I installed a Wideband O2 sensor on my 60 Tohatsu and the test results were surprising. for the ones that aren't a where what a O2 sensor does here is a explanation.

(A wideband O₂ sensor measures how much oxygen remains in the exhaust, allowing you (or the ECU) to determine the actual air‑fuel ratio (AFR) across a wide range—not just rich/lean like a narrowband sensor. It outputs a continuous 0–5V signal that corresponds to AFR or lambda, giving precise insight into combustion. This is why widebands can accurately read mixtures from very lean (20:1+) to very rich (10:1).

Raw data
Stock ECU Stock Air Box 11.9-12.4 AFR
Flashed ECU Stock Air Box 11.4-11.7 AFR
Flashed ECU Velocity Stack 11.1-11.4 AFR

more customer feed back on the Tohatsu Velocity stack

(Don’t have a tach but can tell the boat is more peppy, interested in the tiny tach and mount when it comes out. Increased me about 2 mph hit 47.7 with a stock 50 tohatsu. Highly recommend the velocity stack was a good purchase)
