wish: allow user to set a "desired A/F ratio" and have the
ecu learn/adapt (with wide band o2 sensor) regardless of
changing mods or car/weather conditions.

AEM is doing exactly that for the evo, so I'm dreaming...

here's the excerpt from overboost's day 3 sema coverage:

Here's something will throw into the "ultra cool" file, a low-cost air/fuel controller for wideband oxygen sensors. Gone are the days of paying like $1,500 for a bulky box of a wideband setup because AEM's new wideband controller resides in a gauge-type housing for easy mounting. One killer feature is that the controller has an output that emulates 1.0-volt oxygen sensors. What this does is allows you to replace the stock oxygen sensor (instead of keeping it and adding a second, wideband sensor) and the controller takes the 5.0-volt output of a wideband and condenses it to a logarithmically correct "steep slope" 1.0-volt output. This keeps your stock ECM happy and eases tuning. AEM has also developed a plug 'n play stand-alone ECM for the Lancer Evolution. It's a plug-in swap for the stock ECM, is fully programmable and uses wideband oxygen sensors. (This thing can actually self-tune; all you do is key in the target air/fuel ratio and go for a drive—the ECM adds or subtracts fuel curve as necessary!)

ps. if I had spare money, the evo is very tempting. a new front
fascia, ecu piggy back or replacement and bam, low 3x0 awhp.
Would be a great car to have if you already have a touring car.

 

that's freakin awesome, best thing to do is contact AEM about it, and ask them to do a Z application.

 

It won't be nearly as easy for ours because our car is setup for NA and has no stock MAP sensor, but here's a second to that wish anyways.

 

Third.

 

since their ecm was meant for the evo, just replace with
a sensor than can sense boost (from the evo?)

 

dude you're selling your car....

 

But Vic I'm in the same boat as you.

Also I just think it'd be a cool gadget for Z owners.

 

the AEM ecm has been out a while now for supras and boosted honda/acuras as well as other platforms i'm sure. very nice from what i've read, but its not all that easy to setup and you better know what you're doing or kaboom.

 

I spoke with AEM, and they have a universal EMS coming out that will take advantage of their wideband O2 setup. This should be interested....BTW it is a stand alone unit, it completely replaces the factory ECU.
