When I used the DW1300cc injectors, the P0300 code popped out everytime I drove my car. I tried lots of methods but still couldn't get rid of the code. Therefore, I contacted DW and exchanged to the new DW1000cc. The new injectors do come fast. Today, I installed the 1000cc, but when I light step on the gas pedal, I can hear a electricity noise which last for one second comes from the injectors (The noise was not there when I used DW1300cc). In the video, I light stepped the gas pedal several times, and you can hear the noise clearly (not the constant ticking noise). I ignored it first, and went for tuning the injectors. I tried everyone's scaling in the forum, but none of them work. I also adjusted the scaling by myself, but no luck at all. For example, if the LTFT idle is 1%, and LTFT cruise will be -12.5%. If the LTFT cruise is -4%, the LTFT idle will be +10%. No matter what I did, the idle and cruise will never come close. The good thing is the P0300 code doesn't pop out anymore. Do people who installed the DW1000cc also have the electricity noise? Is there a problem with the injectors? Thanks for helping me

Bigger injectors = bigger solenoids = more noise.

 

I had the DW1300cc before, and I didn't hear that electricity noise before. I understand there are constant ticking noise, but not the electricity noise when I light step on the gas.

 

Holy loud!!!! Mine were never that loud (1300's), I know have stock ones back in temporarily.
