Hello, can anyone point me in the right direction as to why my injector duty cycle just dropped like crazy around 5k rpm? It only started once I upgraded to a 20G turbo.
I had the stock fuel pump and it did the same thing so I swapped it to a AEM 340lp. I had 550cc injectors and swapped them to 750cc and it is doing the same thing with the upgrades. I swapped coils and plugs and the same thing. Oem coils and ngk plugs.

New motor in and doing the same thing.. anyone got any input? i am starting to think its the injectors overloading?
Well i finally got a good pull in. Maybe if i would have noticed it better before i could have saved the old motor...
To much fuel was dropping putting spark out as you can see in my hpl file.
I need to figure out how to control spark better... I have changed alot on this car but I have not figured out how to control spark yet in the areas that i want it done at. Still pushing forward! good luck to anyone else around with the same issues and keep pushing.
I seen this before.. if you need a remote tune lemme know
quick fix.. turn off any FUEL SHUT OFF SETTINGS.. disable in your tq managment to start

I have tried this but no difference. I just changed to the Caliber srt 4 injectors and now spark seems to be back in the negatives again. I will be trying to sort that out. Also I looked a one of my previous tunes with my old motor and spark was fine and it did the same thing so that is confusing.
Now i am trying to get idle and part throttle under control. as i am getting a cel for high idle.
I am interested because i am over this lol
