If yes, then you must know the lag times of the standard injectors in order to properly setup the offset and correction for the larger injectors?

Someone care to enlighten me as to what those lag times are as Im about to put in larger injectors but need to know this information to setup the PFC.

 

The power FC already has the lag time for the stock injectors. What you need is the lag time for your new injectors so you can scale your map. I'm running 1000cc with the FC. Let me now and I will see if i can load my settings for you.

 

Im putting in some 680cc Precision Turbo injectors, lag times are 1.13ms opening and 0.998 closing.

I was hoping to get the standard Evo 560cc injectors lag time (as i believe they are different) so I can setup the offset and correction values.

 

16v .628
14v .748
12v .928
10v 1.208
8v 1.688
6v 1.900

That is the lag at the corresponding voltage for the 560cc's. Now you need to know at what voltage the lag time is 1.13 ms so you can properly scale.

 

MXJS thanks for the info !!! Just what I needed !

Ive sent an email to PTE to find out what voltage the 1.13ms measurement was taken.

 

not a problem, are you using datalogit?

 

No, Im not using Datalogit. To be fair I not that familiar with datalogit but have seen it mentioned numerous times.

My mechanic, does my on road tuning and mapping. The car runs great and has a fairly consistent AFR @ WOT when mapped last, however I am putting in the 680cc injectors as I have gotten a 100% injector duty cycle reading on the commander when getting close to redline in 5th gear with the 560cc injectors.

Oh and on the slim chance anyone else is looking for this information, the 680 PTE injector lag times are based on a 12v reading...well so I have been told.

 

Hi! What is the lag time for the 560cc?
