Old post here but I search and read a lot! for those of you still active on the site, I want to confirm something on the ScanGuage!

I'm on 285's now, going to 315's and the 285's didn't change speedo that bad, I'm expecting the 35's to throw it way off. Does the ScanGuage actually work to recalibrate the speedo? I have read mixed reporting, and if it does the change, does it reflect on the "lie-o-meter" on the console for average mpg, or just the speedo it'self?

If it works for the speedo that's enough for me to buy it, but the possibility to monitor AF and Trans are just icing on the cake for me.

Please let me know!


Thanks in advance!

Also, if this doesn't correct the stock guage and trip meter, would you all recommend the speedohealer 4 wire mod of the yellow box? They perform the function correct?

My understanding is the Scangauge just reads the signal from the OBD2 port. You can adjust that signal as displayed on the Scangauge itself by increasing or decreasing that by a %. I think mine is 7% to correct for my 275/70R17 tires. The dash gauges and speedo remain unchanged.

I believe the Speedheeler from what I read does change the signal so the speedo can be adjusted to display the correct speed. I don't recall if the mpg display is also changed.

Scangauge II does not re-calibrate the speedometer.
With 315/70-R17 (35s) I have 15% under speed indication, meaning having 100 km/h on the speedometer actually measuring 115 km/h on the GPS.

Thanks did a lot more research after this and for what I'm wanting need the speedohealer v4 universal and will go that route soon. Since I was SR5 I had 265/65's stock and the 3.73's, when putting the change in the gear calculator in tacomaworld I'll be around 15mph off at 70! So my mods will slow for a bit, a lot of metal cutting, and beating to get fitment without rub at stuff, welding for steering stops, and the speedohealer will be the next item ourchased

These are codes I've tested as working on my truck, your results may vary.

Working codes (firmware 4.06)

Atmospheric Pressure (Psi) - shows to the nearest PSI (may be mutually exclusive of the Altitude reading, i.e. you can only display either Psi or Alt at one time)
TXD: 07E02133
RXF: 04610533
RXD: 2808
MTH: 000A00450000
NAM: Psi

Altitude Gauge (Feet) - Very rough elevation based off atmospheric pressure, shows approx. elevation at set 274' intervals (may be mutually exclusive of the Psi reading)
TXD: 07E02133
RXF: 04610533
RXD: 2808
MTH: FEEE00016B08
NAM: Alt

Horsepower - brake horse power rough calculation based on engine size and operating parameters
TXD: 00
RXF: 400080000000
RXD: 0000
MTH: 000A00170000
NAM: HPR

Transmission temperature
TXD: 07E021D9
RXF: 032180000000
RXD: 2810
MTH: 00070064FE70
NAM: TFT

Distance to empty (a built-in feature accessible elsewhere in the unit, but nice to display as a Xgauge)
TXD: 44
RXF: 800000000000
RXD: 0000
MTH: 000000000000
NAM: DtE

Codes that DO NOT work

- All transmission temp. listings in the Xgauge pdf (Ford PWM, Ford CAN, GM VPW, GM CANSF, VW ISO)

- Tranny temp reported to work for 3rd gen 4Runners: TXD: 686AF101B4, RXF: 044105B40000, RXD: 2808, MTH: 00090005FFD8, NAM: TFT

- A/F ratio: TXD: 07E02144, RXF: 04614544, RXD: 2808, MTH: 05BE00800000, NAM: A/F

- A/F ratio: TXD: 07E02144, RXF: 04614544, RXD: 2808, MTH: 006400800000, NAM: AFL
Transmission temp for my '03, as stated previously but wanted to add to this list for future ref:

TXD: 686AF101B4 RXF: 044105B40000 RXD: 2808 MTH: 00090005FFD8
