I used this in my first build, it's run maybe 5-6 hours total, and now it's been sitting for years. Here are the specs: http://www.linkecu.com/products/engine-management/lemg3-whatdoesitdo I have the original box and manual, it will come with a Bosch IAT sensor, and it has the harness with about 1ft of wire and the plug. I'm asking $700 obo, possible trades for a springfield XD, Glock.
