Is it possible to run 2002-2005 2.2ltr Ecotec engine's in OL-mode? I just built a stand-alone harness and I'm trying to figure out if it's even possible to run these motor's without an O2 sensor...I wonder If I unplug O2 sensor if it will just default to OL...
Anyone?
Here's a tune file I'm working with...
No one? :unsure::unsure:
Still trying to find out if OPEN LOOP is possible for Turbocharging a 2.2ltr ECOTEC...
I think my P10 defaulted to open loop when I unplugged the O2 sensor, maybe try unplugging it and see what the fuel system mode is in the Scan tool.
Thats my last option...:D
Thats your only option. Im running mine in open loop no problems . Just disconnect the o2. Watch it with a wideband.
Also some guys are swapping in a 97-02 L4 big pcm from a s10 or cavalier, and running there ecotec with it.
To bad you dont have the other tuning software. You could flash in a factory LD9 supercharger file, from a cavalier. It would be great for what your running, being a standalone.
Really??? That sounds better than this P11Quote:

If you use a flex fuel file, injector flow rate is in there. Efilive forgot to include injector flow rate in the non flex 97-02 pcm. Also from what I see there is no injector flow rate in the 02-05 ecotec pcm supported either.
