Hi,
I have hondata K100 with the original hondata calibration, supersprint cat back, and stock airbox with hondata mod:
Can someone analyse the A/F of my car on the dyno (lambda):
is the A/F rich, lean or good?
k100 calibration - A/F
First, I'll like to point out in my experience it is not uncommon for a dyno lambda to read incorrectly. Sometimes it is good to run the car on the dyno at light throttle, so that the engine is in closed loop, and check that the dyno reads lambda 1.0 (14.68:1 AF).
In your case the engine appears lean in VTEC. You should be 0.87 - 0.90 lambda at full throttle. Below 5000 rpm is good, above 5000 rpm is too lean, and above 7500 rpm is very lean. Get the engine re-tuned.
