"Boost pressure of sensor" is an Actual Value in the Durametric and it is displayed in mbar. In my car, at idle it is 990 (this number will vary depending on how high above sea level you are - I think). The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being equal 14.696 PSI, 1013.25 mbars (at sea level). 0 Bar reading in the car is actually equal to 14.696 PSI or 1.013 BAR (at sea level) so the gauge is a measurement above atm (the Durametric is a total reading). 1.0 BAR reading in the car is an additional 14.696 psi or 1 additional bar of boost pressure.
Under acceleration, if I record a reading of 1569 through the Durametric it needs to be converted to match the reading on the gauge in the car.
1568 - 990 (reading at idle) = 578 mbar / 1000 = .57 BAR or .6 bar on the gauge or 8.5 psi.

Lucky that someone collected all the juicy Durametric threads together...

Great to know! Many thanks! So I guess the next question is where does the PLX guage monitor egts, before or after the cats?

Unless Ron has plugged a new sensor in somewhere, it's got to be reading the same sensor as Durametric.

thanks for taking the time, that is interesting results, as your egt never went over 1300 F, and i see you are running ~ 1.4 boost, that is funny i went for a spirited HS drive yesterday and i didnt data log but i was using my PLX GAUGE, and every thing was on the money except my egt went up too 1650 F, with 100 cell , (full boost, stock tune) so i am confused now, or am i missing some thing here, because what am I going to see if i do a tune with higher boost, theoraticaly it will be worse? unless some thing isnt right with my car?
I will have to some more digging in to this,or perhaps i will have to do a durametrics data logging!

i think my plx gauge might be the culprite as to how it is displaying data, i will have to data log it with durametrics and verify for sure

it seems like it is measured right out of the turbos in the above pics, so the plx has 4 cat temp reading (two are na) and they are interpreting this as egt which i dont think is right as cat temp should be higher then egt , no ? and which is what i am seeing higher then normal reading , i will find this out for sure with Dm logging,....

which exact parameter did you select for lambda and egt, etc, there are few egt,lambda parameters with have similar wordings, so my test is the same as yours. apples to apples ......
