I am trying to decide if I should plop down the money for the suite but I can't find any detailed information on what I can do on my engines. I have a 1999 Suburban 1500 and 1999 2500 truck both with Vortec 5.7s (R vin).
One of my trucks has a ECM service number 16263494
What I am trying to find out is:
1. What can I tune on these? ( I know a general question )
2. Can I tune the fuel delivery and spark advance etc....
3. Tune the transmission shift points, pressure and lockup?
4. See sensors in real time to diagnose problems?
5. Retask the ECM to control electric fans so I can get rid of the belt driven fan
Probably the biggest question. I have read I can upgrade my ECM to 411 but I need to know if I do that, does it mess up my ability to pass inspection here in Texas where they scan OBDs to pass the emissions (anyone in Texas to comment on this?). I am looking to tweak profiles and a few outputs (fans) but not disable any emissions items.
Any info would be great!!!!
