bHP Gauge
TXD: 00
RXF: 400080000000
RXD: 0000
MTH: 000A00170000 - for petrol car
MTH: 000A00240000 - for diesel car

Confirmed working - bHP

MAF Gauge
TXD: 686AF10110
RXF: 044145100000
RXD: 2810
MTH: 000100010000

Confirmed working - displayed in g/s

Km/h Gauge
TXD: 686AF1010D
RXF: 0441050D0000
RXD: 2808
MTH: 000100010000

Confirmed working - if you want kilometers per hour displayed with the scangauge set to Miles. Useful for me anyway as speedo is in miles but speed limit here here is in km/h
To take into account any speed calibrations made (-2 seems to be a common setting for the Leons) the MTH function becomes
for -3%=> MTH: 006100640000
for -4%=> MTH: 006000640000
for -2%=> MTH: 006200640000
for -1%=> MTH: 006300640000

m/s Gauge
TXD: 686AF1010D
RXF: 0441050D0000
RXD: 2808
MTH: 001400480000

Works but MTH formating of decimal point in the codes needs sorting, will correct it soon
Calibration factor cannot be taken into account in the calculations

ft/s Gauge
TXD: 686AF1010D
RXF: 0441050D0000
RXD: 2808
MTH: 03BC04190000

Works but MTH formating of decimal point in the codes needs sorting, will correct it soon
Calibration factor cannot be taken into account in the calculations

Km/H - m/s - ft/s -> you cannot display more than one of these at the same time in the gauge function

Set Tank average MPG as a gauge
TXD: 04
RXF: 800000000000
RXD: 0000
MTH: 000000000000

Confirmed working - see manual for more options on this

bHP reading hit 224 for me today. Pretty damn happy with that.
Km/h seems +1 or 2 Km/H above climate control reading. Will verify which is the exact with a sat nav later.

Boost - MAP
TXD: 686AF1010B
RXF: 0441850B0000
RXD: 2808
MTH: 00910064FF71

Confirmed to work on Diesels only - measured in PSI. Does not work on Petrol cars as they do not utilise the MAP sensor PID
When get working set FF71 to 0000. Note reading at idle. take that and get it converted to 2s compliment then change the FF71 to this.


Transmission Temperature
TXD: 686AF10105
RXF: 031A04410505
RXD: 2808
MTH: 00090005FFD8 - to display in Fahrenheit
MTH: 000100010000 - to display in Celcius

Confirmed working

Coolant Temperature
TXD: 686AF10105
RXF: 031004410505
RXD: 2808
MTH: 00090005FFD8 - to display in Fahrenheit
MTH: 000100010000 - to display in Celcius

Confirmed working


Am gonna work on getting Boost working.
Also to get Torque displaying

Hi,

Loosely related, but the full set of codes you can get on your climate control are at:

[jonathanp]

cool, already got the BHP one but been looking for a MAP one for while, will have to have a go at setting it this week. Might need a little help though as instructions are a little bit confusing

BTW what do you think off the accuracy of the BHP gauge? I've had mine showing 293bhp pretty consistently but I know my car is nowhere near that, 270bhp tops I would of thought.

although it proved useful the other day as the car has been feeling slow/held back since a cambelt service and other bits, this is somewhat reflected by the scanguage now showing 260bhp

Not correct for Seat
These are
http://lee69.co.uk/Car stuff/Leon/codes.txt

But have no relation to the Scangauge coding

 

[andy15star]

Hi,

On Lee's codes, it says "see chart below" (see number 1 for example), but there's no chart there, is there a link to the table it refers to ?

Regards,
Andy

 

[LEE69]

I think i originally got them from here
http://audi.service-bg.com/Articles/usermanuals/Audi-A4_A6_A8/Clima Control Codes.pdf

 

[andy15star]

Cheers Lee ! - yep, it's there !

Thanks for the info.

My standard 180 bhp cupra just recorded 230 bhp. That can never be right. How does it measure the bhp?

 

[LEE69]

Mines getting the same reading (ish) 219 for bhp either it's been mapped before (and i wasn't told) or the gauge is telling porkies.

 

[xd-data-ii]

Or your MAF is not reading correctly

 

[LEE69]

I'll add the MAF code then mate and see what i get, what do you get?

 

[xd-data-ii]

2.25g/s and 3.6bhp when idle.
Havent really tried reading the max maf reading as well as the bhp reading when flooring it. Will take a look.

 

[LEE69]

Yeah it doesn't store the max does it (not fully looked at it tbh )

 

[andy15star]

Hi, Just a theoretical query really. If (when set to imperial) the ScanGauge can do km/h with Km/h Gauge
TXD: 686AF1010D
RXF: 0441050D0000
RXD: 2808
MTH: 000100010000

Then how could i get it to read metres/sec ? (or for that matter feet/sec) ??

I know there needs to be something done to the MTH settings, but i'm not sure how the MTH coding works. I could probably work it out for myself if i knew what binary to stick in the MTH line of the ScanGauge.

Best Regards
Andrew

That's the readings i get too.

 

[xd-data-ii]

Yeah i plan to look like Im doing work this morning whilst trying to figure out how to work out 2s complement etc for the MTHs function as realised yesterday for the km/h reading it is not taking into account the calibrated speed setting ie. the -3 used.

Anyway, for the MTH 000100010000
0001 (<-Multiply by) 0001 (<-divide by) 0000 (<-add/subtract)

So Im guessing to adjust the km/h reading to a -3 setting
MTH: 00010001FFFD


Will look more into the other conversion later

 

[andy15star]

Hi, please forgive my ignorance here!. I was trying to work out how to set up a gauge for speed in metres/sec (or feet/sec).

I understand that the MAF line needs to be set correctly. Working on xdata's figures "Convert Celsius reading to Fahrenheit is 00090005FFD8", i get the 0009 bit (multiply by 9), i get the 0005 bit (divide by 5), but i don't get the FFD8 bit ?. How does FFD8 equal -32 ?. Are these figures Hex figures ?. Converting FFD8 to decimal, i get 65496 !

Again, please xcuse my ignorance !

i meant "MTH" line of course ! - Sorry !
