Open loop doe not use any oxygen sensor, it uses only the fuel tables. You do not need a narrowband sensor at all for this.

Details can be found in the help file: http://www.hondata.com/help/smanager/wi ... b=wideband

You should not use the D14 input as it cannot see the full voltage range. Use D10 instead.

Post a picture of the inside of the ECU.

What is the diameter on the intake?

You should not use leaded fuel with a CAT or it will damage it.

High flow indicates it has a CAT.

I would not recommend using this calibration with a catted downpipe as it was not designed for that. IS the 100 octane unleaded, or is it leaded?

Are you asking about upgrading to the version 4 K-Pro?

What content is the analyzer saying you have?

Yes you can do this, but you can run just one sensor and run closed loop with the wideband. ELD (D10) in put is best. You only have to cut one leg of the resistor and can always solder it back down if you want.

What modifications have been done to the vehicle?

What is the part number that is on the ECU?

What is serial number that is on the K-Pro board inside the ECU?

Without the calibration and a datalog showing the issue it's hard to say what it might be.

More than likely anything that triggers the check engine light would cause it to cut out if that is how you have it set. I do not have a test bench to be able to test this. You can try it and see.

I would recommend that you contact HAmotorsports about this.

For this you really should use an ethanol content sensor.
