ls2 tuning I'm new to EFI live (I have only been tuning my Duramax.) I installed a 224/230 cam, L92 Heads, L76 Intake with 40 lbs injectors and a cold air intake in my 2006 Trailblazer SS with an LS2. I'm looking for some help with tuning this, Any info would help. Thanks

The LS2 idle and ve is nasty, especially on the E38 its all filters and constants and 3rd order calculations etc. No simple 2d tables.
Guys usually raise idle speed until it idles. IFR table is ok. But you are going to likely want to keep the maf and tune off that (& pe) for best results at the moment.
If you are good at math you can probably sort it all out.
Take a peek at the efilive forums on the geniv stuff as well as hpt ones.

ok, I got the Trailblazer running and idling good. Runs good but little to no
power gains yet. I pretty much have only change timing a little and calibrated
for the bigger injectors, Still have a problem with starting at normal operating
temp.(I have to crack the throttle) Looking in to the Auto VE tuning, and I
need some help with the wide band O2 sensor. What exactly do I need?
I found a local place that sells the EFI live compatable Innovate LC1 and LM1.
I can get just the Wide Band O2 seperate or in a kit. Is just the wide band
O2 sensor all I need to connect to my EFI live? Thanks
