Thoughts on Barometric correction

[Davidv]

Hey,

Running an NA 2 litre engine with an air intake that draws air from ahead of the radiator panel, which is a high pressure zone at speed.

Not sure if this is enough to make any tangible difference, however...

Currently the barometric correction comes from inside the ECU, which is in the cabin.

Would there be any benefit in having an external barometric sensor at the point where the car's air inlet is instead?

As I guess the 'local' atmospheric pressure from where it draws air is the important bit?

Or is it such a small difference as to be negligable.

I've heard of people having difficulties tuning 'ram air' intakes for reasons of changing VE with speed, but it seems like using baro compensation from this area might be the way to keep a consistent tune.

Any thoughts on this?

Thanks

David
