Anybody who has an MPI and is considering an LCB might be interested in this. Currently the Lambda sensor in the standard exhaust manifold is installed in the common part of the manifold. The LCB I bought (Janspeed) has the Lambda sensor installed in just two of the legs and as such does not see the third leg exhaust gasses. This causes the emmissions to show too much oxygen in the exhaust.
A simple mod is to relocate the Lambda sensor further down the exhaust to the common pipework.
