I tried to sell on ebay, no luck at all people dont know the brand LINK i dont think as they other dude said its a great computer, its a F-iNG awesome computer does so much controls, launch control, stall control, boost control, fuel ratios, for some1 out the that has a spare few hundred dollards it makes all the difference in the car. No i dont think you can use it on a RB20 , in my car i got the link ecu, than i bought an optional map sensor for $180 i think?? which let me get rid of my o2 sensor on the air pod. than i got the car tuned at like $120 per hour and NOTICED huge difference. Someone must want this URGENT SALE
