Been on hiatus from updating this for a while now.
Not a huge amount has happened in the last six months but here is what has.
Japanese no. plates have been added (unfortunately no photos of these yet).
Dual engine lid fans installed.

Water/Meth injection.

Both added to tackle the high IAT. Seems to be running well without the water injection being tune for yet. Planning to have her back in for a tune sometime between now and early next year.
I am also currently working on my own live readout display so that I can monitor things like IAT, boost pressure etc. This will comprise of an Arduino Uno R3 microcontroller, a Can-Bus shield and an I2C LCD screen.
