Post your ScanGauge setup & Adjust %

[FunkSkunk]

Hey guys, I know there is a bunch of us with Scangauges and thought it would be great if we all pooled together our info and shared our setups. This may help others when calibrating their SG if they have a similar or even the same vehicle. *I know there are variables to every car but this could be a helpful guide. So, for instance what was your fuel usage adjustment for your vehicle and maybe even post up what you like to have up on your SG screen while driving.



**based on the pic, I wonder what car can get 7mpg at 129MPH!!?

[Unforgiven]

Heh, if I get the scangauge, will try and see if I can match those numbers!! NOT lol

[RH77]

Only adjustment:

+10.1% Gallons

A little pessimistic, but it's like setting your clocks ahead 5 minutes so you're not late YMMV

I don't have X-Gauge (yet)...

+8.7% on the Elantra. The real adjustment probably is around 5% but I like to know the number I see is a worst case scenario.

The TDI is just not accurate on the scangauge. I just use it as a relative incidator to see how I'm doing between trips. It would need a different correction factor for each rpm. In fact, it the correction factor could be just a linear equation formula, it would be much more accurate.

Between 5 and 10% on a stock smart cdi diesel, and looks like 10 - 15% on the model 451 gas

A remapped smart diesel needs to be at 30% +/-

2008.5 Mazda3 hatch, 2.3L, 5spd auto...right now correction is +12.1% and it's just about dead-on.

FunkSkunk -

I have a ScanGauge I. I set the engine to 1.9 Liters, the speed to +2% for my tire/odometer calibration, and the tank to 11 gallons.

I don't use the tank-to-tank fuel calibration function because I don't want to do the fill-up-to-the-top and then drive till it's at E or on fumes. I always fill from 1/4 to 3/4 full, which is about 5.5 gallons. For this reason, my day-to-day current MPG is only a *relative* barometer of MPG for me.

Here are my usual instant choices :

TPS IAT
MPG FWT

CarloSW2

[taco]

98 taco
engine 2.7
10.1 % fuel adjustment
+2 speed
cuttoff is set to 0 cause i dont use it idle is 14-15 on tps, 77 wide open. i was getting funky readings.

it is usually.1 pecent off by the most.

camry i am currently doing my first set up with it.

I have my fuel calibration at +5% and it seems to be reasonably accurate. I don't use cutoff (set at 0) because I can't say for sure that my car does this. My TPS reads from 19 at idle to 92 at WOT. Right now my main display shows:
TPS MPG
LOD TRP (that's my abbreviation for trip gas mileage)
The bottom left spot is kind of a wild card. I put the horsepower gauge there often, since it is a good all around indicator of how hard the engine is really working. I just put load back there to experiment with what load when accelerating will produce the best FE. Sometimes I put coolant temp there, like when I am trying to figure out how big a hole I need in my grill block for adequate cooling, since the stock temp gauge is useless for this. Or sometimes I put IAT in there to see how much it deviates from ambient temperature. I have some fun manufacturer specific X-gauges for my Escort too: trans fluid temperature, torque converter slip ratio, fuel pulse width, gear ratio, torque. Mostly curiosities, although knowing what the converter is doing can be helpful.

Any other Metro 1.0L owners want to chime in on this?

My speed offset is easy: 6% because of the transmission swap (the 8 valve SOHC 4-cyl car had smaller diameter wheels/tires).

My problem is I don't drive enough to get a chance to nail down the fuel offset. (Also, I haven't been trying very hard.)

I've had the SG2 set at +8.0% gallons for a while, but my fill today was way off: 7.83 gal actual vs. 8.82 shown on the SG. That's 12.6% high, which suggests I actually need a *negative* offset to be accurate.

Looking back through my log, the actual vs. SG reported gallons seems to vary a fair amount. And I almost always use the same gas pump.
