I agree… past the 1 minute or so engine warm-up the only benefit is warming up the interior and windows (which is why 90% of the people get the remote starter) However letting it idle is not going to do any real damage to a vehicle either… unless you are sitting there letting it run for hours on end… but most remote starters have a time-out period of 20-30 minutes.
Yes, the vehicle will be in open loop during the warm-up period, but regardless of if it’s idling or driving once warmed up it will convert to a closed loop system which will correct the afr. I took a look in my wife’s Jeep manual and it does not say anywhere that it is bad to let it idle for any extended period of time. In addition, if it were really that bad for a vehicle, I highly doubt the factory would have a remote starter as an option… esspecially on a vehicle with a lifetime powertrain warranty.
With all that said, can a mod please move this to its own topic. Although it may be a good discussion in the great Shift fashion, I’d like to keep this thread strictly business related. I’m not asking to delete any of the posts b/c I have no interest in hiding any opinions / facts / beliefs, I would just like to keep this thread clean. Thanks.
