Title: why my injectors are over duty cycle
Post by: tao13 on November 05, 2018, 02:35:54 AM
Hi all.
Anybody can give me a reason for why my injectors are over duty cycle at the red line.
I have 386cc at 3bars with 3 bar standard fpr. All table in my ecu file was modified for these injectors.
LTFT and STFT works greate.
I saw my lambda follow LAMFA.
Can be my fuel pump or my injectors?
I attached my log.
Many thanks in advance.

Because you're running out of fuel?  Log fuel pressure.  What boost?

The injectors are not enough if you are maxing them out, why not run 4 bar?

forthe moment i tried standard injectors from bam engine because i had all map from original ecu file and was calibrated ok.
the strange thing is effinjtime is 16-18% but duty is 100% when the boost is 1.0-1.1bar
about fuel preasure i think my ecu doesn't know this value to log it.
will try with a new fpr 4bar

You should measure fuel pressure with gauge @wot

will try , i have an fuel preasure regulator with gauge but i must modify my fuel rail
thanks for your answers
