Top work. I dont suppose it just writes out the box too?
The file format looks a bit different to what we've seen before, including the signatures. Still has a param block at 0x6000.

Meanwhile if you add at end of script

Still on unreleased beta version
That will parse VPW mode23, Ram and Rom to a bin file
Awesome ...
One file for both, or can that be added after each, ROM and RAM thus two files in that script ??
Does ? symbolize a filename (do you replace ? with filename) ??
I did think about trying to write, then I slapped myself to wake up to all the open cans of worms I am already in ... I do suspect it's very possible to write with a little work.
Maybe I should get to it now, the P04 is digging my grave!
-Enjoy

Nice work, I haven't seen the vehicle I originally wanted it to read after I mucked around with throttle body & suggested replacing it.

i found the MAF table its split Low and High i used a GM scale factor and looked reasonable on the data. I also found the dtcs which are like some of the Big truck Isuzu stuff ive seen as in not in order. The dtc right next the the hex code. I didnt go though and convert the whole hex to SAE but you get the idea.. found this stuff in Winols and exported to an xdf
