tygen1, can you give any details about how you have set up your lean burn, where the voltage dividers go, what values ...
also how have you gotten around closed loop operation, as far as i know when changing the MAF sensor output, it works when in open loop so until the o2 sensor heats up but as soon as its warm and sending back usable voltages the car goes into closed loop mode so stops looking at the MAF sensor.
I ask as i am trying to do lean burn without buying a wide band o2 sensor and controller.
Also when i started going lean using my standard narrow band o2 sensor i had to increase the idle control screw so that the car wouldn't stall, have you done this as well?
