bump $400 shipped. Great unit to retard ignition timing based on boost pressure (great for cars boosting more than 10lbs). Ultimate safeguard from detonation (caused by weather changes, load changes, octane inconsistencies the list goes on), goes great with AFC's or any engine management system. Great for agressive tuning, or just added security on conservative tunes.
 
It is designed to tap the ign coils and overpower the signal if knock is detected so it should work unless the ems is also controlling timing. Did you have the FTC (fuel and timing) or AFC (air fuel controller)?
