Hi - Well I have just go the Pro Version - I want to set it up for use on my 2003 YD 2.2 Diesel ETi (not DCi introduced late 2003) X-Trail - The port is OBD but does not have as many pinouts as standard OBDII, however I am encouraged by imircea getting the CG Pro to work on a Primera
What is the best way to set up the app for my X-Trail ?
Are you having problems connecting to the vehicle? From the menu, select Nissan ECM Diesel and make sure you select the correct Bluetooth Device. If not connecting, send me a Debug log. Enable it under Preference then exit app and email the log to me.
Once I got the hang of getting the app set up, when live, I set Nissan, ECM Diesel, and CGP reported 12 sensors available
I got the following results:
P0000 Powertrain - No self diagnostic failure indicated. I would want to check this against a vehicle with it's engine check light on, to confirm this.
I checked the vehicle info, nil, nada, none. This would suggest we have not managed to communicate with the ECU at a "higher level"
The good news is that CGP did get some data. PIDs available are as follows:
Accelerator Position 1 Accelerator Poistion 2 Actual CR Pressure Brake Switch Coolant Temp Cylinder Count ( 0123 as apposed to 1234 ? ) EGR Volumn Control Fuel Temp Intake Mass Air Flow RPP Target CR Pressure Park/Neutral Position (a manual goes to off when a gear is selected) Vehicle Speed Off Accellerator
Not sure what CR Pressure is, but I checked all readings at idle and driving. CRP also showed Baro, which remained static, but am not sure what that is either .
The device info indicated the ISO 14230-4 (KWP FAST) was being used.
Hope this helps. I will give you some more feedback on set up in my next post.

Thanks for your feedback. I still want to look into the debug log. Please, when you get a chance, enable debug log and display all of the data under data parameters. Data needed for vehicle info and check for faults, also.
Hi there Issac - I attach the latest log file. Engine running, selected all PIDs so you can see whats there. Took off auto and selected ISO 14230-4 (KWP FAST), then put back on auto. Hope this gives you a few pointers Let me know if there is any thing else in the way of info you need. Thanks Charlie
Intresting that CR is common Rail pressure, the engine is not common rail ? What is the difference between Acutal and Target pressure, I know it sounds a daft question, but I got a reading off both of the same 34MPa at idle ?
Where does the Baro data come from then ? Bearing in mind I am only about a 100 feet above sea level.
I am not familiar with Nissan system. I assume there might be a pressure sensor at the Fuel Rail or somewhere in the fuel system near Fuel Injectors. I will need to recheck the calculation with the pressure values. 34MPa (over 4000 PSI) appears to high. I do not think there is fuel system with that high of a pressure. If my calculations is wrong, I will fix this on the next release.
Actual is the Fuel Rail current pressure that should meet the specified Target value.
Baro value might be coming from pressure sensor built inside your ECM.
My understanding the X-Trail has a 2184 CC (2.2L) engine with : Bore 86.0MM Stoke 94.0MM Max Power 114 HP (81KW) @ 4000 RPM
The 2001 - 2003 spec for the X-Trail remained unchanged until the spring of 2003 when the engine was changed from DTi or DDTi to ETi for about 6 months, it still used a pump as opposed to commor rail, which appears around October 2003 in the UK. I think the pump it is listed for DENSO HP2 16700-8H801. My engine is the ETi but it is no different to the DTi apart from the pump I think.
The ECM does give a barometric pressure reading I checked in the electronic service manual, actual data is only shown on Consult II software, does show a page with listed items, see attached .xps. It is from the 2001-2003 YD section on Trouble codes in the ESM.
If you do not have a copy of the ESM you can down load it easily enough This has loads of information, of course if you have access to a Consult II.....
I hope this clarifies some of the spec for you. Look forward to your getting more out of the ECU. As I said previously, to get what you have is a good job, to my knowledge not even Ian Hawkins Torque has managed to.
Hopefully where ever you are you will have a good Christmas, if I do not speak to you before. Here in the south of the UK very mild and wet conditions, not at all seasonal...
