Linear Logic Scangauge Xgauge Programming

[Speedy3]

Has anyone figured out how to program an xgauge for AFR and Knock Retard or Knock Count?

 

[Shagate]

No, and Linear Logic keeps saying new "guage" codes will be coming "soon" -- for the past 6 months. :mad: Looks like its getting time to upgrade to a DashHawk...

 

[Speedy3]

I contacted MazdaUSA to request the "as-built data" for PID data on the AFR and Knock Retard/Counts. I'm still waiting for a response.....

Some codes:

Cat Temperature
Txd:07e0013c
Rxf:0441053c0000
Rxd:28100001000affd8
Nam:cat

For the above:
1st param: 07e0013c
2nd param:0441053c0000
3rd param: 2810
4th param: 0001000affd8
(Works! 3-16-09)

Manifold Air Flow
Txd:686af10110
Rxf:044145100000
Rxd:2810
Mth:000100010000
Nam:maf

Short Term Fuel Trim Bank1 07E00106 044105060000 2808 00C80100FF9C SF1 or STF (Works! 3-16-09)
Long Term Fuel Trim Bank1 07E00107 044105070000 2808 00C80100FF9C LF1 or LTF (Works! 3-16-09)

Horsepower:

TXD=00, RXF=4000800000000, RXD=0000
MTH=000A00170000, NAM=HPR
(Works! 3-16-09)

Boost (MAP-100KPa):
TXD:07E0010B
RXF:0441850B0000
RXD:2808
MTH:000A0001FC18 KPa (Subtracts 100kPa from a mode 01 MAP reading)
NAM: BST

Use this math to get PSI:
MTH: 00910064FF6F psi (Converts to psi) (MAP-14.5psi)
(Works! 3-16-09)

hope can get the ScanGaugeII to display these also:

1) Transmission temperature
2) Oil Pressure
3) 0-100km/h timing

 

[Speedy3]

I am getting some Mazda test codes today from Linear Logic. Stay tuned!

 

[tunersteve]

Did you ever think to check the MSD forum for Dashhawk info. I believe the PIDs are identical, and they have them posted.

Link to forum please. The linear Logic Scan Gauge has a different format I believe. I will check them out though and send them to Linear Logic.

1) is coming soon.

Ok, so far I have gotten:

Knock Retard (KR) (in degrees)
TXD: 07E0221746
RXF: 046285170646
RXD: 3008
MTH: 000700020000

Tire Size (in revolutions/mile)
TXD: 07E02216F0
RXF: 0462051606F0
RXD: 3010
MTH: 000100010000

Barometric Pressure (in PSI)
TXD: 07DF0133
RXF: 04418533
RXD: 2808
MTH: 006400450000

MTH: 0001000A0000

A/F Ratio, transmission fluid temp, and fuel level coming soon.

 

[Cannondale]

No luck on the oil temp or oil pressure read out?

 

[OJ Bartley]

Holy crap, the SGII can read knock now?? I will have to try that this weekend... time to get out my programming book again!


Edit: No luck for me. Just reads 0.0 constantly. I'd still really like to be able to read knock (and fuel pressure, but I don't think that's possible).

 

[dredman]

I know this thread is just over a year old, but I recently got a scan gauge myself and was trying out the codes listed here on my 2005 Mazda 3. The Knock Retard appeared to read zero constantly as OJ Bartley said when I tested it in my garage while idling and revving in neutral, so I never paid it any more attention.

However, I just happened to have my scan gauge displaying it one time when I was going up an incline, and then it started to read varying figures. Some more experimenting while accelerating and while the car was under load on many other occasions confirmed it does in fact work.

So I'm just updating this thread to confirm that the codes work for Knock Retard for anyone else searching through the forums for info on it.

 

[OJ Bartley]

Get the heck outta here... I'll have to try it again and give it more of a chance this time. Thanks dredman, I'm glad you had more patience than I did!

 

[dredman]

LOL - no probs. I think it had more to do with luck than with patience, as I just happened to have it on at that time. Either way, when you try it, make sure the car is under some form of load (accelerating going uphill, with the air condition on, and a full load of passengers, etc.). Hopefully you'll get a reading too

 

[05Mazda3sp23]

so do these codes work for just the mazdaspeed 3 or is it any mazda 3

 

[OJ Bartley]

They should work for any Mazda3. There are a ton of different cars using this little gauge. It's been a long time since I set mine up, but basically, you input the engine parameters yourself (I think) and it will take the data it gets from the OBDII port and output whichever 4 things you want to display.
