This new product from Perfect Power has been designed to leave all competitors in our wake. With new features and ideas that were mainly supplied by you.
Tuning is now possible on every car, motorbike, quad and wet bike. The “Can’t Do” phrase is a thing of the past. The SMT6 and the new SMT7 are designed to be tools for every conversion. You could even say they would be part of every modification shop as a stock item needed for conversions.
The new SMT7 with many more features and new updated easy to use software is available in two versions: The SMT7 and the SMT7D (like the SMT6D!).
The SMT7 original concept was that of a “supplement” to the SMT6, but customer demands for a single product having all features is growing. So, we are adding more features every month. And we are using the SMT7 as a platform for specific OEM requirements. In other words: The SMT7 is the product to watch for new developments!
Here are some of the features of the SMT7, which makes this unit unique in its class:
BOOST CONTROL
The boost control feature is applicable to turbo installations where the boost must be controlled. This is particular important when the engine is NOT de-compressed, and when a rather small turbo is used. In most cases the engine has the tendency to “ping” between 2000-3000 RPM. The boost control can reduce the boost at the critical RPM and then increase the boost significantly at the higher RPM’s where the airflow is restricted. The Boost control feature can also be used as a standalone function for aftermarket boost control.
CLOSED LOOP LAMBDA (FUEL LOOP)
The SMT7 can work directly with a narrow (0-1Volt) sensor, or with a 0-5Volt wide band AFR signal from a WBC or other external device. You can run your conversion in closed loop, partial closed loop, or open loop: It is freely programmable!
TWO ANALOGUE SCREENS
You can tune lambda up to the point when the ECU switches closed loop off, and then you can tune the airflow meter on the second screen. Of course, you can tune ANY two analogue signals simultaneously!
LAMBDA TUNING
If your engine is closed loop controlled by a narrow band lambda sensor, then you can tune it. Changing the ECU target to a more economical, or to a more powerful setting does this. You can also tune WIDE BAND closed loop, but you can’t see the AFR directly. Of course, you see the effect!
INJECTION CONTROL
This is for controlling EXTRA injectors, which are placed in the manifold to SUPPLEMENT the original injectors. This is by far the best way to get more fuel in to an engine after adding a supercharger or turbo.
IGNITION CONTROL
This is a little trickier! The SMT7 can “modify” two engine signals simultaneously, thus giving you retard and advance timing facilities on all engines. Ignition control of complex (multiple gap, CAM pattern) is now possible.
SETPOINT CONTROL
It is by now a standard feature on all our models. The SMT7 has three set point outputs and 12 set point functions, with the possibility to link functions with a logical AND/OR. Example: Switch a relay on/off when the throttle is more/less than 75% AND RPM is higher/lower than 3000.
MORE INPUTS/OUTPUTS
Instead of sharing wires between functions, we have assigned a wire to every function. This makes the unit easier to understand and wire up, which results in two connectors with a total of 36 wires. Since there are so many features in the SMT7, Perfect Power will be shipping the units with only a few wires connected and loose pins to make up the rest of the connector. This is done to make the installation neater and not to have excess wires, not being used, hanging around.
FREQUENCY MODIFICATION (ROAD SPEED MODIFICATION)
The road speed of a vehicle is measured via a frequency, which is proportional to the vehicle road speed. The SMT7 can be used to adjust the frequency to compensate for different tyre size, or to remove the road speed governor.
FREQUENCY AIRFLOW MODIFICATIONS
Some airflow meters transmit a frequency to the ECU, which is proportional to the airflow. The SMT7 can map this signal (modify the frequency via the ANA2 map), thus allowing you to tune the engines fuel.
PWM MODIFICATIONS (FUEL, BOOST)
Some PWM signals (such as boost control) just need modification! The SMT7 can modify a PWM signal (Modify the width of the pulse) without changing the frequency, via the ANA2 map. However, the output is a “signal”, and needs to be amplified to drive an injector.
NEW SOFTWARE
The SMT7 has new software with an easy to use screen layout. The screens have more tuning versatility with extra columns featuring engine temp, air temp and manifold pressure.
The “WINDOWS MOUSE” operation has been supplemented by key board commands for row, column and field tuning, which are more accessible when operating a laptop computer in a car.
All tuning fields can be labelled in the field, and screens can be turned off if not needed. This is very convenient for customizing the software to your application.
LANGUAGE
Agh! We are working on it!
8 TUNING SCREENS
Each screen refers to a particular tuning operation, and it displays all vital engine data. All setup parameters needed by the operation are located on the screen, which eliminates the need to confirm them, or to switch screens in order to change them.
HISTORY
The SMT7 provides a driving history, which can be uploaded.
MAX RECORDINGS
The SMT7 provides a driving history, which can be uploaded.
LOGGING
Of course, you can log all engine data and some SMT7 data and play it back
UPGRADING
The SMT7 can be “RE-FLASHED” in the field after receiving the new firmware via the Internet. KNOWN BUGS We are not proud of “bugs”, but we have them. The known bug list is our way of informing you of the next upcoming software changes, and possible “work around” solutions.
HELP
The manual is linked to the screens and subject index, which facilitates a quick reference.
TRIGGER TYPE
Most engines are different and have a different trigger. The trigger signal tells the ECU how much an engine has turned and which cylinder is next. 32 trigger types are possible. Most types are applicable to more than one engine and manufacturer. The trigger types are continuously updated, and eventually the most common types can re-flashed to suit your needs.
Since there are so many features in the SMT7 Perfect Power will now be shipping the units with only a few wires connected
and then loose pins to make up the rest of the connector. This is done to make the installation neater and not to have excess
wires, not being used, hanging around.
The SMT7 and the SMT6 are going to run parallel, as there are differences between the two products that make them both handy tools. The new development is on the SMT7 however, because it is a “bigger” platform, has more “umpf”, and has more input/output capability.
OEM The SMT7 is the ideal OEM tool. It provides a platform for all applications, and we can provide a 4-week “turn-a-round” from idea to medium quantity delivery for your very own customized unit. If that does not excite you, then talk to our engineers.
FUTURE The SMT7 has settled down nicely! That is the point when the engineers get restless and think about the future. If you share our enthusiasms then talk to Peter, Rolf or Klaus.
