You'd probably need to adjust the O2 sensor's output so that the ECU thinks its running stoich when its actually running lean.

Here's some interesting info:

There is a circuit that can be utilised to adjust the O2 sensor output, but I can't find the link.

And available from the designer here http://www.eagle-research.com/store/...products_id=16
