Do you need O2's? 2 bar SD
Do you need O2's? 2 bar SD On a turbo application, HP Tuners 2 bar SD operating system... what do the front O2's do? Can I leave them out? rears are already long gone and shut off.
Fronts are closed loop. If they are out you will be running 2bar SD OL. Some people do it some don't. Most people who do are usually purpose driven cars. I myself am running 2 bar SD with front 02's.
Reason I ask is my friends BMW we are building, we went through the harness and eliminated all the unneeded wires.... and I think they got eliminated. It would be a pain in the *** to probably rewire them. Just wondering if it will work w/o. Would it just take longer to tune and dial in the VE table? Like you'd have to tune it with each weather change?

Front o2's I have found are easily fooled by weird cams and non pump gas, so I would ditch them in any case.
The problem is that with SD, your tune is going to be weather effected WAY more than a MAF tune would be, so the front o2's would help if you are going to do a 100% pump gas / stockish cam setup.
maf + no front o2's = awesome
SD + no front o2's = not so much.
