I think that's just OBD, then there is an ISO for CAN... J2534 is for reflash. Different standards for different things.

 

ah, okay.

 

Hrmm that openport product from tactrix looks very interesting. I sent them an email to see if they have heard of any compatability issues with the RX8. Gunna have to look around if there is a schematic around to see what the hardware entails, would be nice if I could incorporate it in my device. Looks like they are part of the openECU group so maybe there is something laying around

 

FYI here is a list of currently supported PIDs ... if I missed an important one let me know

#define ENGINE_COOLANT_TEMP 0x05
#define ENGINE_RPM 0x0C
#define VEHICLE_SPEED 0x0D
#define IAT 0x0F
#define MAF_SENSOR 0x10
#define O2_VOLTAGE 0x15
#define THROTTLE 0x11
#define WB_AFR 0x34
#define OL_AFR 0x44
#define LOAD 0x43
#define AMBIENT_TEMP 0x46
#define CAT_TEMP 0x3C
#define STFT 0x06
#define LTFT 0x07
#define RUNTIME 0x1F
#define FUELLEVEL 0x2F
#define INTAKE_PRESS 0x33
#define CYL_ADVANCE 0x0E
#define CONTROL_MODULE 0x42
#define FUEL_PRESS 0x23

 

I'm not sure what half this means. I know it's for the S2, but good work nonetheless Paimon.

 

Hrmm ... for some reason I can't get my AFR reading, neither commanded nor the actual. Not sure if anyone knows, but I am using pids 0x34 and 0x44.

 

Anyone have a list of the extended Mazda OBD2 Pids ? Namely the pids to see if cruise control is enabled and if +/- was pressed?

 

I have a list of pids, but it doesnt show either of those.

 

do you have the standard pids or the expanded set? They arent listed on the standard pids list, but they should be available on the extended list

Check out # 1298 on the Licensed list.

 

Ah, must be the standard list. I guess I'll need to get my hands on the extended list.

 

Yea same here, except I cant for the life of me find anything. I am tempted to just use the 24h serivce document subscription to see if they list it in there, but I dont know if they publicise that information. Places like dashdaq and such offer "enhanced mazda" lists for their hardware, but again, nothing out in the open

 

Ok I am looking at the mazda service highlights for the 2009+, there are some great things we can monitor if only I can get the addresses for them. The document to this point has only given alias names. Maybe someone has access to what the actual pid value is? ASH8?

EQ_RAT1 - Lambda
EQ_RAT11_DS - Desired equivalence ratio (lambda)

MOP_DRV_C - Electromagnetic metering oil pump center driving signal On/Off
MOP_DRV_S - Electromagnetic metering oil pump side driving signal On/Off
MOP_FL_C - Electromagnetic metering oil pump center request flow volume cc/h
MOP_FL_S - Electromagnetic metering oil pump side request flow volume cc/h
MOP_P_ACT - Electromagnetic metering oil pump system pressure actual Pa
MOP_P_DSD - Electromagnetic metering oil pump system pressure desired Pa

[HERES WHAT I AM LOOKING FOR BTW]
SC_SET - Cruise indicator light control signal in PCM On/Off
SCCS - Input voltage from cruise control switch V

 

Maybe they work like this?

Yea I am pretty sure thats how mazda has it, but knowing the module's address is the hard part ... any ideas on who i can contact for that stuff? Looks like all of the DashDAQ and ScanXL etc people have an addon for their software, but its paid stuff.

 

I'm afraid that everyone who has the extended pids isn't sharing.

 

I'll do some digging at work. You say scanxl has an addon? You know the name by chance?

 

Maybe?

Ooo where did you get this??? I will go try it out

 

Bluetooth logging has been added

hardware




Sorry the video is absolutely terrible, not sure why it came out like this. I will try and get some better video

you have the video set to private

 

Fixed, thanks

 

impressive work so far

 

thanks sir I appreciate it.

 

Some Bluetooth Debugging Shots







A new mode added to sniff the canbus


Clicking the joystick allows you to enter a masking for the canbus, here we are just listening to messages from address 650 which is the cruise control light


You can see the changes in the message when i turn CC on and off

 

I hate you.
That is all
Hahahaha.

Really though, that is awesome.
