• You have modified your engine, and the present system can't cope with the new engine parameters.
• You want to convert a carburetor engine to fuel injection
• You want to learn more about engine management
• You race
• You are technically minded and you want to "play" with the engine and possibly reduce its fuel consumption.

Don't use it when:

• The present ECU is faulty and the replacement costs too much.
• You do not own a laptop computer

The system is ideal for high performance engines, which require precise control over the entire performance range. It can be adapted to normal engines, but it is not an alternative to your existing fuel injection system. The original manufacturers' systems are very good, and by replacing it with our system you may be able to tune the manufacturing tolerances out, to which the original system was subjected. This may be difficult and may cost a lot of money and time. It is not worth it!

Can't we make a system for a particular car? Yes, we can, but it defeats the object. If it’s for a standard fuel injected engine, our system isn't better than the original system with the exception that you have control over it. If it’s for a standard carburetor engine, then it could be done. If it’s for a modified engine, then the level of modification requires different tuning, which we can't provide, but you can with the XMS!

Look up Piggyback systems. They work "together" with your existing system and extend its life.
