I am reading a Tuner Cat file for a 1993 Y Body, ECM_DA2. I am trying to find the minimum injector pulse width table. ANy idea? The only one close on my tables is "Injector PulseWidth Correction vs Battery Voltage"
These tables are as follows
VDC / usec added
.0 977
1.6 610
3.2 610
4.8 7782
6.4 7782
8.0 7782
9.6 7782
11.2 6836
12.8 4486
I am looking to lower my minimum injector pulse width for idle characteristics.
Currently my idle is around 2.0-2.3 MS at 925 rpm in my 396 LT1

 

The table you're looking at is a correction to the PW calc'd by the ECM. If you want to affect the primary PW calc, wouldn't you lower the VE?

 

I am fairly new to this, and need to know if this is the table to change and how much to lower, or allow the idle pulse width to lower down a little.

 

Okay, UPDATE
Tuner Cat sent the new definition update for my year. Apparently the 93 DA2 is already set to a minimum pulse width of zero anyways.
