I am intending to buy a Megasquirt II board
I need to verify the compatibility of the interfaces
I have AutoMeter O2 wideband Air/Fuel Ratio Pro-Comp Ultra-Lite indicator with a 0 to 4 volt output representing 10.0 to 17.0 Air to fuel ratio
The output scale is linear
I prefer to keep the indicator
What is the board expecting by design
How to hook the DC output to the MegaSquirt II O2 sensor input?
Do I need to do any modification to the software?
Thanks

Re: O2 sensor - interface
An analog voltage with a maximum reading of 5 volts and a minimum of 0 volts. The curve is defined by the software.Reda wrote:I am intending to buy a Megasquirt II board

Wire the analog output to MS pin 23.How to hook the DC output to the MegaSquirt II O2 sensor input?
