Is there a way to get all integrator values across all cells in one shot? Right now I am just looking at the datalog and using the last INT value for each RPM / MAT range. I have to drive around for 10 minutes to get an idea of what my VE table looks like. It would save me so much grief to be able to just dump all of it at once.

I think if you tell the ECU to do MODE 2, you can selectively dump some area of memory. Is it a matter of finding the table offset in the bin definition file and dumping it via MODE 2? I'll check this out as soon as I can get to my car (tomorrow hopefully), but meanwhile, does this make sense to anyone?

I am using AUJP on the 730 ECU by the way.

 

Looking over the documentation, it seems the BMLs are stored in RAM and not inside the BIN. Makes sense, that's why you lose them when power goes out. So then does anyone know where in RAM the BLM values are stored for a 730?

 

http://www.diy-efi.org/gmecm/ecm_info/p4_registers.html points out that there are only 256 battery backed locations, from 0000 to 00FF. The anht_hac.pdf file points out that BLM table starts at 001B, at least for the 727 ECU. Getting warmer

 

Memory locations for $8D BLM
L001B to L002A are BLM cells
Integrator changes each time you enter or exit a cell, that value is not stored in correlation to each of the BLM values.
It is at $00EB if you want the current value.

You are correct, these are all memory location and are not part of the bin.

 

Neat! Incidentally, is has anyone ever made a list of what is stored in all locations between L0000 and L00FF? What other interesting things does the computer remember?

 

The ECM remembers very little at key-off. With the $8D code there are two SAM cells, a few IAC parameters and the stored malfunction codes.

Check out the AUJP_JP2.zip on Moates file area.
The hac has as many memory location identified as I could find.
The source code is relocatable and will compile to runable form if your into making changes.

Unser Source code and hacs.

Might as well grab the S_AUJP V4 and the docs to go with it while your there as well.

Neat x2!! And there's the memory map, in AUJP_JP2.zip! Thank you so much for this!
