Bare board as viewed through the sweet magnifier light on my workbench.

Soldering the two SMT chips on the back of the board is the most difficult part.

Mostly assembled.

I'm three components from being done, will finish tomorrow.  I'll have some pics of how I modified the case for the LEDs to poke through, etc.  I'm pretty excited.   O0

it allows you to read all of the ECU's sensors from a laptop, correct?

If this is true, I'm gonna be picking one of these up.  There are a few parameters I want to be able to check up on, occasionally, but don't want to buy a shit ton of gauges.

Its too bad the OBD2 honda ecu's are so locked down tuning-wise

What software is used?

*edit* maybe I should try clicking the link first next time. :mexi:

Is this any use to OBD1? If not, worthless.

Verify it works correctly, and logs at an acceptable sample rate.  Also, that it works with Binary Editor which is primarily for Fords but can be tweaked to support some other vehicles if they accept an Ostrich.

She's up and working with four different generic OBD2 scanners.  I have to reinstall BE before I can verify it works with that, too.

Mediochre - with the freeware software I've tried so far.  I think the polling rate of the software sucks, a 38400 baud datastream should be able to relate more.

Title: Re: Inexpensive USB ELM327 DIY kit
Post by: Joseph Davis on November 30, 2009, 09:51:46 AM

I'm going to say no.  The freeware Ross-tech 409.whatsis is designed for a "dumb" cable, basically just a USB-TTL or USB-serial cable, and their later offerings have some "intelligent" circuitry inside.  As does this scantool... the scantool is set up to emulate an ELM327 scanner so it accepts ELM327-targeted commands from a laptop/PC... dollars to doughnuts that the proprietary Ross-tech VAG-Com stuff communicates in it's own speshul format.

You keep asking all these VW questions, and it's obvious you want back into the scene.  Why don't you sweet talk Loki out of one of his Scirroccos, or beat up Chuck for his Rabbit?  After paying diesel prices I'm sure you'd find a simple early watercooled project cheap, easy, and fun.  Plus we'd all like to see pics.

Those are easy to reflash; in the euro scene those are the cheap Hondas found everywhere.  Interested?

Always. In fact it is getting a reflash, and some sticks, and do the egr delete at Christmas. My buddy Mark owns http://dieselinside.com/ (http://dieselinside.com/)

Does the tactrix cable work?

Not directly with existing software, but it is set up to be able to mimick most any serial data stream you can imagine traversing an OBD2 port.  It'd require some programming, but can be supported.

Yeah I was gonna say, it seems all the new stuff (mk5-) any CU lockouts are done in firmware, not the k-line restriction we were discussing on the mk4s and audis.

Working on a mk5 TDI right now.  Fucking thing hauls ass for what it is.

Yes.  Id say they are about back to the reliability scale as the digifant cars. Not too much goes wrong, but the shit that does is always weird.

Hmm JD will this work for a 97 chevy blazer by chance with tuner pro? trying to tune my daily on the cheap.

if not will the tactrix work (gotta buy 1 eventually :noel:)

Post by: Joseph Davis on November 30, 2009, 02:32:25 PM
I'll try to have an answer for you by the end of the day as I have ScanXL-ELM and PCMScan installed on my laptop, and I can compare sample rates with the "better" software.

Tactrix 2.0 is supported by Binary Editor, but I don't have one so no comment on sample rate.  EECtuning.org is a great place to ask, IMO.

The Innovate gear claims 12 samples/sec on up to 16 simultaneous channels.  That's fast enough to tune off of.  I have an LM-2 coming to verify that claim with, although I do not doubt it.

Care to share any .xdf's you have for OBD2 GM stuff?
