EFI Live Custom Tables part one
EFI Live Custom Tables part one I finally got around to wiring the PCM for the EFI Live Custom OS.
The way it works is you tap into the Red Connector (there are two big connectors, one Red and one Blue), at Pin number 56.
Both the F-Bodies and the C-5 have this without any wiring. The F-Body the PCM is availible under the hood. The C-5 the PCM is hidden behind the Passenger front tire.
PCM connectors are available from eficonnection for .50 cents,
Crimp it, solder it to 18 gauge wire going to a toggle.
Run that wire to a toggle that will ground it when closed and your in business
EFI Live Custom Tables part two will be written mid Feb when 860 Performance and I try this out on the dyno.

As far as I know, it does not ground out IAT, it grounds the unused Ground on the PCM. You have to add the wire that GM left out to get this to work. You must then use a Custom operating system OS5 (which is a free Download) that works with EFI Live Commerical (either V1 or V2) that will enable that feature. The other thing older Operating Systems guys like me need to do is update to a newer OS. So I am going to use a 2002 Vette OS on my 1999. TAQuickness and the others at EFILive have a tutorial on how to do it. Its available at the EFILive website.
It does not have to be used for custom Nitrous tables either it was origionally conceived as being a hidden kill switch that would use tables that would not allow the car to run, or limit the cars abilities.
Once I have the OS loaded I will put up screens of the tables that are available. That will be early Feb.

After asking some more questions, Pin 56 is an unused ground (it is not an unused Valet PCM feature). The Custom OS to enable and use this unused ground is exclusive to EFI Live. As competitive as EFI Live and HPT are, the best place to ask if HPT will be able to do this in the future would probably be the HPT forum.

So... let me try and understand. You ground pin #56 and EFI live stops using your regular spark & fuel tables, or something, and uses, say, nitrous spark & fuel tables instead?

As far as I know there is at least the fuel and spark tables.
I have to compare my 99 OS "table for table" on the swap to the 02 OS; then I will flash the custom OS and merge it with the 02 OS and have access to the alternate tables.
I am learning as I go so bear with me on my limited knowledge.
So, it looks like you could take out the needed timing down low (highest cyl pressures) and then add some back once you get rpms up a bit, if you have the dyno to work from. Or, maybe use your kr log to take out what is needed where, rather than a set amount linear from start to finish.

I can run either hundred shot on the NA tune and not pull any timing. When I hit both stages I want to pull timing.
Also if the car is going into the shop, I can use that toggle as a Valet mode, and limit the RPM/speed the car can be driven.
