SMT6 - THE SMART TUNER 6 PIGGY-BACK SYSTEM

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 User Kit includes the following items:

SMT6 Unit with Injector Driver
SMT6 Harness (Wiring Loom)
SMT6 Communications Cable
SMT6 Shorting Plug (Bridging Plug)
This useful product allows you to revert your vehicle to stock standard, should you need to remove the installed SMT6 unit for any reason.
SMT6 CD complete with all the Manuals and Software
SMT6 Unit with Injector Driver
SMT6 Harness (Wiring Loom)

A full list of the FEATURES AND BENEFITS of the SMT6 is included in the Feature Benefit list below.

More details on some of the important features are:

Lambda Feature: 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's extra injector driver allows more fuel to be added into an engine, and is ideal for Turbo applications. This extra injector driver can also be used for proportional nitrous injection.

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.

Mods please Sticky!!

I won't sticky it, but ill add it in the links in the main sticky just like we do to every other important thread in the section.

thanks for sharing, nice info.

Couple of questions for a Beta II (KIA Spectra5):

Does the SMT6 update live ... if I'm running and I make a change in a cell, is it acted upon ... is it live? Could I increment a cell value and watch the car react?

On the pin numbers ... my 06 has a wide band in the number one position so pin 43 is not used. Instead it uses 4 pins(19, 40, 41 & 53), all giving a " Complex Signal"

These are the pin outs I'm using: 2006 ECU Pin out (http://www.ottodawg.is-a-geek.com/ECU.php)

So which one do I connect to to read with the SMT6 for logging

Lastly ... on the right Amp(MAP) column ... is the multiplier the value in the box, so a value of "1" would leave every thing alone ... right?

yup it's live meaning that when a new value is entered it will affect the engine at that very instant

if you want to be sure, check then one wich varies between 0 and 5 volts with a DVOM or a scope
but then,you'll have to get some reference for the AFR to volt conversion,i'm not sure if hyundai uses the same chart then most comercially avaialble wideband

Lastly ... on the right Amp(MAP) column ... is the multiplier the value in the box, so a value of "1" would leave every thing alone ... right?

yup ''1'' means that it won't affect the numbers on the 8 x 16 map

[bmxdad]

Yes ... thanks for the answers Dennis...

So, in N/A form, you think leaning it out a little when it goes in to open loop would get any gains.

[Denisst99]

yup lean it out at WOT
you'll gain a few ponies

i think i was running -6 at 3500 rpm to about -13 at 7500 rpm
(car doesn't have any rev limiter)
