[andrew]

hi there i have a evo 4 that is over fueling when its warm but when its cold it is fine to drive have had it on a scan tool and its all fine apart from the injectors staying open to long when it is warm there are no codes coming up can anyone help

Have you checked afr's?
How do you know it's over fuelling?
What mods on the car?

 

[Simon@NTS]

What's O2 feed back saying ?
Fuel trims?
Engine temp?

 

[andrew]

afr is fine o2 is reading fine. Everything is working as it should when you have it running with the scan tool plugged in apart from the injector pulse, you can see it staying open too long. Car has forged pistons rods and crank. Balance shafts removed and has a gt35 turbo.

 

[RsvRob]

You maxing the injectors out. Bigger injectors required...

 

[kenchenzo]

yeh agree you need larger injectors your pushing them to hard

 

[Simon@NTS]

What's the Idc reading when at cruise and full boost? What injectors you runing?
