EE Hack - End of Injection Target table

[turbo_bu]

I was wondering if anyone has had any luck tuning larger fuel injectors with larger duration camshafts to reduce the rich exhaust smell at idle. On the LS PCM's there is a table which controls the end of injection target so you can fudge when the injector pulses. It doesn't cure all of the rich smell, but does make it more livable in a daily driver.

I noticed on one of the older EE Hack XDF files, there were a couple of tables labeled as 12df1 (ramp out multiplier) and 12df2 (EOI Target vs. coolant temp). The current XDF file (V4.1) doesn't appear to show those tables. Has anyone had any success playing with adjusting when the fuel injector pulses? Did this functionality even exist in the old LT1 OS, or is it just in the newer LS PCMs?

Without re-reading the whole thread, I'm just posting this link:

Yep. I've found moving the EOIT from 180 to 163 degrees sweetens it up a little.
Hex &60 changed to &63
(depends on which XDF you use)
