Re: Memory dump of ECU

I'm going to go ahead and post it today. I just started a thread for it here: http://www.subaru-svx.net/forum/showthread.php?p=677628

Re: Memory dump of ECU

I came across this recently. Looks like late 1980's vintage. Probably the diagnostic tool for the old L-series cars. I haven't tried it on my car yet, but it looks like it just reads and writes byte values by address over SSM0 or SSM1 protocol. It probably came with a list of important addresses.

Cool Re: Memory dump of ECU

On a separate note. A member here emailed me some evidence that Subaru knew about "the 92 problem" and supplied an adapter along with the SSM2 to clean up the signal. Have a look at these pictures:

THAT THING should be in a museum!!! A meter to display a HEX value? Wow!

On a related note, I think I have the final versions of the definitions files for Evoscan and JECScan for you to host on your site. I have done some work on the FreeSSM files as well but that software wants all of the switch stuff and trouble code stuff as well and I have made bascially no progress on those. Still, the development version of FreeSSM can use what I have to pull ECU and TCU data from the OBD2 cars.

Re: Memory dump of ECU

It's not of any importance but I just read a Canadian TSB ROM. Despite having a hand written label it is identical to the US TSB ROM which is also identical to the image on your website labled as a 93 SVX image with the ROM ID 722527 (i diffed them all to be sure).

Re: Memory dump of ECU

Thread resurrection! I ordered all the parts to make the daughter board with the two chips and get ready for tuning. I started playing with tuner pro and rom raider tonight but cannot get the definition file to load into either program.

Would love some help and will document anything I find when I get around to actually poking its brain.

The trick is to get the file to the right size.

The address space of the chip is 64K from 0x0000 to 0xFFFF. The ROM is 32K and stored at address 0x8000 to 0xFFFF. I normally download the 32K ROM and then add 32K of blank data in front of it to make a 64K file so that the file offset of the maps lines up with their address in memory.

Have a look at your tuner pro and rom raider definitions and see whether it is expecting a 32K or 64K file.

Re: Memory dump of ECU

Am I editing the rom or the config/definitions? In RomRaider it tells me no definition file found.
