The Hondata S300 is a prime example of how new technology has been able to push the limits on older hardware.  It’s versatility allows for optimal tuning on something as simple as bolt ons all the way up to high horsepower setups that can utilize coil on plug with up to 8 injectors. The S300 is a daughterboard that is set up to fit within the body of a common OBD1 ecu to power up your D, B, F, or H series engine. Communication to the unit is as simple as plugging the supplied USB cable from the S300 into your laptop. Hondata’s S300 contains many features that far surpasses any Honda tuning solution within its price range.
