Has anyone thought of using an AEM unversal EMS to control the timing and fuel, and leaving the factory computer in place to control the factory drive by wire.  We are doing this to our drag X. 
Let me know what you guys think or any ideas.

yes, it will work as long as you install an external trigger wheel and sensor for the crank

ok that is not that hard to have done.  I have a fabricator local that can make a bracket for the sensor and center the trigger wheel on the light weight pulley that is already on the crank.

it's easy... just take some aluminum L channel and make a bracket;











takes a couple of hours to build, the trigger wheel only needs SLIGHT hand-filing to get it to fit.

Don't worry about using AEM's universal box, you can do it far far cheaper using another box.  Off the top of my head your cam and crank signals use hall effects which would mean that there are a number of AEM boxes that you could likely use.  The AEM 1050 box was setup for mag sensors but has jumpers that allow you to use Hall effect, the 1310 and 1300 boxes for DSMs have hall effect sensors, the 1052 box for an S2000 has hall effects, etc.  The software is the same for any box, and you have to wire your harness for a universal box anyway, so it wires up just the same as a "plug n play" retrofit would.  The things that the universal box has is direct speedometer control, dual wideband inputs, 5 ignition outputs, etc, but the 1050 and 1052 boxes both can have almost all of those features and cost FAR FAR less.  Typically a 1050 box can be had for around 800 bucks off of ebay.
