injector offsets, 1993 lt1 vs 1994 lt1

[busta9876]

I'm working on a 95 lt1 swapped into an older 3rd gen, and the guy who owns the car bought a 93 LT1 intake from a corvette complete with injectors. I've installed them but off the bat it would not idle, very lean....I got looking at the injector settings and found some differences, but now its pig rich with these settings..and the offset on the 1993 LT1 calibrations seems HUGE...see attached. I see the same offset settings in tuner pro and CATS tuner. 4.516 ms (4516us) at 12.8 volts seems off.

If I load up a corvette binary with $DA3 it looks better...just thats not the correct definition for a vette file. 1.770 ms (1770us) that way.

any one had experience with offset (Inj PW Correction vs Battery Voltage)

I had to use the LT1 F-car offsets to make a 350 TPI with 7730 run with a set of LT1 F-car injectors.

humm....Tunercat shows no difference in the LT1 F-Body 1993 and LT1 Y-Body 1993 using the $DA3 for F-Body and $DA2 for the Y-Body. Tuner PRO DA2 does not list inj pw correction on the tables list....
