May I ask question about delta dash here?

 

You may - you'll get **** all help on the public ecutek forum.

 

Thank you.

In the Delta Dash, I can read the lambda data from the a/f sensor #1 only. Can I just put this data times 14.7 to find out the a/f ratio? eg. the lambda data is 1.1, then let 1.1 x 14.7 = 16.17, and it reflects the a/f ratio is too lean. eg. 0.65 x 14.7 = 9.555, and it is too rich. Is this reliable? Can I see 1.1 or 0.65 lamda data in the delta dash? I don't want to spend money on buying a wide band sensor and paying the labour to install the sensor.

Can I read the exhaust gas temp. in the delta dash? (I don't want to install an extra sensor too.)

 

You can log using AFR instead of Lambda.
In Live data capture/Display options select <<convert Lambda to AFR>>

I'm not sure how you are seeing an AFR of 9.5 as I thought the Subaru sensor only read down to 11.2, unless your sensor is broken.
Are you getting a CEL for low signal output?

I don't know how useful the Subaru EGT sensor is - I thought it was just a basic indicator to show when the up-pipe catalyst was broken and have a slow response similar to the narrow band O2 sensor.
It cna be logged with delta dash, but presumably only on 01-05 WRXs that had the up-pipe catalyst fitted.

Butty, thank you very much for your detail answer.
