Now that the Allpro device is no longer available, what's the best device out there? OBDiag.net no longer sells that tool, apparently.

Any plans for a laptop-based app?

How's this going? Haven't heard from you in a while, Pete!

On the blue/clear PCM-when I say the hardware is very similar-I mean it's *VERY* similar. It's used with the LS4 V8, as well as most all the 60*v6's and the shortstar V6's, so as you say-might need a...

Right now there are some pretty complete XDF's for the 512K PCMs, as you really only want to use the 2002 unified OS for most swaps. The unified OS lets you easily swap blocks to get the...

How's the UI stuff going? Is the hardware abstraction layer stuff working out well? Which interfaces did you ultimately stick with so far?

Nice. Does this mean you're using your own open-source flash kernel now or are you still using the LS1Flash closed-source kernel?

In Arduino, library usage itself imparts zero penalties, it's all tied together during linking. Using functions like digitalRead/digitalWrite incurs penalties because they do a lot more than just...

The PCM on my bench is not a Blackbox PCM, it's an 0411 from a 2002 S10 blazer. It'll talk in 4x mode fine, as long as you keep poking it over and over and over again...it just doesn't say much. In...

something in the way chrome handles links to IMGUR. Ever since photobucket decided to screw their users I switched.

It's still there, Mike.

Pete, nothing in the schematic I posted has been obsolete or will be anytime soon. The part that my schematic replaces that is MUCH simpler, (the dedicated transceiver...

So you're changing ships and going to the PIC from the AVR that you're currently using? The above drawing is just the arduino board plus the simplified 1x/4x VPW level shifter circuit. As I said...

Now I've done it...

The boss is not gonna be happy, I have been picking at this for over 24 hours now, grabbed some fairly basic VPW code for Arduino off of Github and have been re-writing it as a...

4x mode has no rounding of the waveform and as far as I can tell, the pulse width windows are just divided by 4 to push the data rate up-the rest of the spec is the same.

I have yet to purchase a...

Ok, so this is the surface mount, but still 100% all parts available nothing hard to find VPW transceiver hardware. Just checked it, this works in both 1x and 4x modes and if you just use the VPW...

Yes and no. You won't get reliable data transfer with 5v logic highs-and you're going to be receiving 8V coming back at you which will destroy the arduino very quickly. You can make it work on a...

None of the J1850 transceiver chips are in production or are available from distributors anymore. You can't buy them except through second-sourcing and counterfeits. They are *available* but it's hit...

The problem with things like oshpark and seeeedstudio is cost. You can't buy just 1 board through those guys, and oshpark is 3 boards for close to 100 bucks all told.

You can't buy a lot of the...

Can you use raw binary data instead of the AVT data interface? To be clearer, are you attempting to emulate the AVT852-E and are looking for less costly hardware, or are you willing to work with a...

So you're keeping this under wraps...just like every other LS1 flash tool that has been done so far, except Dimented24x7's, it's all "free" until it's complete and works...then it's for sale.
...

Having built a few interfaces for similar things, this is no small feat. When are you planning to update us on the hardware needed to help with the software development? (I'm pretty good with...
