Quick EGR tables questions

[Scrufdog]

Browsing through my tables on my Burb, I see all the 'vs RPM' EGR tables stop at 4000 RPM, no higher. Does this mean there is no EGR activation above 4000 RPM? Or does it mean that 4000 and over use whatever is defined on the 4000 RPM line?

thanks

egr is a cruising range thing; i dont think they expect you to be cruising @ 4000rpm+....

this is accurate. generally, any table that stops before the end of your operating range will act as such. i'm sure there are exceptions, but i can't think of any off-hand.

Ok. Just looking around, would like to make sure EGR is tapered off by 3400rpm while full throttle.

Since EGR requires vacuum to open at low vacuum/full throttle you will not really have EGR opening anyway.
