I have started a freshly built rb26 today for the first time thanks to the standalone course

the engine is plugged to emtron kv8

immediately after I started the engine I have noticed lambda live is stuck at 1.00 value and even after engine heated up nothing happened

could this problem be a software adjustment or it can be related to the sensor itself?

also I should mention I am using the old sensor and the engine had oil burning problem before the build.

Hello can you post your tune file and a log for us to look at we should be able to help from there?

Regards Ross

Was the sensor with this ECU working before the rebuild. If not, I would confirm the wiring and ECU configuration first.

what is the best way to upload the tune ? I'm trying to upload the file but upload sites don't accept ecf files.

well I can't confirm if it was working before the build but the wiring is good

hope this link works:
