ok thanks

oh ok, it claims to do a lot but I am also skeptical. E-manage ultimate is probably a better choice it seems.

lol kk I will consult my inner self.

The 04+ Specs have the CAN bus wires behind the dash because they run to the gauge cluster.  The 02-03's don't.  I had to run wires directly from the ECU to my OBDII port. 

You will need two two wires.  the CAN-H and the CAN-L.  The 02-03 colors are blue and yellow.  Check your FSM for coloring. 

The Cipher software can change the timing base map and raise and lower your idle it can also log multiple sensors for a period of time.  You can also check and clear ECU codes, Monitor and record ABS Perameters, Clear you fuel trims, Adjust for Ethanol Mixture, do a cylinder power test, Check the fuel injectors, etc...... 

You can tune your car using the Osiris software it just won't do it on the fly.  So you would have to log then go back and change the maps then upload them back to your ECU. 

Awsome shit.  It is like OPEN ECU for us Nissan guys.  DOOOO ETTTTTT.  My only beef is no support for us 02-03 guys.

My mistake Osiris software is not available for the sentras yet.  But it will be .  LOL   If I had my choice I would wait.

Oh ok thanks a lot, do you mind if I ask you about these wiring during install? lol

I will do what I can, let me know.

I run the ultimate now.  Don't get me wrong, it is great. running 20psi daily with no problems.  But if I had the chance I would swap over to the Osiris without hesitation.  WAYYYY more control/options.  Of course there is the small problem of waiting but their sftware is getting there.....

no CAN wires in the OBD port for the 02-04s for sure. The G35's don't have them in the OBD port either. We had to add the pins so we didn't have to keep flashing the ECU on the bench with the adapter. The data stream that caries the reflash data goes through the CAN wires, the sensor data uses a different pin in the OBD port.

350Z's, Titans, etc have CAN wires going to the OBD port already, the B15's don't.

Verified on my 03.. NO CAN bus wires in the OBDII port.  Not even in the dash cluster.    Had to run them from the ECU.  Cut up a harness to get it all working like OEM.

What would it take for the 02-03 guys to run CAN BUS so that we could run osiris tuner??
