The posted image are the injector compensations pulled from the BDZL calibration. That is an f-body 5.7l engine.

Yep, that matches what I have from my BDZL (TransAm LT1 with 4 speed auto). For what it's worth (and not surprising) the BDLD (Camaro LT1 with six speed auto) as the same offsets.

 

I need these values for the 94-97 LT1 injectors they are 24lbs same as 1993 I initially thought 93 was 22lbs same as a third gen but the tune says otherwise, $EE also has a minimum base pulse width vs RPM parameter, since they are mass metered and sequential firing is there some sort of formula that needs to be taken into account when using 94-97 injectors in $8D? Also what is the effect of the low pulse width offset vs BPM table in $8D lower values = richer?

 

Here's what I have on $EE. It's the BKFS. I'm also showing 25 lb/hr for the flow rate.

What style injectors do you have? I'm not familiar with what they were running on the LT1's.

 

What about the low pulse width offset vs BPM table, these are the injectors I'm working with

 

Ok found the values but stumped on what I should use with $8D because for 94-97 there is another field for pulse width

95 LT1






For caparison this is 92-93 the minimum base pulse width is set to 0 via scalars



Looking at the two tables 92-93 vs 94-97 and 92-93 being speed density and batch fire would its values produce a leaner mixture because of the more time adder compared to 94-97 to compensate for the batchfiring? If running 94-97 injectors with $8D would it then be ideal to instead use the 92-93 compensation tables

 

Is there a reason you're intent on using the LT1 injectors? Seems like a set of Bosch-III's would be a good choice.

For example, the 0280-155-759 30 lb/hr, which is what I'm using.

In 8D, I then zeroed out Low PW compensation table. From what I've understood, that table isn't needed with Bosch-III's since they flow better at low PW's than the old Multecs.

Also left the minimum PW's as factory AUJP. Seems to run really well like that.

That said, I believe the values from the DA3 and EE port over to 8D, at least from my experience. So initially, if you're intent on using the LT1 injectors, I'd probably start with the DA3 values and see what that gets you (assuming you have a WB to see actual AFR).
