Default Getting ECU manager to display PSI and AFR

Can this be done easily? Call me a dinosaur but my head works better with these values rather than KPA and lambda.

yes it can be done, you have to set the Input sensor calibration to be based on the PSI calibration vs a KPA

Yours says PSI abs whereas mine says KPA. Could it be because my MAP sensor is a Delco 3 bar?

And how about Air Fuel Ratio, AFR instead of Lambda???

i use a different pressure sensor,

you want to use calibration #21, instead of calibration #15 for the Delco 300kpa sensor.

re AFR,

the quickest guess is to insert a math calculated field in i2,

Code:
AFR = Lambda2 * 14.7
you need to load an equivelence table to get it closer to accurate, its totally dependant on what fuel you use, e85 will have a different AFR vs Lambda to U98

safer to use Lambda.
