Hmmm... I'm a bit skeptical about the whole idea but "maybe" it will work as long as the altered signal looks exactly like the NBO2 output and shows a slightly lean condition. It may throw a CEL though....

Here's your biggest problem.... The optimum AFR for making power is around 12.5:1 the stock NB02 sensor won't even come close to reading that.

In my opinion, the best way to do this would be to bypass the factory ECU and use a WBO2 to control the EHA directly. Optimally you'd also need load and RPM inputs but by then your basically looking at EFI. Theirs not many hidden patches to engine management other than reconfiguring everything. With what you are proposing, it sounds like a minimal power gain with the possibility of a CEL.

Take my post with a grain of salt however. I'd hate to get your hopes down and would like to see your results. I'd personally love to see you prove me wrong. Gonna need to see some dyno charts though!

Good Luck!
