Post your Scangauge related questions, install pics and share opinions here.

Since i installed mine with X-gauge feature i have few questions for other owners:
1. How accurate are the MPG estimates? Mine are off by about 7mpg even after i calibrated the speed data on dyno (adjsted 2% with stock wheels/tires)
2. Whats up with HP? The max reading i saw was, like 150hp
3. I really expected it to read MAF sensor data (like liters per minute or something like that) because i wanted to experiment with different CAIs to see what makes a difference. So if anyone has a universal pro scanner (Snap-On or similar): can you see the MAF data on that, or is it just not displayed by the ECM period? I have an 06.5 with CAN if that matters.



This is my current set-up. More pics here if interested: Dual Gauge Pod

Excellent thread, Victor!

This one's a sticky for sure!!!

[PCH]

Cool, lets also hear from Gen2 people

[zobispo]

mine say the same too like around 160hp automatic gear in full throttle. kinda weird.

*watching*

here's mine

Very cool, Big Bird, looks like the gauge's light matches your A-pillar ones

I got to play with a Snap-On scanner today and saw few interesting things:
MAF is shown by the ECM as grams-per-second data:



There are other parameters available for viewing, so it should be a matter of obtaining a special code for the Scangauge to display them:
VVT-i data. That can be usefull for those why have a turbo and run VVT-i controller. Also helps to diagnose a fairly common actuator problems:



Misfire:



Air/Fuel Ratio is in the data stream, but does not change quickly. I had it stuck at 1.00 which is ideal 14.7 to 1 Air-to-Fuel ratio, but ECM does not update it is fast as O2 Sensor readings, so it does not seem to be of much use. Injector Pulse Width also shown:

Here is mine where it used to sit I have moved it down and put a A/F gauge & Boost gauge in the cubby.


1. As for accuracy I find it spot on I have the tank set at 11 gallons, engine at 1.5L, and speedo correction at 1% with 205/50/15's speed checked against the TomTom.
Example from the drive today..
110 miles, used 3.28 gallons and averaged 33.7 MPG (3.28 x 33.7 = 110.5)
I usally don't do the fillup > done step but when I used to it was either right on or off by only a tenth.

2. HP comes right from the ECU and is supposed to be at the crank before any drivetrain loss I have done about the same thing and at WOT it does go way up there but the normal crusing numbers seem more realistic.

3. XGauge commands can be user programmed which is what the upgrade they did a while back was for to allow for more commands beyond the basics to be displayed. Here is the how to http://www.scangauge.com/support/pdfs/XGaugeCoding.pdf of course it's not for the average scangaugeii user!

should we have tank set to 12 or 11? since or tank is like 11.9 or something

I have mine set at 11 you are supposed to round up, I thought it was just over 10 did I read the Scion manual wrong or am I thinking of something else?

[Big_Bird]

i prolly read it wrong, I dunno i remember this from when they frist came out in '04 on the east coast. lol it's prolly me

EDIT: just checked, it's 11.9 gallons, I have mine set to 12

[PCH]

What kind of TPS readings are people seing? Mine is 11 closed and 78 fully open.

Just saw in this thread: FS: Scangauge II Xgauges version that MAF readings can be displayed.
I already programmed mine to see the airflow data.
