Hi All!
This is a thread where my old junk is going to run turbocharged 1G-FE engine on Proteus board.
Old photo from time when rust didn't eat so much yet :lol:
It's a rebuilt 2.0 Inline 6 motor with added TD05 turbocharger, decompression plate to lower compression ratio to 8.5:1 and Mazda RX-8 injectors to fuel it.
Of course there were lots of smaller mods like changing returnless fuel system to return style, more capable fuel pump etc...
The original ECU is a no-go as it has a specific dual Toshiba MCU architecture with the software in built-in Mask ROM.
Still in progress, the goal is to have the PnP to just replace stock ECU with rusEFI ;)
At the moment it's about 90% re-created functionality of OEM system to control DBW, VVT-i, ACIS systems etc.
Still need to dyno it, at the moment it's about 1.0 bar of boost, so should be 300hp-ish :roll:

Really what I am asking is what parts of https://rusefi.com/online/view.php?msq=1561 would be useful for https://github.com/rusefi/rusefi/blob/master/firmware/config/engines/toyota_jz.cpp

147 reference is part of me being confused in JZ variations. Please do not attempt to explain JZ to me please just PR progress if there is any progress you can PR.
