Once the engine is warm enough to go into "closed loop" operation, mixture
control is mostly dependent on the O2 sensor.  Closed loop seems to occur
around 35C. There is some ignition timing compensation on Digifant but no
one will notice. That said the 87C stat is the best choice for a number of
other reasons.

Your engine management system is designed to run at 87.  If the 80 degree
stat is used, the FI will be constantly adjusting for a too cold engine with
a too rich mixture, wasting gas.
