O ok.....they must be wrong....
The UNICHIP gives the properly trained technician full control over the timing and mixture functions of most electronically controlled vehicles. Not only can mixtures and timing be set, but also it can be set under various load and RPM conditions. This gives one the ability to optimise the vehicle for economy under light load conditions and set it up for optimum performance under full-throttle conditions.
The UNICHIP is much more than just a "chip". In actual fact it is a fully functioning computer which is added to the vehicle’s existing engine control unit (ECU). Apart from controlling general timing and mixtures it can do idling control, drive extra injectors, take full control over timing functions
Nistune
NIStune uses emulators or one of our daughter boards along with our specialised software to provide tuning capabilities including map tracing and real time editing of maps, constants and tables for your Nissan ECU. All changes are made in real time so you can feel the engine change and watch the outputs from the all sensors while adjustments are made
Seems to me both are a bit the same, nistune seems to be more advanced and a great product!!!!! but.....basics is the same.....
they are both daughter boards(fully functioning computer & daughter boards).....chips..... 😉
