I bought a prosport evo wideband (Bosch 4.9)gauge a few months back and now I'm going to get tuned and need to be able to log with this thing. I have the analog 0-5v output spliced into the ecu rear o2 wire. I already have the rear o2 simulator setup in ecuflash. When I log in evoscan I get crazy readings like 670000 at idle.. I am using the formula 0,05859*x+7,7
which i read gives very accurate readings with my prosport wideband. I have read everything I can find but there just isn't much out there. Wanted to see if anyone has any suggestions or formulas I can try, Thanks.

 

nvm I did some trial and error and found that the formula 10+(20-10)*x/255 worked perfect for me.
