For the money and for your application i think the AEM EMS is way too much for what you need. I personally would recommend doing a uberdata/hondata type setup. I am running a chipped p28 setup and I love it. Im not running uber or hon, im running chrome but its the same basic concept. I have most of the tunability of a standalone and payed only a fraction of the cost (55 for ecu, 20 for chipping, 100 for dyno tuning).

So, my vote is a hondata/uberdata setup.
