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.

I contacted hondata about this, and they said they don't bother with the vx and don't even have fuel/ignition maping for it. That ecu is a rare bird, and I expect tweaking with lean burn will be very difficult, and potentially catastrophic to the engine. I am however very interested if anybody does play around with making their d15z1 lean burn more without issues. Bring on the mpg!
