Unreliable....

And only used on an engine that's fully rebuilt shortly thereafter!

Actually the Power Commander is one of a number of fuel metering devices that work very well at what they are designed to do, which is adjust fuel / air mixture levels. Which is importent for engine life especially when an aftermarket exhaust is fitted.

I have never heard of one causing an engine failure, would it be possibe? Maybe but chances are other things have also been done to cause issues.

If there was a problem with them then they wouldn't be so popular in racing.

I have no idea - that is why I feel it is best to buy something specific to you vehicle.

The BAS version that I mentioned allows you to remove your map (via computer) and return it to original when you send your car in for service and when you car comes back to put you improved map back in.

As far as general software updates for your car goes - when the car is serviced if there is an update on what they have worked on eg gearbox then that will be done. If you just take the car in and ask for updates I believe most dealers will charge - certainly my dealer does.

I know of 3 separate units in separate bikes failing and pumping a cylinder full of fuel. And another 10 or so others that have failed during rides requiring the bikes to have the units removed to even run.

Dynojets products were the leaders but are now lagging far behind.

More and more bikes now have EPROM based ECUs and flash or real time tuning are becoming far more popular on newer bikes.

If the intercept box faults / fails and the cylinders run mid-fueled (lean for petrol / too rich for diesel) then extensive engine failure can result.

Even a loose connection could do it.

On diesels, very few bother to adjust timing they just punch in more juice.
