Its factory calibrated and the 0-5v analog outs are well documented in the manual, I dunno what else you would need.

I just got mine, was wondering where everyone brought that massive connector thru the firewall...?

same one I got. I used the plug above the pedals to get that massive connector through but you can depin the connector if you wish aemforums have instructions and also have a pinout incase you mix them up!. 0db you have the AEM ems also right? have you gotten that installed yet?

Yeah, I've been running around on the EMS for a few weeks now. So far, so good. I don't think I'm making a lot more power than stock engine management at the moment, but I've got it reasonably smooth and driveable, and decided I wanted to get all those issues ironed out (this is my daily commute driver) before I tried to push the power up. Once I've got the gauge UEGO in there, I'm considering going to a closed-loop fueling for cruise/vacuum operation. Need to keep that fuel economy up these days!

the aem base map sucks if you want to run closed loops o2 feedback. You would need to convert to a 3D map from the boost comp map. I am working on this right now so that I can use closed loop to get it tuned to a desired AFR until I can get it dyno tuned.

Technically there's no reason you can't run boost comp AND fine tune the map in 3d... I actually let autotune do that a bit, it smoothed out some spots that I had trouble isolating with just boost and throttle comp.

your right there is no reason you cant use boost comp and make the map 3d but it could get a little complicated.

What I was actually doing is logging the changes the autotune made, and trying to find a way to accomplish the same thing by tweaking the boost comp and throttle mod maps. All does the same thing in the end, I guess. Just interesting to try different approaches.
