Gents,
Been working on lower temp thermostat for long time now.
Nothing is available, either 80° or 55°.
In California during winter times I have driven with 55° t stat
on our old E46M3 and the warm up time was extended indeed,
fuel consumption was also increased by a bit so additional tune
is required to trim the fuel ratio.
I am close to start offering 70° solution. The benefits will be around
town and also track, with lower temp t stat one can "Buy" more laps
and what most people do is time trial.
By lowering the opening C° point the heat soak will be delayed by
significant amount of time. 90% pips here owning M3 do use their
cars for time trial fun.
Race cars means they are being towed to the track not street
driven for time trial 15-17min for example at ButtonWillow, will benefit
from 55° or 70°
At 70° will not require for re-tune for those have stock tune also the
check engine light will not be bothered.
Will see, I need to do few more test may end with 68°
Regards,
Anri.
