As far as we're aware (and we're pretty well connected to this scene) we are the first company to successfully map out the EGR valve on the Honda ICTDI, and this is completely within the maps (no physical modification needed).
Honda's EGR implementation is unique in a few ways and closing it off within the maps, and adjusting fuelling etc plus mapping out some specific direct and indirect errors was required and took a good few weeks of testing to ensure it worked. My Accord is the only one running it and has been for some 4k - 5k miles now, and the only other car is a Civic we tuned in ireland.
It's now available for general release to our mobile tuners.
We are aware that other companies tried and failed, some even resulting in disabling some safety features and cruise control functionality in the process.
