Chuck,

What are you going back to then? the .04 like you posted earlier in this thread, or leaving them at 0.0?

I'm about to send mine back to Ray for the 1300 injectors, I'll post what he changes on mine.

Just wanted to confirm about changing the pulse correction factor to 0.4...

first off, the PowerFC manual gives the pulse correction factor in terms of %, so it'd be 104%?? I don't have my car handy so I can't confirm that it really is in % or otherwise.

Second, the manual says to only change the pulse correction factor for changes to the primary injectors, changes to secondaries are unaffected... so if you were going to 1200cc secondaries I don't see why there is a reason to change it...? Am I missing something?

Tim,

I am still running +.04 lag time correction for the secondaries and have not changed them since going there. After I get my UEGO testing done, I might try changing them while on the dyno.

The previous few posts were about Alan's primary lag time correction that XS did. I was testing it and it made made my car run crappy.

Is there any new info regarding the lag time for the 1300cc injectors??

Let's say we are running stock injectors and still want to richen the fuel to just the rear rotor, what types of changes can be done?

As of right now, the evidence about lag seems to say: that it affects the pulse width and not timing. Thus try increasing the lag time for the rear secondary injector.
