Wondering if my standard 3T Engine replaced by this one, disable speed limiter..
Twinsparks, baby!!
Check this out..!!
------------------------------------------------------------------------------------------
This is the original 3T-GTEU EFI, completely analog, manufactured by Nippondenso, based on the Bosch L-Jetronic. The control unit is mounted behind the blower duct, above passenger's feet. The knock control unit should also be around there, in my case it's on the right side of passenger's feet.

AIR FLOW SENSOR
this sensor is of the flap-type. It measures the air entering the engine (assuming no intake leaks).
When the flap is totally closed, meaning no air is entering the engine, fuel pump is not running. This is achieved by a switch connected to the flap, which connects the fuel pump ground (connector FC) to chassis ground (E1) only when it is open at least partially.

Air temperature sensor is the third function the whole air flow meter serves, this is a standard automotive NTC resistor (connector THA). Here's the resistance curve:


COOLANT TEMPERATURE SENSOR
This is identical to the air temperature sensor described above, except that it measures the coolant temperature below the waterneck. Idle speed and fuel cut-out/cut-in during deceleration depend on this sensor

THERMO-TIME SWITCH
Grounds the cold-start injector for 5-12 seconds after starting.

THROTTLE SWITCH
The throttle switches are mounted on the throttle plate axle, and in this case only have three possible outputs, idle (connector IDL), wide open throttle (connector PSW) or neither. Connector TL provides the voltage which the switches deliver to IDL or PSW when closed.

PRESSURE SWITCHES
The EFI itself uses 2 pressure switches. First one is used for enrichment (connector PE) above 0.15 bar (2.2psi) of boost. This pressure switch measures the pressure through a vacuum line (ok, ok, it's not in this case always under vacuum) from the intake manifold. The second pressure switch is for fuel cutoff (connector PC) above 0.5 bar (7.3psi) of boost. This one is measured before the throttle body. There are two reasons why this does not seem to be a good idea to keep functioning: the fuel cutoff is not complete, it will lead to a very lean condition under high load and is BAAAAD for the engine. It had not caused any damage, but it did render high-speed drivability to unbearable.
Oxygen sensor & sub-oxygen sensor
Oxygen sensor is used to keep the air-fuel mixture at 14.7:1 (lambda=1) under "normal" driving conditions, in this case intake manifold vacuum has to be over 0.3 bar, engine fully warmed up (Coolant sensor THW) and the fuel cut-out and idle must not be active. That is, it's only used when cruising with only moderate acceleration or deceleration takes place. The connector for oxygen sensor is OX. The sub-oxygen sensor (connector OT) would be mounted after a catalytic converter, but I have neither.

VEHICLE SPEED LIMITER SENSOR
Limits the vehicle speed to 180km/h, this is obligatory in Japanese market vehicles. Guess is this still connected ;) Connector VMAX. Just clipping the (originally pink, but check the connector picture) wire will disable it, if you even have the sensor mounted.

You never did..

The night before the moon died you realized
You kept flowers that you picked locked away
Were never to be seen by naked lovers' eyes

The night before the moon died you realized
You had your chance to make it right
But you never did

You lost this one now, girl
You had your chance to change your mind
You had your chance to make it right
You had your chance to save your life
But you never did

Goodbye

I could never replace who you are

I could fall in love
I could pick a flower
I'll give it a face
But it would never replace who you are

I could sing forever
Get drunk on guitar
Feel the drums and bass
But I could never replace who you are

I'd take a train to nowhere
A rocket to mars
I'd get lost in space
But I will never replace who you are

I could set this cold blue world ablaze
But the sun would still rise
And I would never replace who you are
