SAAB trionic t7.7 immo off advice

[Panathaole]

Hi

I need to make immo off a Saab trionic t7.7 ecu.....

It is possible with common tools?

As I have read the flash is not enough to make immo off, I have to read the mcu too.

I can't find emulator for this ecu...

Any info?

Thank's

A 29BL802 flash? Post your dump and let's have a look. :)

If you look on YouTube seems to be few Vauxhall’s with Saab engines, if that helps
worth asking around

It's possible to do immo off only with flash?

That's good news, I open up tomorrow the ecu to check the flash chip....

I can't find any info about this ecu on Opel cars, only in Saab....

The flash is AM29f400bt, the immo is in flash?

If yes I desolder and post dump...

Read and post the dump. I've done a few of those on 95 models but can't tell until I see the dump. :D

Again I say, read and post the flash, if just for my curiosity, LOL! What do you have to lose, other than 15 minutes of effort. :biggrin:

Is not possible by reading directly?

You can read it by obd, or on bench, no need to desolder anything.....
