I haven't tried them yet. Give me a specific one you are interested in and I will give it a try.

well i imagine we only have bank 1 & 2 for short and long fuel trim
(can you try those four?)

and only bank 1 sensors 1 & 2 for O2.
I wouldn't know how to interpret the O2 data... (some value from 0 to 99 is what afr?)

if that is too many requests, I apologize - I figure those are the ones that apply to our car.

More stuff seems to keep popping up during this holiday week, so i probably won't get to this until next week. Please remind me if I forget!

OK,

I've printed my form - just got to dig up my receipt and bring myself to remove the unit from my car so I can send mine in ^_^ heh....

I really use it to watch my warmup in this cold weather.... 90F/CLSD LP before i'll move the car - unless I really have to do otherwise.

Right now i run with the gauge display - water temp, AIT, open/closed lp and GPH; I don't know if I'll change it to any new items once i get the Xgauge upgrade... (it's too bad they don't make a double display - 8 gauges at once) but it will still be useful for occasional checking~ (that's why i ask about the trims, etc.)

I'm pretty good at watching the warmup tach behavior so I can live without it for a little while i guess.

How well does the mpg display work for you?

secret8gent

I'll assume you're asking about the gauge mode (not trip computer mode):

the instant mpg? it's basically worthless... (a one second snapshot of fuel consumed versus disance traveled is too short a window - it jumps all over)

I suppose once you get the xgauge feature upgrade you could do the current trip mpg as a gauge... that has value. Currently if i'm curious about that i just switch over to the trip view when i get where i'm going...

the other thing that interests me about this upgrade is that the device seems to have been updated for the vacuum fuel cut, mine never goes below .5 gph (if i remember correctly) - with the update i should see 0 gph in vacuum. (if earlier posts are accurate)

mdw1000

Actually I find the instant mpg somewhat useful. Gives me an idea of how driving style affects fuel economy, etc. You can get the same indication with the gph gauge.

secret8gent

i prefer instant gph to mpg specifically because it charts fuel per time rather than fuel per distance.

to me, the consideration of distance traveled obscures the more pure data of fuel consumed @ a rpm/load

traffic flow can have such a significant effect on mpg

mpg only makes sense to me when i consider the ultimate object of car is move from a to b (rather than the objective of the engine which is produce force)

DarkBrew

Why does the fuel flow reading drop to 0 when the ECU switches to open loop??

mdw1000

I'm guessing you are seeing that when it goes into the fuel shutoff mode discussed earlier in the thread.

DarkBrew

I've seen that but...

No. This is happening at highway speed (124 km/h), cruise control, relatively level ground.

EDIT:
Got an answer from Ron Delong at Linear Logic

Look at the TPS at idle. Set the CUTOFF value (MORE>SETUP>FUEL>CUTOFF) to 2 higher than the idle TPS value. For instance, if the idle TPS is 14, set CUTOFF at 16.

If this doesn't help, set CUTOFF to 0. This will turn off the fuel cutoff sensing which is causing your problem.

My cut off was set to TPS=24. Based on Ron's suggestion I set my cutoff to TPS=15.
Fixed the problem.

i entered the hp code and it works great.

in 3-4 weeks i should have my turbo reinstalled on my car, then i'll get to see if it calculates the extra power properly.

mysql101

also i think it would be wise to start a new thread specifically about scangauge xgauge codes. looking through random unrelated scangauge comments is difficult. the hp code is the only one i've made use of so far.

DarkBrew

I've been trying out the X-gauge instruments. The Scan Gauge is a very slick piece of technology.
Did an X-gauge code thread ever get started?

mdw1000

Took me awhile to remember to post this: I did try all the O2 sensor codes. I only got one of them to work, which was I believe bank 1, sensor 2.

secret8gent

thanks for the update~

Hi all,

I have read all the posts in this thread because I am interested in purchasing Scan Guage II. However, I am not sure if all the information provided by the gauge are useful to us.

Ok it is useful to know a fault code but how often you get a cell in your car? If you get it rarely why not check it in dealers?

I would find useful guage an oil temp but our car does not have the sensor.

So what really can I do with water temp, and air intake temp and rpms etc?

And the trip computer , MPH etc I do not care to find out because our car consumes a lot of fuel.

So IS IT REALLY useful?


I guess not. And for those that see very useful scans with laptop in the car I agree but if I do not have a car pc then I do not like the idea of having a laptop inside the car.

DarkBrew

Well the fast changing gauges are not all that useful because of the slower update rate. I like the water temp gauge in the winter because it lets me know when the car is fully warmed up.
The air intake temp is interesting because the inlet temp can get much higher than the ambient sensor as the engine warms up. If I do the throttle body bypass mod I'll be able to gauge the result.
The mileage feature lets me modify my driving style and route selection for the best results overall which will help pay for the unit.
I've already read back a fault code for an O2 sensor. I was able to buy the sensor on Ebay and get it installed at a local rotary shop. The dealer would have charged me roughly three times what I paid for the part and install job. (more than enough to pay for the unit) BTW the dealer charges about one hour labour to check the codes once you're out of warranty.
In summary, get one by the time your three year warranty is over.

secret8gent

exactly.
(this is why i still haven't sent mine in yet.... - well that and I'm lazy/can't find my receipt)

mysql101

coolant temp is available without the update. It should have water, and intake temps.

You also don't need the receipt for the update (unless you've bought yours so recently that you're elegiable for the free update)

DarkBrew

mysql101, where's the scangauge xgauge codes thread??
I've installed all of the code listed in this thread and I've adjusted my cutoff setting (see #111 above) but I'd like to try some more...

secret8gent

haha, i think you misunderstood me!

i do use it currently for the water temp (which i depend on for a safer warm up during these winter months in NE); and i do qualify for the free upgrade.

accurate water temp was probably the most significant gauge item to me out of the box.

I love this guage. Period. I cannot wait to start messing with it.

DarkBrew

^^ So you bought one? Cool.

I got the new one with Xguage as a christmas gift.
