Injector upgrade settings

[XPS]

I just upgraded my LS2 to L92 heads and LS3 injectors.

I re-scaled the injector flow rate by multiplying 1.2, which gave me the same chart as a stock LS3 tune I got from the repository. I did notice that there are still many differences in the short pulse adders and min injector pulse values. The scan I did looks fine, and the car seems to be running good and strong.

My question is, do I need to change any of those values, or should I leave everything else alone since it is running well?

Thanks for any help.

Yes, absolutely you need to change them!!! Do not listen to anyone else who tells you that you don't.

Just use the *exact* values from the a stock C6 Z06 from the same year model you have.

Basically, do this:

2005-2006 LS2 = Use 2006 Z06
2007 LS2 = Use 2007 or 2008 Z06 (or 2008 C6 LS3)

Copy the following:

Any values different under "Injector Control" section (Offset vs. Volts vs. VAC, Flow Rate vs. KPA, Short Pulse Limit, Short Pulse Adder, Min Injector Pulse).

Note, the "Offset vs. Volts vs. VAC" table will not be in the 2007-2009 vehicles, but instead "Offset vs. Volts vs. IGNV" table replaces this.

Speaking of IGNV...what does that mean? Is it the same as the vs VAC table? Or does it work differently.

IGNV = Ignition voltage.

Given you have the luxury of having access to the exact injector properties I would definitely use them. Changing the other injector related tables to match the LS3 values will ensure they work as they should under all conditions.

XPS, what year do you have?

It does the same thing.

It's an 06 C6.
