You're talking about using an A/F ratio "bandaid" to compensate for an underperforming and/or poorly designed cooling system? I think I would just fire the engineer who designed the system and the Sr. Engineer who approved it.Stoich???
I was however pointing out that there is far less air-flow at lower speeds so in order to help control engine temperatures, the radiator fans
can only pull so much heat away from the engine at low speeds, so to augment this manufactures can inject additional fuel to help cool the engine.
Not that this would ever have to happen, because this would never happen. Sr. Engineers for car companies don't make it to where they are by designing or approving subpar crap.
Right. You're sorta making my point here. You can't run a car rich to try to cool the CC. COs on a drive cycle will be wayyy above max allowable spec.How so? A cars that runs richer will be less efficient and show up during standard testing, if manufactures
were actively trying to hide that fact during EPA testing then for sure they'd be in deep sh!t.
I would just spec a larger radiator for a few dollars more. Even if it did cost $50 per car, that's cheaper than a recall to put in the radiator that the car should have got in the first place.How would you cool the engine easily elsewhere without increasing manufacturing costs
or the MSRP? Remember even a $50 increase can add up to tens of millions over the
life-cycle of a car.
Well, sorta. The ECM calibration would need to go (again) under approval, which requires an emissions test, which I can assure you won't pass.By running slightly richer during low-speed operations they are effectively passing that cost over
to the consumer without making any changes on the production line.
We've heard this before. I think once you say the "L" word, they stop caring about you as a customer. I'm sorry to hear you're having this experience. As was advised above, perhaps it's just best to contact an attorney at this point.Well, this has now gotten absurd.
I can honestly say that Nissan/Infiniti has the WORST customer service I have ever experience.
For what it's worth, I think this is par for the course across all vehicle makes, so I would just carry on and pick the car that you like best, and hopefully this is just an isolated incident.
I presume you're recording these calls.
