can anyone tell me if i can load hondata s300 onto my p28 ecu? I have a 95 cx hatch with a full b18c1 swap, but i dont know what tuning program is currently on there, and i've heard that without knowing that, its hard to know if you can do it. But ive heard that hondata s300 would also make my engine perform a lot better just due to how it is programed

 

You don't "load" an s300 you install it....it's a circuit board so to say, it will fit into any obd1 ECU that is "prepped" for it. On a stock engine it's pointless really more so and being around 700$ after install. I have one and like it for many reasons but the car is far from stock/DD, for you i'd suggest getting a chipped ECU insted with a basemap for your engine.
