Hello i am New here and this is closest place i see to ask this, if i am wrong please let me know . I have a friend that has a 2000 k3500 7.4l fuel injected auto. Can this be tuned. I did put a new (used) knock module in it (Knock Codes). It did help some but motor is fresh with new heads and this thing is a dog he had a programmer on it but cant remember what it was and he sold it awhile back. Is this a em3494u pcm pcm # is 16208991, and what is needed if anything to flash back to stock or tune it please. Cant seem to find any info via google search. How can i read pcm like in ls droid or other free stuff i dont have HPTuners yet.

This thread is about using an OBD1 computer. (no worries)

The 2000 K3500 uses an OBD2 computer. (again - no worries)

Maybe information in this tread will help: http://www.gearhead-efi.com/Fuel-Inj...d-is-TunerPro)

I would use my EFI Live system to tune a 2000 K3500. Is EFI Live the low cost programmable option ??? It would be the programmable option for me.

This Truck is getting a Holley Terminator X Max integrated with the factory ECM. I will be using the factory ECM for factory gauges primarily.
