The SMT6 is universal piggy back system, designed to allow you to tune almost ANY electronically fuel injected engine.
Signals are modified on maps found within the SMT6 unit itself, and the Windows Tuning Software. Installation and tuning is simple and once installed the engine can be re-tuned by anyone with a laptop or PC, comms cable and the Tuning Software.
An average installation consists of connecting 6 wires to the vehicle's original wiring loom, changing the settings of the SMT6 in the setup section of the Tuning Software and voila! - you are ready to re-tune the vehicle. An experienced installer can install an SMT6 unit within 30 minutes!
The SMT6 product is packaged in two kits: the SMT6 User Kit and the SMT6 Kit.
The SMT6 User Kit contains all the necessary items for a First Time or Once-Off installation.
The SMT6 User Kit includes the following items:
This useful product allows you to revert your vehicle to stock standard, should you need to remove the installed SMT6 unit for any reason.
A very useful accessory to use with the SMT6 unit, is the SMT6 Test Jig. This product allows you to test the SMT6 unit and confirms that all components are working 100%. It also assists with the installation of the SMT6, as you can test for any faults at each stage of the installation. The SMT6 Test Jig is affordable and is available to purchase as an optional accessory for only 31.43 US Dollars!
The SMT6 Kit is for a Repeat Installation. There are certain things that you won't need to get again, as you would've already purchased them in the SMT6 User Kit, e.g. the SMT6 comms cable.
The useful SMT6 Shorting Plug, would need to be purchased as an additional item.
The SMT6 Kit includes the following items:
- SMT6 Unit with Injector Driver
- SMT6 Harness (Wiring Loom)
A full list of the FEATURES AND BENEFITS of the SMT6 is included in the table below.
More details on some of the important features are:
With the SMT6 it is possible to read the lambda sensor, as well as modify the lambda sensor signals. There are two modes of lambda tuning - linear and non-linear. The linear mode tunes according to the voltage of the sensor, while the non-linear mode allows you to tune according to a lambda value. Both tuning modes are selectable via the setup screen in the Windows Tuning Software.
The SMT6 has an output which can be enabled according to an RPM setpoint, which is mainly used with CAM switching applications. This output can also be used to set the airflow, temperature and analog deflection points.
The SMT6 also has an input for airflow sensors and temperature sensors, and each of them has a separate map that can be used to manipulate the fuel, extra injector and ignition signals.
FEATURES & BENEFITS OF THE SMT6
All piggy-back systems rely on the exiting ECU to provide the fuel and ignition to an electronically fuel injected engine. Therefore, they are also bound by the limitations of the existing ECU.
Fuel is typically modified by changing the load sensor or lambda sensor signal. Ignition is done by delaying or advancing the crank angle sensor's signal. The piggy-back system tricks the ECU into thinking that it is running under different conditions thereby allowing for a different output.

Frequently Asked Questions
What do the values of the Smt6's ignition map actually mean on the engines timing?
The Smt6 doesn't know what the engines timing is but it can advance or retard it. Positive values in the ignition map will advance the timing and negative values will retard the timing. Any value used will be added or subtracted from the base ignition timing. Zero entry will be the stock or base timing.
The engine temperature is bouncing up and down in the side table, I have not connected the Smt6 piggy-back to my engine temperature sensor, and how do I stop this?
Ground the SMT6 engine temperature input, it is pin 11 the green/yellow wire.
The SMT6 has an aluminum tab with a hole punched in it; must I mount the Smt6 through this hole?
You can if you want to. The tab is a heat sink for the extra injector driver, if you are using your Smt6 to drive injectors, boost solenoids or nitrous and the tab is getting warm then mount the Smt6 to a larger piece of aluminum to help dissipate any heat build up
I have a wiring diagram for my car but out of the 22 Smt6 wires I only use 7 wires why?
Most installations use 7 wires; check the full list of the other wires in the SMT6 Developers Manual.
