Lambda Gauge
Hello everyone, i have a question regarding lambda gauge when i cruise usually its yellow lights and .95 to 1.0 when i speed the yellow lights turn green and reach to .70 or .71 is it normal or something wrong?
Thanks in advance |

The engine will go into "power enrichment" at some point (based on throttle input, RPM's, etc.) which is basically just adding extra fuel for more power, cooling, etc. Every engine is different but 0.7 seems low, which is ~10.3 AFR, whereas from what I understand most engines "prefer" somewhere between 12 and 13 (0.82 - 0.88 lambda). But to answer the question, yes, it is normal to see a lower lambda when having fun.

If you have modifications a lower lambda (rich) under heavy load is much safer than running lean. As long as its running good and your plugs aren't fouling then your good.
