Yes, my idea would be an opamp confgured as a summing amplifier, with the= wideband on one input and biasing voltage on the other=2E

<= div dir=3D"auto">The TPS sounds simpler, if that will work=2E

The O2 sensor outputs a voltage but = very little current=2E  That would make it difficult to bias it in a p= redictable way=2E  Biasing a buffered output such as a wideband O2 uni= t output would probably work=2E

Any reason (other than the need to run 'closed loo= p' all the time) to not use a bias voltage added/subtracted from the O2 sen= sor output, to control mixture?
