FYI. I'm Tom
Cool and concise article. I can accept the statements even without knowing the author and with the "can =possibly" sections. So no debate and points well taken.
I assume LMS, like any reputable tuner would, has tested this recommendation with their vehicles on the dyno and on the street... but that is an assumption on my part, even if aside from the other unanswered CEL question. It may even be specific to the proprietary tune(s) of LMS.
As far as staying in an open loop which is definitely not good... Dave should know in a few minutes of driving if the engine is still at the higher revs of the startup mode at idle when his heater is working already (open T-stat). I think this will answer that question
I'm a bit on the fence in my thinking about it as far as the upper end of operating temp as I think about my first "SHO" summer in Phoenix traffic with ambient air temp 110-125 degrees regularly... is that going to damage my engine, can those two little fans, even in high mode, actually cope with this to keep the engine<195 degrees in stop and go traffic? The next few months will tell I guess.... here in Phoenix at least i would think that starting to cool things sooner might give a longer run in the optimal operating range at least in the summer.
Overall I'm anxious to hear about Dave's real world testing as far as being too cold an operating temp with the colder T-stat... the car will tell him quickly as noted above.
