At Wolf Motorsport, we work on many different types of vehicles.
One example of the types of vehicles we install the Wolf V500 ECU on is a Toyota Hilux Ute that has been modified to accept a Supercharged Toyota Lexus 1UZFE engine.
The installation is very nice and the customer has done a great job of the installation itself. But, of course, the original ECU cannot run the modified 1UZFE engine. So, he needs a programmable engine management system.
In this particular installation, the customer has installed the Toyota Crown wiring loom that came with the engine, so we have made up an adapter harness to go between the Toyota Crown wiring harness and the Wolf V500 ECU.
This allows a very quick installation, and we can get straight into tuning.
On top of all of the normal tuning parameters of fuel, ignition timing, idle control, etc, in this case we could install a alcohol/water spray system to help keep the intake charge as cool as possible.
An important thing to note with this type of installation is to keep things as neat as possible, with nothing that can move and maybe hit or be caught in the the belts or drop onto exhaust manifolds when we are tuning the engine.
An example of something that can be removed from the original engine, is the factory air flow meter. This can be removed, and replaced with an efficient tube to help improve air flow to the engine.
One great thing that the owner of this vehicle has done is that even though he has a pod air cleaner, he has covered it to ensure that the air cleaner picks up cool air from the front of the vehicle instead of engine bay air that has been heated by the engine and radiator. This will go a long way to improving engine efficiency.
Due to the increase in power, it's important to make sure the radiator is up to scratch. Using a larger, more efficient radiator will help in this regard.
Using the V500, we can control all of the original air conditioning system that came out with the engine. We can interface with the pressure sensor for the air conditioning, the magnetic clutch that engages the air conditioning compressor, and the switch on the dash.
Now we have excellent control over the whole air conditioning system. We can turn off the air conditioner compressor when the correct max system pressure is reached. We can also turn it off when the driver goes to a high throttle value (this is adjustable), so the compressor is not using engine power when the driver wants it all to go to the wheels.
We can also turn on the thermo fan when the air conditioner is turned on to improve the a/c efficiency.
This is a great setup allowing us to keep EOM factory style systems, but still get as much power as possible from the engine.
