Dyno Tuning?

[riceline]

Just wondering,

When a tuner is tuning your car. They are doing it for the particular atmospheric conditions at that time.

After reading a few of the recent posts. They have said that in cold weather your car is more prone to “ping” due to the denser air. But this is also true in hot weather.

If this is the case. When is the best time to have a car tuned? What can be/is done to overcome this?

I always thought the colder the air the better.

On a cold night should a person run Less boost than on a normal day.

Thanks guys

anyone?

I think you have it the wrong way around...

best way to over come is probably to have an inlet air temp sensor and a computer that can compinsate such as wolf does

[bmxwrx]

reducing inlet temps is a way of preventing pinging, thats why you get a big FMIC

Got agree here, colder air is much better and prevents pinging.

Hotter air is less dense....ie

..anyway, regardless of the density, i think it's the higer temps that cause the pinging.

...but back to the dyno subject....i had mine done ages ago just for fuel/air ratios and they were spraying water onto my standard intercooler....later i though that was a bit stupid cause i don't have a spraw when on the road...sometimes i think they just wanna improve their rwkw reading to make you think they've done a good job (not all of course)

yea i would be interested to also note what people think about tuning in regards to a SAFC. Obviously you want to get the most power out of the car by leaning the mixture out but at the same time especially in canberra our temps change dramaticly. eg summer up to 38 + days winter nights that are anywhere from -6 or so. Would you generally want to get it tuned up once every 6 months say to get the mixtures right or do you generally just leave it a little rich to be on the safe side ???
