That output is fed back into the O2 sensor wiring where ROM Editor or HondaLogger convert it back into a precise air fuel ratio. You can make an adapter (using the plug off a dead O2 sensor) that connects the 0-5V wideband output to the stock oxygen sensor plug. Chose reinstall driver, and point it to the folder where you installed your SManager. *Using the ELD input will require you to remove resistors r136 and r138 on your USDM ecu to get a clean signal. Values in column 4 should start to be recorded as you move to a higher lower vacuum with more load column 5.

Make sure the half moon notch on the chip faces toward the ECU plugs and then solder into place. ps: i removed your pictures in your first post since it has nothing to do with this problem and it takes up tons of screen space lol Also make sure Disable o2 heater is checked if you are not running a factory o2 sensor. Check out some samples from the hondata s300 course below. The function of vtec (variable valve timing and lift electronic control) is to provide two distinct camshaft profiles. Scaling for AEM. Unscrew both top and bottom lids from your ECU and set both covers aside. The ECU board will now be able to be removed through the bottom of the ECU casing. Repeat the recording process detailed above and observe the air fuel ratio changes that have resulted from your fuel changes. It you have a turbocharger, set the boost value as low as possible - preferably zero. Thoroughly clean the ECU casing and circuit board with a quality electrical parts cleaner of any debris or remaining solder flux. 4. f]6lUdWy.
