well, what from 93 uses a 7727 with the code mask you want?

[ForcedFirebird]

So far, I haven't seen more than one pinout, are there more than one pending mask?

[robertisaar]

7727's can use a LOT of masks... have any idea what your printout is from?

[robertisaar]

3E, 46, 55, 6D, 88, 89, 8D, 8F, A1....

choose your poison...

[ForcedFirebird]

The plan is to use $A1

[robertisaar]

these are from a 92 lumina 3.1, which unless i'm wrong, is A1...

saw some of the J-bodies with the 7730 and A1... almost sent those

i certainly am a productive member of this community...

I believe that is the first year of the 4l60-e since it has no TCC control yet has 2nd, 3rd and 4th control. Probably could use 4th gear for TCC? Also not sure what to do with the Camaro's secondary AIR relay (B3), A/C status (C2), or the 24x crank signal (C21).

The car needs to pass a visual and sniffer for inspection, so as much of the emissions needs to remain as possible, specially since it will now be MPFI.

I will upload what I have so far, take a look.

EDIT: and I'm trying to be productive, just need to get this figured out and tested for others to follow

1993_16172693_to_1227727.xls

EDIT: After thinking about it, the 24x can be dropped since it is no longer SFI

[robertisaar]

Another All Data request

1993 Lumina 3.1 ('9396 ECM). It's supposed to be the same as the '727, but just want to make sure since I picked up 2 '9396's and 2 '727's for the project.

Thanks!

OH, and does All Data do foreign cars?
