Smoke over 4K rpm
My Giulietta is remapped and I noticed that with dna on Normal, it is very hard to see any smoke coming out of the exhaust, which is a good thing, but I noticed something on a high rpm.
There’s this road I do every day coming home from work where many times I pull a 4th gear up until the redline and once it gets around 4K rpm, I start to see some smoke coming out.
So I’m thinking that in those rpms, the need for air should be greater and since diesel runs very lean, if the diesel input increases linearly and the air input at some point is not enough, it will result in a richer mixture and consequently start producing smoke.
Could this be the case?
