More sharing options...
hachoo Posted April 23, 2020 Author Report Share Posted April 23, 2020 it was tuned on 690cc injectors and running well at 14ms but it is low impedance injectors and i do not have ballast/resistor pack. so i have changed to a 700cc high impedance injector now.

Adamw Posted October 5, 2021 Report Share Posted October 5, 2021 Just adjust the master up or down until the air fuel ratio reads somewhere close to target, then the fuel table will likely need to be retuned. Quote Link to comment Share on other sites More sharing options...
