hello everybody.... I have this T7 ECU that I am trying to do immo off..My eyes are about to fall out from reading all over the net..... I purchased a Combi Adapter I can read ecu bdm just fine and I can erase and write my original file back to ecu just fine but I cannot write any open bins to ecu.... So I did a full disassembly of my original file and I cannot find any of the immobilzer tags locations in the .asm file using notepad++..... I really need to immo off.....


Backstory car came in no start from prior locksmith making key.... so i opened twice and immediately notice twice mcu was soldered on rotated so that pin 1 did not line up.... I removed mcu read data and programmed new key then soldered on mcu correctly but no go did not work..... I just need to get started I have wiring diagrams to bypass starter relay... I do not have tech2 so I cannot marry a replacement twice....... please help attached are going to be files from twice and ecu ..... also I am going to link a youtube video making key... I am very familar with immo's just not saab.. this is my secod saab job this week and this one is being stuborn.. ......

Check your pm.....

I have send you to your pm a thread that have all the info you need to do immo off that ecu, it need some time, if you can't do it I try to make it tommorow...

Good luck....

[alex_r_2001]

Thanks I read that thread a couple of days ago.... My ecu file after full disassembly does not have any immo data anywhere ... Im not very familiar with this system... If you can please look at my ecu file and if you can figure it out would be great..... Thankyou.

I try to edit your file, but is not possible and i think is bad reading, can you tell me with what program you have read the ecu? (not the tool, the program, you must read it ONLY with TrionicCANFLASHER.......the flash have some kind of compression and only trioniccanflasher can decompress correctly.....)

I try again with one of my οwn reading and work fine....

Bmd tool with johnc qcombi adapter

My diagnostic tool can see ecu no problem live data and everything ... but I try an use tronic can flasher with options obdsx and j2534 and and johnc combi and nothing see can... so i then wired directly to can network Because car obd port does not have can... but still do not see can (ecu) with any adapters other then diagnostic tool....

With good battery on a charger that I use for j2534 passthru programming.

Can you send me your file so I can try to write to ecu... I've tried to write other files open bins from other forum and bdm tool gives error to write... but my file i erase and write perfectly...

[Panathaole]

i am pretty sure the combi adapter work very well with trionicanflasher...... i think you doing something wrong.....

unfortunately, i can find in my hdd only a file for convertible version, you probably have abs, and radio error but the car will start, it is much better to try reading the original ecu to make immo off......

try it on bench..... i make this work in 3 ecus with a OBDLink sx (the cheapest way) and works fine with trionicanflasher....

waiting your feedback....

Saab I have is convertable.. thankyou I will try.

[alex_r_2001]

yeah i pretty much give up on this one... I tried combi on several different laptop with ecu on bench as well as in car.... I made my own db9 connector with ground clamp.. db9 can lines ran diffectly to ecu on bench.. tested voltages on can lines both on ecu and from combi separately and 2.5volts on can hi and low.. with diagnostic scanner I can see ecu without any problems just t7 suite or can flasher does not see ecu... i tried with obdsx link and j2534 and johnc combi adapter... only way I can read erase or write ecu is with bdm ... i can only write back original file thas was originally read from ecu, cannot write any of the files that are immo off.... and fron what I have been told is my original files does not make any sense... i give up im waving the white flag..... to much time wasted on this project... to all the members that helped me out you are very much appreciated.,.....

[Panathaole]

Sorry to hear that....

Is not that difficult I think, I am pretty sure you had done something wrong......

[alex_r_2001]

update... I ordered a new ecu and was able to read and flash file without any problems.. using can flasher through can lines... original ecu was defective all along...

i have attached the orignal information read from donor ecu... can somebody please make this file immo off and change vin number to the one that is in the text file I attached . please and thankyou
