Hello - How's it going?

[In-Tech]

I have many many programming devices, this is the cheapest one and use it with its' software as a generic scanner for non GM stuff. OBDLink SX usb version $39.95 including shipping in this ebay ad.

Keep in mind this and other "elm" type devices are extremely slow so make sure your battery is full.

I'll have to look into that one (OBDLink SX). Thank you.

My primary goal is to disable/remove Passlock/VATS(or whatever the security stuff is) from the ECM so I have a running engine. My secondary goal is to edit the fuel tables and timing and set it up for racing in the '85 TA and twin turbos for my '65 Impala.

I also use a bench setup, so I don't have to do any "initial" programming inside the vehicle.

Has anyone had any luck using EFI TunerStudio on a GM ECM? I have a registered version that I used when I was using a custom built ECM for an old rally car I ran.

Hmm... I believe that software is used for Megasquirt? If so there are technical reasons why that question is not valid. In some ways it is similar to asking "Has anyone had any luck using a map of Dallas to navigate San Francisco?" In other ways it's analogous to "Has anyone had any luck using passenger pigeons to send a fax?" In the first case the information in the GM ecm is not arranged in the same way as the information in Megasquirt. In the second case the method used to deliver information is not the same between the controllers.
