[Diy_efi] analog to pwm

[Bevan Weiss]

That's easy.
Just get a 5V triangular or saw tooth waveform generator, and apply both 
signals to a comparator.
The output will be a PWM waveform.
Adjust the triangular/saw tooth frequency to adjust the frequency of the PWM 
output.

If you're looking for a circuit, and which parts to use etc etc then I'm not 
going to tell you that info.  You shouldn't be trying to convert the signal 
if the information that I've given isn't enough for you.  If you honestly 
have no idea about electronics then you shouldn't be playing with whatever 
you're trying to make up this circuit for.  Get the basics down first.

Regards,
Bevan
