Oh. OK.
Well I'll be able to test tonight then

Brilliant. Ill jump out the the XR8 today and grab a read

Somethig Id like to know is if the PCMs are cloned. As in if all security details are passed on if I write to another compatible ECU?

Seed key routine is stored at 0xC094 (see a few pages back I posted it up). I don't flash 0x0 -> 0x10000 as if that goes wrong you will brick the PCM. This is where the RTOS etc lives I believe. All I do is flash the calibration data from there onwards which is similar to what other tools do.

So if say you have a custom tuned PCM and they have locked it by modifying the security routine to use a different seed not only will my software fail to unlock the PCM but if it did it wouldn't write this back to the PCM.

I may investigate doing a full write down the track but as the only use would be to bypass copy protection from other companies I'm not sure it is something I'm interested in doing.

The software does however copy the entire VID block and VIN etc so you are essentially cloning the PCM, eg all calibration data and VIN. Not sure how you disable PATS normally, I know there is a bit you can disable and you can change the VIN in the code but I believe you need to do something else as well.

Iif anyone knows the full PATS disable procedure if you could post it up that would be very interesting.

Yeah, I understand where your coming from.

But was thinking more the lines of a spare during R&D (And as a spare for 'just in case'). XR8 ECU's don't pop up regularly, so as time goes on, would be good to have a perfect spare to just drop in
Not sure Iv heard much in regards to ECU failures for the Falcons, but its something Id be interested in having sitting around. Plus passing it onto the next owner.

What goes around.. comes around (Well.. I hope!)

Providing you get another ECU from the same model I don't see any issue as the RTOS should be identical. Eg all BF turbos etc seem to have the same part number from what I can see.

Sweet as. Guess we will find out!

*Edit

Hmm.... I see a good FPV ecu to pickup... I would 'guess' it would be the same ecu being both 5.4L V8's...

I know people have flashed an "fg" tune into a bf before. However I'm not sure exactly what they have done, eg just copy the same maps over the top of each other etc. I suspect that they haven't actually flashed the entire PCM across.

This is a BA FPV ECU Im looking at.

Number: 3R23-12A650-AKA

*Edit
Ahhh.. its a 5speed manual. I have a 4spd auto... so a full flash would probably be needed

Auto and manual will flash over each other no problem, not sure if the car will actually drive but the PCM will definitely accept the file.
