Perhaps this means a longer duration cam can net some top end gains :O

You might be right, but that is the static duration.

Considering VVT, it might not be as bad as it seems.

Serial, also remember effective duration. (Yes I know I've told you before...) Because of how slowly they initially open you usually cut ~50 degrees of the advertised duration.

eg:

3SGTE 256 degrees but 204 @ .050" lift
2JZGE 248 degrees but 200 @ .050" lift

So it seems like he was able to extract the ROM. Interesting...

Do you have any screenshots?

If it uses the Renesas SH7059 found in the Euro Diesel, more info can be found below.

Apparently the file size is only 1MB, which suggests it's an SH7058.

Note, none of this is first hand info ... I don't have access to a car yet.

Good job! I've just sent the pictures to my friend who works on many Denso ECU.

Many thanks again! ^^^That was pulled from an FRS, so the BRZ should be the same.

This is also available for piggy back stuff and whatever else would require tapping into the ECU wires.
