Q: Why does PowerCard only add fuel?
A:
It is true that PowerCard only adds fuel. We designed it that way to
keep it simple and affordable. Our belief is that in almost every
situation, addition of fuel is what fuel injected vehicles need. In order to meet stringent emission standards fuel systems
are mapped by the factory to be lean in cruise and everyday driving
conditions . If you decide to modify your vehicle with intake, header, exhaust, cams, and so on, these upgrades often lean out the fuel even more. PowerCard gives you the ability to add fuel exactly where you need it.
Q: You say it is easy to adjust, but fuel injection seems complicated. Can you explain?
A:
You're right in believing that fuel injection is complicated. Factory technicians and engineers spent thousands of hours "mapping" your car. The Miata's ECU includes numerous fuel maps to deal with a wide variety of load and environmental situations. The signals sent to your fuel injectors are the result of all this knowledge. Rather than pretend we can create a better map, we let your ECU calculate the load, and temperature, and price of coffee at Starbucks. Based on your airflow modifications, we use our proprietary algorithms to calculate how much additional fuel to add. The "heavy lifting" is still in the hands of your stock ECU.
Q. What if I install and tune my Miata with PowerCard and then go up to higher altitude?
A.
Our product attaches directly to the trigger wires of the fuel injector and only modifies the length or duration of the fuel signal. That way, all of the factory-specified and required settings for temperature adjustment, altitude and barometric pressure adjustment are totally unaffected and continue to function as originally designed.
Q. What if I install other performance mods after I have my PowerCard installed?
A. With PowerCard all you have to do is retune for your current set up. It is that simple.
Q. What is the difference between Batch and Sequential Fire and how do I know what I have?
A. Modern Fuel injection systems are classified as either Batch Fire or Sequential Fire. In a batch fire system the injectors are batched together in pairs and fire as pairs. In a sequential system each injector fires independently. See the attached document for further explanation and how to tell what kind of system is on your vehicle.
Q. Can PowerCard be used on Boosted applications?
A. If you have a Jackson Racing Supercharged Miata you can upgrade your current fuel management to PowerCard (click here) Other then this one application we can not deal with boost at this time. However, we are working on a Pro-Series PowerCard that will work with Boost, and Nitrous as well, and will have additional channels that can be used for clamping voltage, altering signals, interupting signals and so on.
Q. Anything else I should know?
A.
The main problem we face is when customers try our product after they have been disappointed by the results they got from using other modification
systems or from re-mapping their own system. Because our unit relies on the stock factory fuel maps, it cannot function effectively if any other
manipulation has already been entered into the existing system. You must remove any other form of fuel map modifications, chips, PC's, etc. before
using our product. Also, our product cannot fix mechanical issues that may already be present. Miata's are notorious for failed ignition wires causing misses and hiccups. While using our product, if you find that your fuel system is not responding as we suggest, there may be some underlying mechanical issues already present that you need to address before you can achieve maximum performance.
