History
Initially, the car was with 2.0 4g63t + Evo manual transmission + garrett gtx3071.
But there was one unpleasant incident. And I thought about changing the config









A 4g64 was purchased to build 2.4 liters










Next, the process of preparing for the engine assembly. Building custom pistons. Purchase of parts, boring..

 

modifying the manifold flange for an increased throttle body

my new tires

 

prepare to new exhaust

buying something new in exterior

okuyama spoiler


Okuyama and Damd front bumpers






some diffusor

 

Assembly of the AT gearbox after the Exedy clutch fail



Let`s do it

 

Evo front LSD




front mount engine and AT coolers and fat coolant cooler




Pajero Evolution carbon knob






 

Buying evo 9 mivec head






some hose







ready to assembly






First start

 

Before buying a evo head, of course, I thought about how the mivec solenoid control will occur. From the factory there were no automatic cars with such a head.
I made a controller that controls miveс and wiring for the solenoid and intake camshaft sensor.

Also a mini dash was developed for the stock instrument panel in this controller. Which communicates with the stock ECU via the DMA protocol and receives any data to display.
The controller calculates the current position of the intake camshaft based on signals from the CAS and Cam sensors. I also modified the ROM program for the functionality I need.
The target angle is taken from the standard ECU via DMA and rotates the intake camshaft by the desired number of degrees.

The first version looked something like this






Solenoid test


Mini dash

 

I also rewrote the calculation of air and transferred the car to speed density.
So I think it is the world first AT car on true speed density with mivec on stock ECU

something in between from a configs

 

how about evo steering wheel + paddle shifters?

 

My torque converter is 2200 rpm and it is very little to inflate the turbine (stock torque converter 3200 rpm for Airtrek, 3800 rpm for Evo GTA).

Testing a new launch control algorithm with different settings and different throttle position.
This is my torque monster

Added pseudo random spark and fuel cut, like a Motec. Allows you to specify a seed that changes a pseudo random sequence of cuts. What ultimately affects the sound of launch control, rolling launch, and similar features

And immediately did DSG burp (random spark cut with spark retard) on gear shift
