you can make it all work, but it will require a good bit of extra work. I run an AEM EMS v2 and have traction control, Cruise, even passed emissions. (this is really hard to do btw and usually takes me a month or so of tuning constantly to get it to go right)
from what i remember about the dezod is the CEL light is cut, reconnect it, build an ignition simulator, and make sure all your o2s are plugged in and working properly, along with all other stock sensors. You can do it. i also recommend a zener diode in the maf circuit to prevent it from maxing out and throwing a CEL. I recommend an ecu reset relay but this will prevent you from passing emissions.
