a question to the experts......pros... and those who know... ;-)
One more question.... what could I expect from a wideband o2 sensor and autoVE tuning... goal should be to get the AFR leaned out / more accurate in comparison to the OEM narrow band o2 sensors..
Is there any way to get a kind of open loop / lean cruise in no / low load areas?
To the sensor.. If I look over here in germany I think I should look at Bosch? Any suggestions on a special type?
Then, will the wideband(s) remain in the exhaust instead of the two OEM ones in front of the cats? Or is it only for calibration purpose and to create a correction table? Then, if I understand correct I have to install 2 widebands, one for each bank?..... I think I am confused..... at least a little bit.. which is quite usual..
Platform is a GEN IV 5.3 LMG E38 controlled engine in a 1997 Tahoe which has bad fuel drinking habits... see:
