Q: Will this work on my make of car/engine?
A: Most likely. Some engines will be easier to adapt than others.

Q: What other components will I need?
A: Depends on the application. Some cars can be adapted with little or no extra components. Others will require substantially more parts. For example, a German car using an early Bosch EFI system requires one extra temperature sensor, and a replacement throttle sensor. A car that normally runs on a carburettor, could be a challenge.

Q: Can you tell me what I need to get this working on my car/engine?
A: Probably not unless I have done the same conversion. Read the Megasquirt manuals & forums. By far the best thing to do, is find a forum of others that have already done the conversion for your engine model. It helps to know what components you can successfully reuse, and what new/replacement parts you need. It's also worth getting a copy of someone elses settings to get you started too.

Q: Do I need a O2 wideband sensor?
A: No, but it helps. Megasquirt can tune itself which simplifies the setting up process. You can always sell, or reuse the sensor on another car.

Q: What benefit to you get from MS2?
A: MS2 has a faster processor, higher resolution, and it's where all the development is happening right now. However, MS1 does most things that people want. You can always upgrade the processor later.
