LS1 Flash Tool Released

So the cable connects to the laptop via serial???!

Still haven't had a chance to try the software but thinking about cables and cost.

Here is a link to pictures of a VPW programming cable:

This is rumored to be the same cable:

No, USB. And they also have AD port for WB. That post about serial was off topic.

Can VATS be disabled/VIN# changed with this software?

Antus, I am sure with christmas coming up your even more busy like the rest of us are, but I am going to ask anyway. Any updates on the flash version of the software?

[antus]

@babywag: you can change vin, but not vats until it can write a calibration.

@mecanicman: Sorry no updates.

Will donations help move project along? I would hate to buy an AVT cable and have the project die out.

I bought a 99 sierra yesterday and picked up my avt cable today. Decided the sierra would be by first victom to try the ls1 flash tool on. I was able to connect and identify pcm no problem, showed me vin, pcm id, ect. I then tried to read the bin. Got some errors and turn my check engine light on and truck would not start. Hooked up with hpt and connected and check engine light went away and it started. Tried this a couple times with same results. This was with version 1.05. I tried version 1.04 and it crashed and gave me log when I tried. I then hooked up and read the bin out with hpt without issue. I am running windows 7, is it my pc or something wrong with cable. Anyone else use windows 7 and have any issues?

Antus, I have screen shot of what ls1 flash says when it fails and the crash log if you want them.
