Idle Valve

[bbs16]

Am running an M4 unit on a 4 cyl BMW e30 m3. and have a map sensor plugged into a T into the inlet manifold to add and subtract fuel according to the valves movements, While it works to an extent would like to try using the duty cycle of the valve to control the fuel compensation. So the question is anyone tried it ?
Thanks Andy.........

Hi Andy,
There is no way you can do this in an M4, the options for fuel compensations are pretty simple.
