DashCommand - An Alternative to Scangauge

damn...thanks [MENTION=70922]Robb235[/MENTION]

That was the main reason for buying. I wonder if someone has developed a formula I can put in and come up with an 'estimate'. I know there's some brilliant folks out there that can probably develop some formula.

I have been using this now for like a week and one thing I'm surprised by is that it can read vacuum pressure and boost. I didn't think our trucks would read that from the ecu but it seems to be pretty accurate. It reads around -10psi for vacuum which is 20" hg which is around where it should be and goes up to around 6-7psi in boost which is around where it should be with a supercharger.

Can you post a screen shot of it showing vacuum and boost? I didn't think our trucks had the ability to monitor or report this. I mean, without a MAP sensor, how is it extracting this information?

That's what's I was thinking. I'm surprised by it too. I'll post a screenshot when I get a chance. I wish I had a regular boost gauge to compare to see how accurate it is.

Does Dash Command give you any way of "seeing" the formula that it's using for that particular PID? Like PID number and formula, similar to the picture below?

I installed this a few weeks back and it looks very informative. After a few days I stopped using it because it was killing the battery life on my iPhone.

I will continue to follow this thread to see the benefits and better ways to configure it.

Please keep posting the things you learn about this.

There are numerous apps compatible with the elm327 wireless emitter. I believe some are even free! This app is just the one that has the best all around reviews and support, and for $10, who can argue?




Exactly! I considered using my old IPhone as a permanent type thing, but I didn't want to leave it attached to my window at all times for fear of someone breaking in, so I just decided to use my phone. But if you do, we need pictures!!!

Did a little more searching on this. The ELM 327 wireless OBD2 will work on Androids. Here is a link for the ELM 327 that is bluetooth and it is $8.40. About half way down on the right there is a review that says "So cheap yet does what you'd expected it to do. Running it with Torque on my Android device and displays seems accurate". You're saving some money with this over the OP's original link.

I was also looking into the scan gauge and still might go that route for the convenience of it. Not really sure about how fast running this app will drain your phone? That would be my main concern, and where you'd mount your phone at. This is great information, and is well worth the investment of a little under $14.

Great write up too!

Great call! This is what I bought: Advanced ELM327 v1.5 Bluetooth Interface OBD2 Scanner Adapter TORQUE ANDROID
poleclimber63-albums-misc.+stuff-picture26608-obd2.jpg

I grabbed my sons' old Samsung Android phone, downloaded Torque and it works great! As I've just downloaded the free version it doesn't have all the features as above, but it does have the key ones. The phone isn't activated so I have no GPS linked info. I do have a Blackberry and Torque is available for it, so I may try it. I will get used to using this, and if I develop a need to use some of the other features I may spend the $10 for the app. Still, I'm blown away by how much info is available with the $13 I spent!!
As for power, I have a car charger when the bat is low, and the phone still functions while charging.

Thanks for the review!!!

Dash Command doesn't (to my knowledge) have a transmission temp reader. So on my iPhone I used Engine Link, then used [MENTION=70922]Robb235[/MENTION]'s instructions from his thread (link below) to set up the trans temp.

http://www.amazon.com/Wirless-Diagn...der+Scanner+Scan+Tool+for+Iphone+iPad+iOS+PCl

I ultimately decided to switch to a scangauge, but listed below are a few pros and cons I experienced with the iOS setup.



Pros:

1. Awesome display, including graphing out fuel economy and giving you much more than the standard four at a time of a scangauge.

2. If used with an old iphone and you also download an offline maps app (motionx, gaia, galileo, etc), you have a gps and scangauge in one unit.

3. No wires to route and zip tie to anything during setup. Granted, I didn't do this with my scangauge, but I know a lot of people prefer a cleaner install and I'll probably have to at some point as I'm sure that pesky cable will get on my nerves eventually.

4. An app like Engine Link has a "mirror" option for setting the device on your dash, which will then project a reflection onto your windshield, giving you a sort of poor man's heads up display. Not sure if it's a huge feature, but a cool little trick.

5. Easily removable to put into another person's rig and check on anything if you need/want to. If you unplug a scangauge, it resets itself and constantly setting up the trans temp can be a little bit of a pain.



Cons:

1. You have to reconnect the device to the obd dongle every time you start the truck. This can get very annoying and lead to me often just leaving my truck on while stopping on the trail, which I'm not a fan of doing.

2. I also experienced connection issues. Sometimes, when on a trail for an extended period of time, I noticed that it would still say I was going 20mph when stopped, or that my transmission was only around 180° when I had just been climbing rocks (I've mentioned in at least one other thread that my tranny gets pretty hot because I don't feel the 70264 was big enough to fight the AZ heat). This was due to the connection sometimes dropping out on the dongle and I would need to reconnect it to get accurate readings again.

3. The screen on an iPhone, iPad, etc. is very glossy. If the light hits it just right, you get a pretty pronounced glare and I wasn't the biggest fan of this. Granted, you could easily buy a matte-finish screen protector, but I never did because I was too lazy to do so. Someone with more initiative than myself could definitely rectify this minor problem.

4. Consider getting your device a lifeproof case or something similar if you're going to use it while out on the trail. Here in the desert, things get pretty dusty, but I would imagine in other regions you could have issues with mud, water, etc.



So your mileage can definitely vary with this, but those were my experiences. I didn't mind the iOS setup, but I wanted something a little more fixed in the truck that turned on every time I turned the truck on without any connection issues because I'm anal about watching temperatures and things like that. I'm sure that once I put in a bigger tranny cooler I won't worry about it as much and I'll watch it less, but I'll cross that road when I come to it.

So to sum up I can get a cheap LyL wifi odb2 reader

http://www.amazon.com/Wirless-Diagn...sr=8-9&keywords=scanner+obdii#customerReviews

and iphone Engine Link software and program formula...

Header:0
ModeAndPID: 01b4
Formula: A*(9/5)-38
Min: 0
Max: 350
Unit: °F
Description: TFT (you can call this whatever you want)

and get transmission temp?

^ Not sure about the Torque app, as I don't have an android, but for DashCommand, yes, it will read ABS codes.

I've tried to do this with DashCommand but no ABS codes popped up. I have the VSC TRAC OFF and ABS lights on. Am I doing something wrong? I have 2002 4Runner.
 
The real value of the Scanguage is that it is always on, doesn't run on a battery and doesn't use Bluetooth.

I've used these type of apps and then I bought a scanguage.

The fuel level sensor doesn't report to the ECM (at least, not that I'm aware of), so that information isn't available via the OBD2 port.

[MENTION=70922]Robb235[/MENTION] should the ECM be receiving fuel flow data on a 2000 T4R? What about horsepower and torque?

I just purchased the Dash Command app and synced it to my Veepeak OBDII adapter and I'm not getting all the data I should be. Engine RPM, speed, timing, AFR, coolant temp, intake temp, fuel trim and load all seem OK, but nothing about fuel consumption, horsepower or torque. Is this data being reported to the ECM or do I have another issue? Any help is appreciated.

I don't think there's a way for the ECM to directly measure fuel flow. There may be a way to indirectly calculate it since the ECM knows how much air is coming in (MAF), and the AFR (wideband O2 sensor on Cali emissions models).

I wish there was a way to measure the injector pulse widths on these Toyotas, but I'm not aware of how to do that.
