Injector Duty Cycle Values

Used only on the 03/04 Marauder but can be used on any 03/04 ecu with code changes. Uses newer style SCP array so will not control cluster correctly on 2004 and older fords that use the older style SCP array such as mustangs.

Injector Duty Cycle Values

Unread post by p4ndiamond »

On This strat how do you determine injector duty cycle from the provided values in the log ?

I can log pulse width and that value seems unconverted. I guess id need to determine the injectors max pulse width ? Really not sure .

This question holds true for the fuel pump duty cycle as well . Values appear to be half possibly ?

Attempting to get a solid line on how these work for logging and troubleshooting . Thanks !

it logs automatically on the dashboard

yeah the pump duty cycle is half that's how ford actually does it. The adx update from 2020 has fpdcX2 to make it dummie proof.

You must be using a severely outdated adx.

RZASA 200510 is the base adx used currently for me

With RZASA 210517 XDF .. i swore there was a newer XDF than that you sent before but i coudlnt find it . let me see if i can find fpscx2
Is injector duty cycle such as pictured 0.70 = 70% ?

looking at my values they appear to be half for injector duty cycle on logs. No way the PW of those injectors is that low . So i assume its likely half but i do want to verify the math there lol

do u have a 27mhz 4.0 clock or 3.0 clock ecu? make aure u right click and select the correct duty cycle to view

No need to verify, its correct thats the beauty of using tunerpro.
