FAQ - SMT


General
 
Is the SMT DIY and reprogrammable?
Answer: The SMT is DIY, but will not be sold to the end user unless your dealer has a wiring diagram for your specific engine.
 
What does the single unit development kit come with?
Answer: 1 Smt6 unit. 1 Communications cable. 1 Smt6 wiring harness. 1 Test jig. 1 Developers CD.
 
What does the developer’s kit contain?
Answer: The standard developers kit comes with one communications cable, one developers CD, one test jig, five wiring harnesses and five SMT6 units.

What if my car is not on your list of diagrams?
Answer: In this case you have two options: As we are constantly updating our list of diagrams, there is a chance we have the diagram you are looking for but it is not on the list yet. E-mail us and let us know which car you are looking for and if we don’t have the correct diagram we will see if we can make one. Failing to find information on the car it is still possible to install the unit by tracing the correct signals by using an oscilloscope.
 
What is a SMART TUNER (SMT)?
Answer: It is a piggy-back system, which changes signals to and from the engine. Allowing you to remap your engine for better fuel consumption and / or power. Click here for More Information
 
What is the cost of the SMT fitted to my car?
Answer: Please contact your nearest dealer for a price on an SMT. You will be surprised at the price!!
 
Why buy the development kit?
Answer: The kit is exactly what it says it is, a developers kit. It comes with everything you need for a new application, which includes the developers manual (on CD) and the latest set of wiring diagrams both of which are not available on the website.
 
Technical
 
Can I raise the RPM limit on my car?
Answer: No, the SMT can impose a limit but it cannot raise it.
 
Can I raise the speed limit on my car using an SMT?
Answer: Yes, the road speed governor can be raised or lowered using the SMT.
 
Can the SMT do closed loop operations?
Answer: Yes. You can tune a closed loop engine. When the closed loop is active, and when it is inactive. See: SMT7.
 
Can the SMT do multi-coil?
Answer: Yes, by gaining access to the input signal from the engine or if it is a twin coil by using the interlaced mode of the SMT you can modify the output signals of the ecu.
 
Can the SMT do supercharge and turbo cars?
Answer: Yes, the SMT6 has an extra injector driver that can be used to drive extra injectors used to add more fuel in turbo applications.
 
Can the SMT remove any Lambda sensors?
Answer: Yes. But you may not want to do this. In most cars lambda is active from idle to cruising only. Full power is seldom controlled by closed loop. Don’t remove the lambda, just tune it.
 
Can the SMT remove my MAP sensor?
Answer: Yes, the SMT7 can, but you need a MAP sensor. First it learns the MAF signal, and then it copies it to the tune map. After that you need to do some fine-tuning.
 
Can the SMT retune a LS1 engine?
Answer: Yes. The SMT7 is your answer.
 
Can the SMT6 support nitrous injection?
Answer: Yes, this is a new feature that will allow you to control a nitrous injector proportionally via the extra injector driver.
 
Can the SMT6 work in a carburetor driven engine?
Answer: The SMT6 can retard and advance ignition signals going to the distributor, but will not be able to do anything for the fuel with these types of cars.
 
Does Perfect power supply tune maps?
Answer: No, this information belongs to our dealers. We do not have any maps of our own. Please ask your dealer or contact us!
 
Why does the WINDOWS software not allow for greater than 60-teeth?
Answer: The frequency of the waveforms for signals greater than 60-teeth becomes too fast for the SMT to process. Watch out for the SMT8.
 
How does the No-Tune option work?
Answer: The No-Tune option is a feature designed for developers who don’t want other users to see their maps, once enabled the words No-Tune replace all data on the maps.
 
How much extra-power will this unit give me?
Answer: We can't answer that, the SMT gives the laptop the ability to tune a fuel injected car much like a screw driver gave the tuner the ability to tune a normally aspirated car, so your actual power gain will depend on your current setup.
 
What are odd signals?
Answer: These are signals with an inconsistent time gap between teeth on the crank wheel, producing waveforms that are difficult to replicate. Only the SMT7/8 has the ability to handle odd signal retard and advance. The SMT6 can handle odd retard!
 
What is a balanced signal?
Answer: This type of signal occurs mainly with missing tooth magnetic signals. Both wires of the sensor are “live” and contain a wave form. The one is the INVERSE of the other.
 
Why use a balanced trigger signal?
Answer: It is a nice method of avoiding electrical ignition noise.
 
What is the difference between your SMT and our competitors products?
Answer: Our unit is easy to program and you can also make a change ONLINE. The unit will automatically remember the tuning. We have one unit for all applications. We use the same wires as our competitors.
 
What is the map switch used for?
Answer: The SMT can store two pages of maps in memory, this will allow you to tune the car for two separate applications and then switch between them via a dash-mounted switch. One map can be for low grade fuel, the other for high octane.
 
What is the memory loss problem found in the SMT5 and has it been resolved in the SMT6?
Answer: Unfortunately the SMT5 would scramble its memory on some cars, a solution for this problem has been found and an application note is available on the development CD. This problem has been resolved in the SMT6.
 
What STAND-ALONE features does an SMT6 have?
Answer: The SMT6 can adjust dwell time on standard square wave ignition signals, making it perfect for controlling ignition advance and retard on distributor driven engines. It was not designed to be a stand-alone unit, but some people use it as such.
 
What is different on a SMT7?
Answer: It cost more! But is performs all the tricky tasks the SMT6 can’t. Over the years the motor manufacturer got smarter in avoiding the SMT6, so the SMT7 is the answer to them.
 
Are you planning a SMT8?
Answer: Yes, we are working on it! Because the car manufacturers get smarter in avoiding after- market tuning devices, we have to bring better devices out to stay in business. However, the SMT8 will break with the fundamental principle of the SMT6 and SMT7, and it will cost more. But we are confident that it will be able to tune ANY engine, even the ones which are not out yet.
