I have a slightly different question, so started a new thread instead of hijacking the other one.

I am still looking for software for a ScanTool to measure the stuff we all want; EGT, AFR, Advance, Boost, and some metric like RPM for graphing. I have tried,

ScanTool software - Close, but no logging, and all the data is on different pages.

Digimoto - Not as many params, but easier to use.

ScanMaster - Hard to configure, and not the right data

ODBLogger - No configuration, or real instructions.

wODB - Does everything, perhaps. So complex that I can not figure if it logs what I need or not.

Vehicle Explorer - Can't get it to work with my Elm based ScanTool.

Palmer Performance - Can't tell. Need a beta license.

Am I missing anything? Anyone using the elm based tools and getting all the needed data? And please don't saw I shoulda got a DeltaDash. I have already kicked myself for trying to save money...

I may be biased, but I think the Scanmaster is pretty close. Logging and graphing is handled on the palm (Palm software is included), the EGT is just the stock sensor, but the unit has 2 analog inputs. One for an LM1, and one for a 0-5volt Thermocouple input.

(don't forget the performance timer and Acceleration fuctions too...)

Now, the only 5 volt thermocouple units we could find are kinda pricey, so if there is a demand we will make one that is a straight plug-in......

The WRX Scanmaster is well supported, and any software tweaks we make will be free.

Thought I'd put in my .02

Can you provide any more info on the scanmaster? I've never heard of it.

Looks like there are two "scanmasters." :D I was talking about the Scanmaster at http://www.wgsoft.de/ Is you solution a hardware or software or both? Will it work with the Elm base scan tools? Where is it? (Did a search and found forums only)

I have the digimoto, and I like it and their service/support is great. If you have a suggestion you can email them and they will look into adding it in future versions. All i need is a faster laptop 233mhz old school :)

Delta-Dash

Are any PC2003 compatible?

All the links are for the Mitsubishi version, the Subie version is available for pre-orders now, deliveries will be in a couple weeks (in time for christmas)
There are just a couple differences between the Mitsu and Subie versions, since the Subie version is customized specifically for these cars.

No it wont work with the ELM tools. It takes the place of the ELM stuff.

Actually I downloaded the german "Scanmaster" software a few months
and its not so hot.

Take a look and post back,

TurboBob

Well, since I have the Elm based tool now, I don't really want to spend another $200. This is why I am not getting a delta dash. The information is there, but I just can't get to it yet. I have spent some more time with wODB. Massively robust, but massively complex as well...

wOBD looks cool, I'll have to fiddle with it... I have the ELM stuff laying around somewhere....

The Scanmaster has a much higher data rate by about 10x. For logging/tuning the datarate really helps.

If you read some of the tech info on the wOBD sight, they have several tweaks that can bump the data rate quite a bit. Conservativly you can get 6-8 queries a second. I will have to play with it to see if we can boost it further. I really need someone local to help me bang on it. However, non-local help is always appreciated!

I read those. The ISO spec has a range of allowable delays. I'm not sure if you can tweak them all in wOBD or even if ELM allows tweaking them all. 6-8 items per sec is pretty good for a straight ISO tool.

So tell me bofh, did you get the Elm to sufficiently log the data, and capture what you were after? Give me an update at where your at with this, or did you just break down and get the Scanmaster 3 ? ;)

Still looking. openecu.org shows promise, but it ain't there yet.

I wrote a perl program (running on ActivePerl on a Windows laptop) to use the Elm chip to pull and log data. Works OK, but the problem I run into is that I simply can't get the Elm chip to pull data any faster. I can only draw about 3.5 parameters per second, which is still painfully slow. I probably need to use the Subaru Select Monitor protocol, but... being a proprietary protocol, it's probably out of reach to me.

My 3.5 parameters per second data rate is the best I can get after using a number of "speed-up" techniques on the Elm chip, such as reducing the wait time to as little as possible, using compressed ('packed') data formats, etc.

openecu logger (http://openecu.org/viewtopic.php?t=24&postdays=0&postorder=asc&start=15)

It may not be pretty, but it sure will work. You just need an OBDII -> serial cable. No ELM chip required.

I haven't had a chance to do much with this lately, but porting it to run natively in windows as opposed to cygwin has been on my list. I'm just not familiar enough with Windows to do it (nor have I had the time).

It should get a sample/parameter every 100msecs, for 2-3 parameters. Each parameter you log will slow that down.


Enjoy!

Mike -- that looks very interesting. I checked out the link -- if memory serves, I think I'm looking at C++. Unfortunately I don't have a C compiler on my laptop. Is there an executable (for windows/dos) that I can download from somewhere?

Thanks

I need some help converting it to compile on windows instead of cygwin.

Maybe this weekend (since it's gonna rain :() I'll work on it.


Mike

Actually, from a quick google search, cgywin looks like another "linux in windows" setup (I'm sure with very differnces, etc.) but I'll try just loading cygwin on my laptop.

If I get cygwin on the laptop, how to I compile/execute your code? Sorry for my programming NOOB-ness.

It's alright....I'm glad to see people getting involved with this.

Once you install cygwin, compile with:

g++ -o logger.exe logger.c

That will create an executible you can run under cygwin.

Good luck!


Mike

Mike -- I just loaded cygwin, and compiled your code.

What am I missing? Your program answers me with "No options set for logging, exiting." and quits. Do I need to tweak default variables before compiling? Is there something more to the ./logger commad line I should enter to execute?

Thanks, Scooter

Hmmm...

Try this one:
http://mikeschear.com/SSM/logger_DEVEL3.c

Can you send me a link to the other one that you are compiling? I don't see that message anywhere in this one?

Scooter? have you been able to use mike's program on the ELM?
I have tried several times w/o success.
i read up the ELM chip specs and turns out the baud rate is fixed into the chip

Please let me know if u managed to get it working with mike program

The program won't work with the ELM interface. The ELM interface interprets data between the laptop and the ECU. This is not what you want in this case.

BTW- the original program was written by Visceral over one openecu.org. I just made some modifications to it and have been experimenting with it. Just want to give credit where it's due :)


Mike

I want to encourage the people here to get on openecu.org and help get things rolling. Open source data logging is almost there. Open source tunning tools might be on the horizon!

Bofh -- I'll register later tonight on openecu.org. My programming skills are crude, but my interest in dyi reflashes is high!

For data logging purposes, Autoengenuity isn't bad and it comes with software for rolling chasis dyno.

I may be biased, but I think the Scanmaster is pretty close. Logging and graphing is handled on the palm (Palm software is included), the EGT is just the stock sensor, but the unit has 2 analog inputs. One for an LM1, and one for a 0-5volt Thermocouple input.

(don't forget the performance timer and Acceleration fuctions too...)

Now, the only 5 volt thermocouple units we could find are kinda pricey, so if there is a demand we will make one that is a straight plug-in......

Wondering if Turbo_Bob ever came up with a way to monitor a non-factor EGT sensor with the Scanmaster's external 5 v input.

thanks!

Yes, we have this figured out. I need to update all the software soon to include this.

Bob

Great. When you do, please let us know and also consider stocking or at least pointing us directly to the probe etc. I would like to update my unit as soon as available, as I do not want to have to add another gauge.

thanks again
