Opensource LS Flashing(It's Closer Than You Think)

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

i'm just learning about this stuff (quickly) but for trying out these new free flash tools, right now probably got two options..

obdlink (bout $50 buy it on amazon) works with everything, not the fastest thing ever
avt852 (bout $300) fastest most reliable and overpriced thing ever, hard to get i think

i've heard a pretty reliable rumor something really nice might be coming out soon in the price range of an obdlink. if you're not in a huge rush and like to gamble maybe wait and see if that happens. the guy working on it is so stubborn that its unlikely it wont happen, just not sure of timing.

That's a great summary of where we're at right now.

I've got a prototype of the rumored interface and it works great. I'm sure it's going to be the best option when it becomes available. I don't think there's an ETA for that, though. Last I heard, the guys behind it were still refining the design and working out how to get them produced in volume.

If you have a car you want to tune now, I'd say get the ObdLink and go for it. It works fine, you'll just get faster flashes if you buy the new interface later.

I'm not sure about the Tactrix, but if you have one, give it a try. They definitely support the J2534 standard, so the app should be able to talk to the device, but I don't know whether they support the VPW standard, so the device may or may not be able to talk to the PCM. Easy to test though - if "read properties" works, try a test write, and if that goes smoothly, you're good. I've been meaning to try it myself, but I don't know where mine is.

I'll give the Tractix a try, need to build a bench harness first. If that doesn't work I'm in no hurry and will wait.

Thanks Guys

I am going to work towards trying this. My computer that I use for tuning doesn’t have Bluetooth. I see there are several OBDLink units available. I see one that is OBDLink USB. Just to make sure, that one will work, right?

The OBDLink SX is USB-only, and it is supported.

You might also consider getting the LX and a USB bluetooth adapter. I haven't tried that myself, but it should work just as well, and there are a bunch of adapters on Amazon for $10-$15 shipped.

All features work with all interfaces, the only difference is speed. This table is overdue for a refresh, but it gives you a rough idea of what to expect:

The "DVI" row of that table is the one that's still being developed.

I have an SX cable and it takes me right at 50 minutes to read an 0411, haven't tried a full flash yet. I wished I knew how to make my TECH 2 work with it as that would flash ALOT faster.
