I'd probably hold off on ordering this if anyone is considering it. Seems they're having some issues getting caught up from a personal issue and these aren't actually in stock from what I was told. They said since the parts to make them are in house, they consider them in stock. There are status update pages explaining the delays.I'm guessing your cable is the problem. This one should work:
BoostedNW ALDL 12 pin GM datalogger
This is for any pre-1995 (OBD1) GM vehicle. Everything except the 1995 LT1. You should be able to datalog all of them, and reflash the 94 LT1 as well. This item can be used with TunerPro RT, TTS Datamaster, TunerCat reflash for LT1, WinALDL, and EFI Liveboostednw.com
It's been 3 weeks since my status was updated to packaged for shipping...little over a month since I was parted from my $...
I reached out again a couple of days ago . Will see. Was hoping to have a new cable before I go oot next month. May have to get that other one recommended and just wait this one out.
