Question for the Gurus

[robertisaar]

the 87.5 may or may not have been where i found mine....

we need a shifty eyes smiley...

Hmmmm 5.2 is 189Mb in size and I found a 5.5 thats only 87.5Mb.

I will check both out.

[robertisaar]

sometime in 2009.

[Weatheralls Auto]

I will keep searching then, thank you.

(does it have a build date? so I get a reference of when newer once were released? )

[robertisaar]

mine is 5.5.0.925t

[Weatheralls Auto]

How old is version
The IDA PRO Disassembler and Debugger version 5.2

I seen mention of that version of over 2 years ago, not sure how up to date it is?

[robertisaar]

i'm still working on learning it myself, but it is highly recommended.

not cheap IIRC.... but the internet is VERY full of resourceful people...

[Weatheralls Auto]

I have seen IDA mentioned a few places I have been searching, I guess it is a Program I should get?

( I posted elsewhere that I had opened with Hex Workshop and even Olly Debugger lol, but Hex not showing me to much)

[robertisaar]

both things sound right. the OBD1.5 PCM i have torn apart at the moment has these things printed on it:

Intel
16155187
AN28F256A
E 5012AC
U4030107

IDAPro supports the 68330...

[Weatheralls Auto]

Well I took apart 1 Pcm I had here, The Flash chip said
INTEL
16236995
AB28f400BX
U8390438Q

So I assume it is an Intel 28F400BX based Flash Chip?

When I read that it is "motorola 68330 32bit code" that means that Chip is coded with a Code Style named motorola 68330 32bit ?


Sorry, a newb when it comes to this but am learning.

I am sure you have already checked this out, but if not here you go. I have used this version of Hyper terminal on Vista before, and it's free to download for personal use.

that seems familiar for some reason...

thanks for the link, i'll see what i can make of it.

it may be called something different, but on the 94-95 LT1, you use mode 3 commands and then the PCM spits out the entire BIN... i imagine given the correct command, the OBD2 PCMs should do the same. i've been trying to find something like hyperterminal to do it with the 93-95 3100, but can't find anything that wants to work with vista...

really? OBD2 FTMFL!

[Weatheralls Auto]

The Pcms do not have a routine built in to dump file unfortunately, so now I need to learn asm to write bootloader lol.
