My Simply Map & 02 Device
Here is my design, it is simply and easy to build. It allows you to adjust the map sensor and monitor the change on the 02 sensor.

Enjoy

RE: My Simply Map & 02 Device
That's simple enough. Is it for a narrow band o2 sensor?

RE: My Simply Map & 02 Device
It appears to me to be a simple A/F meter and can adjust the MAP output. Is P1 used to calibrate it?

RE: My Simply Map & 02 Device
Sorry for not getting back sooner, yes it is a A/F meter and P1 does adjust the Map sensor. It works great and is really easy to build. You can use LEDs instead of the bargraph. You would need 6 green leds, 2 yellow leds and 2 red. The red would be for rich and the yellow for lean and the green is where you want to be.

RE: My Simply Map & 02 Device
Hi everyone,
This is my first post but I have been experimenting for a little bit now with mileage saving ideas. I tried the warm warm air intake and I think it made a diff during the winter months. I have recently been experimenting with a potetiometer supplying voltage to my o2 sensor. I have gained about 4-5 mpg but because I got too agressive with the voltage ( .7-.9v) I think I could have done better. I also have a scangauge that helps me keep an eye on things.

RE: My Simply Map & 02 Device
How are you suppyling that power? Is it coming from the vehicle's 12V system, or is it an external source like a 1.5V AA battery?

H, he's referring to dp's mod. I almost fell for that too. Blush

RE: My Simply Map & 02 Device
Hydrodine,

Does your design control the o2 sensor to allow HHO boost.

I have an HHO generator and a MAP enhancer but am not getting any real improvements so I figure I need to do something with the O2 sensor.

Don't know if I should go with an EFIE or just an extender or use your design.

Thanks
