"The Realtime ECU uses a single USB connection that adds two new com ports to your pc when you connect. One is a standard consult connection (works with all existing consult software), and the other is the for the eumlation stuff. There are no ROM chips on the board, and you don't add anything. The emulation side supports a subset of the Romulator protocol, and EmUtility and TunerProRT both work great with it. The emulator protocol is also open if you want to write your own custom software (the command set is pretty straightforward). I use TunerProRT for realtime tuning, Nissan DataScan for map tracing and general consult functions, and good old CalumSult for datalogging.
All changes can be done 'realtime', while the engine is running. Makes tuning k-values and such pretty quick. You can also upload your bin to the ecu without the ecu being installed in the car, it will power off the USB port.
The consult circuit is also 'smart': if you have a consult device (techtom, n-probe, real CONSULT unit, etc) plugged in the daughterboard automatically shuts its own consult circuit off.
And thats all it does. No extra features, no bells and whistles, no firmware updates, just pure tuning.
The B13/S13 is $350 and the B14/S14 is $375. Both prices include install and return shipping (you ship me a core first of course). I also do demos at various shops (USA only). " "
If you've got more questions just post or give me a call (my cell is on the order form).
