Wedge air flow meter

[Lesliehedley]

I've just fitted a new air flow meter to my 400SE. The old one used to over fuel the car. The new one runs so lean I can't get the car to idle smoothly. Does anyone know if a new air flow meter needs to be rolling road adjusted to fit the engine? This is the standard air flow meter from a motor factors. Any idea if TVR 'play about' with them before they fit them?

Basically yes and yes it has been known for the ECU to be mapped to the air flow meter. TVRs tend to overfuel anyway when setup correctly as it helps stop predetonation and it gives the car the oomph that we all want. I don't know how bad the overfuelling is but it can be caused by almost any of the components within the system, even down to the temp sensor

Mark Adams is your man to sort this out on a road.
