Hi, found the solution. I've discovered the egr sensor has a built-in conversion ratio of 8, so if i use your circuit I'll obtain a conversion ratio of 16x8, it'll suit flawlessly my application.

Hi, I'm trying to create an input of max 500Hz to a Link G4 to set a "max speed limit" (to run on a safe boost level for now) of the turbo shaft of 92,044 RPM on a 14 blades Borgwarner. If I use your circuit my output frequency will be around 1350 Hz wich is not readable by the ECU. I'll need a divider by 50 from the original turbo frequency to the final frequency entering the ECU: 92,044x14/(60x50)=around 430Hz. How can i wire the two frequency dividers toghether? And why did you put resistor on the supply I'll thank you in advance, any help will be much appreciated. Salute from Italy, Federico.
