Can an EMU be used on my car?

Most likely. 

Check out our large range of PNP adapters for connecting an EMU directly to your factory wiring harness.

It will depend on a few key factors:

Which EMU you are using.

The engine and sensors in your car.

How much stock functionality you want to keep.

How much custom wiring you are ok with doing, or finding a shop to do for you.

Check out which EMU has the required features and is right for your application

There are a few key sensors and calibrations that are important to know in order to run your engine with one of our EMU's.

The first and most important will be the 

Primary trigger/Crankshaft Position Sensor/Crank Angle Sensor: This tells the EMU how fast the crankshaft is spinning and the current position it is in. Your primary trigger pattern is important, we support pretty much every standard pattern as well as some not so standard ones. If you are not sure if yours is supported you can download the software and check. If you cannot find it. Send us an email and we can see if it is similar to an existing pattern or see if it can be added to the software.

Secondary trigger/Camshaft Position Sensor: This tells you if the crankshaft is in it's intake or exhaust phase. We support pretty much every standard pattern as well as some not so standard ones for this as well. In the EMU Black V3 and EMU Pro software you can pretty much define your own patterns so almost any pattern will work. If you are not sure if yours is supported you can download the software and check. If you cannot find it. Send us an email and we can see if it is similar to an existing pattern or see if it can be added to the software.

This sensor is required if using a multitooth crank trigger wheel (evenly spaced teeth with no missing or additional teeth). If your crank trigger pattern supports it, you can still run wasted spark without this sensor.

MAP Sensor: This sensor tells the EMU what the current pressure in the intake manifold is. This is mainly what is used as the load of the engine. It is important to know the scaling of your sensor or use an aftermarket sensor with a known scaling.

IAT Sensor: This will work alongside the MAP sensor and your VE table for estimating the fuel required by the engine. It is important to know the scaling of your sensor or use an aftermarket sensor with a known scaling. 

CLT Sensor: This measures coolant temperature and can scale fueling based on if your engine is cold or up to temp. It is important to know the scaling of your sensor or use an aftermarket sensor with a known scaling.

TPS Sensor: This lets the EMU know the current throttle position for either an alternate load source or for acceleration fuel. This is very easy to set up in the software even without knowing the scaling before it is wired in.

Wideband Oxygen Sensor: This will allow you to see if you are giving the engine too much or too little fuel. Our EMU's all have built in WBO sensor controllers but can also receive an analog signal from an external controller such as a gauge.

Fuel injectors: Fuel injector size is important in order to inject the correct amount of fuel. Dead times are also important and available from most aftermarket injector manufacturers. Our EMU Pro's can support direct injectors, it is even more important to have good calibration information for those.

Transmission: All of our EMU's can operate with manual transmissions. The EMU Black and EMU Pro can control a VW DSG transmission. The EMU Pro can currently control some basic automatic transmissions such as the A340, 4L60 and 4L80, and more to come.

CAN: Modern cars send a lot of information over CAN. The EMU Black and Pro have built in support for CAN and can send any message you tell it to. We also have the CAN stream for many vehicles already built into the software for you to choose through a dropdown list. These can be found in the software if you would like to know if your car is supported. They will often feature information like RPM sent to the factory gauge cluster and wheels speeds coming in to the ECU from the ABS unit.
