I wish there were some tuners on here to ask if it was possible to set something like this up with emanage ultimate which seems to be the easiest option.
Since my engine already has lean burn I just want to control when it happens with my own settings, not with the stock ECU. With the stock ECU if will kick you out with intake air temp changes, TPS going over a certain amount, etc. I would love to have a more free running system for when I am driving on the highway.

We have a tuner in Utah that does incredible work he had two different tunes on my car one for E85 and one for 91 octane and can tune for each gear and load and use outputs to run boost controllers and in your case EGR valve and activate a lean bur tune and a normal tune and you can switch to each tune with a toggle switch but you will need to convert to Obd1
The tuner's name is Cortney Green you can Google his name and you can see his work
