AccessPORT, a handheld ECU programming device which connected to OBD-II port on cars, launched in 2004 is their most popular product because it is the first one to crack Nissan GT-R’s ECU code that was said as “untuneable”. They also develop a software for engine tuning, AccessTUNER which is available in two variants: Race and Pro. The Pro version is available only to COBB approved shops and tuners.
