Avcr Injector Duty Cycle.

[W0rp3D]

just put on a high flow (had to replace my standard turbo as it shagged its self) and was looking at the injector duty cycle on my avcr, it seems that at low throttle that the % is around 90 but when i boot it seems to go down to about 30, is this right, does the % show how much of the injector duty cycle is not being used?

i also noticed that the peak hold shows the higher %.

also what is the (if lowest % is worse) lowest i should take the standard injectors, fuel pump, afm and ecu to?

i have a pfc and z32 afm, need to get fuel pump and injectors then tune it but untill then i want to get the most i can out of it safely, atm im running about .6 bar (9 psi) would like to up to .8 (12 psi) but also want to keep it safe.

any help would be appreciated.

Well 80% is considered a best practice ceiling... doesn't stop countless ppl hovering around 90% - 95%

If you right, and the #'s are inverted... I guess 10-20% would be what you'd wanna keep it under (over?) lol

Rem, thats at max load (airflow) the motors ever likely to see. Ppl keep that safety margin in case of a cold night, or a serious over boost.

i guess i should also presume that the avcr is not 100% accurate and keep it to the (inverted) 20 - 30%

I have nfi about the Avcr; is there an option for flipping the output?

dont really know, have not played with it much as untill yesterday my turbo was shagged, will play with it tomorrow and see what i can find.

if u have power fc why not just use the map tracer or use the display to show injector duty

so i take it u dont have rpm in your avcr?

^^ phhft, i fully missed that.. oh dear

i have a pfc and z32 afm,

i guess i should have mentioned that i have them but im waiting to get the rest and fit them all at once then tune it.

As above, use PFC for inj duty cycle.
