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

 

RACEON, I have a '94 "EE" definition file it's different from yours, but maybe close enough to help.. The Minimum Injector Pulse Width' setting for the EE definition file is in the Constants settings about 17 rows down, not in a table. If this doesn't help possibly try the http://www.monodax.com/forums/tunerc...ware-software/ forum ? or the http://www.speeddensity.org/forumdisplay.php?f=25 forum for '93 LT1's.

 

I don't see anything like that:

I think the only thing I can do is change VE tables around idle, to lower the injector pw by changing the fuel requirements.

 

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.
