This question if for a Toyota Supra engine, but you guys know way more about the Power fc.. so I'll ask you..

The stock injector's are 370'cc. I have a set of 880'cc that I would like to install. I have the FC and I have the commander. How do I change the injector setting's to accept these new injectors?

Thank you,
Chris

 

FYI, you very likely will have a tough time getting the car to idle properly with injectors THAT much bigger than stock.

I'm not well versed in injector size changes, but I believe that's been covered - do some searching and see if you can find some answers.

Would the Datalogit help in any way? I dont currently have that, but I have been thinking of getting it.

 

If Datalogit is available for the supra Power FC then by all means get it. If all things are equal between FDs and Supra Power FCs you may be able to up the size of the injectors directly from the commander. Look to the screen that has the injector sizes on it, you should be able to change the injector sizes by using the "up down right left previous and next" keys on the commander.
In the FC-Edit software that comes with the datalogit, there is a screen for setting injector size and lag. Once you do that, the datalogit adjusts the base map to reflect your new setup.

Good Luck

 

I belive I have almost all the screens you do, except trailing and leading injectors (obviously).

I have looked at the injector screen, all injectors are at 100 percent. so I just need to lower it down to right around 42 percent?

370/880=0.42

 

Actually on the commander you should have a screen for injector size and it should currently read 370. If you can change it by means of the Up Down keys, you will be given choices. If 880 is a choice, all you have to do is select it and let the PFC do the rest.

You are looking at injector duty cycle, which is not the same.

 

After reading the power fc manual, i belive i got it right.. Ill let ya know when im done...

 

well i guess i did it wrong or my injecotrs are screwed up.. I couldent get it to run right... Im going to send these injectors back and try some 550's... Thank you for your help guys!
