I went ahead a bought the full version of EFILIVE scan/tune. I got a free email tune from the tuner that I bought it from. I am wanting to fine tune the ve tables on my 08 5.3 silverado and I am looking to get a wide band for accurate tuning. I am confused on what to get? I see the LC-1 from innovative. I can get the cable or the cable/o2 sensor.
Questions:
If I get just the cable do I hook it up to the pre-cat stock 02?
If I get the cable/sensor do I replace the pre-cat 02 with the new sensor or do I need to get a bung welded in for it before the cat.
If I do install it before the cat would I need another one for the other side? the trucks have 2 cats right after the headers that merge into a y pipe.
I also have the dynatech long tubes with their high flow cats and y pipe.
thanks,
Larry
