Turbo Timer for the Mazdaspeed3
 

I religiously observe a30 to 60-second (longer after relatively hard driving) cool down period as part of proper turbo maintenance, but am now considering installing a turbo timer to automatically take care of the timed idling. On my short list are the BlitzFully Automated Turbo Timer,GReddy Full Auto Timer and HKS Turbo Timer Type-1, but I haven't found plug-in harnessesyetforany of thesethat are compatible with the 'Speed3. What turbo timers are you guys using or would recommend? Also, does anyone know ifinstalling a turbo timer will void the vehicle warranty?
