is it dangerous to drive with a turbo i0n the winter, i've heard that if the temp gets below 40 degrees or so that it could hurt the fan...any one know anything about this theory?

 

wont hurt any fans or anything, because the turbo is like 1200° anyway...

 

that makes sense...the person told me that because the turbine spins so fast that Ice could build up...but being so hot it would be impossible.

 

Your turbo will LOVE the colder ambient air... especially with a FMIC.

 

ICE ROFL!

yes it will be dangerous!! tires spinning in every gear... turbo love the cold!

you will gain as much as 15whp or more compared to 90 degree summer day

 

wont the cold, denser air cause him to run lean??

Exactly. You will notice every winter people blow their motors cause they had their setup tuned in the summer months. One reason I dont like certain standalones....need either 2 maps or get it tuned twice per year.

 

hondata realigns itself based upon the seasons doesn't it?

 

I drove my car through last winter. When there was not snow on the ground it felt really strong. I tuned my vafc hack in the cold as well and found it was too rich once it warmed up.

 

What about cold strat in winter. Is it harder to start comapre to before it as turbo?

 

Im running the vafc hack which is know for having hot/warm start problems. Well here is the weird thing, on the super cold days or even just cold days it would start rediqulously fast, like way faster than a stock Honda. The second the key hit start the engine fired to life, you would not even hear it crank for a split second hardly. You just turn the car on, bump the starter real quick, and the engine is instantly running and idleing perfectly. It would freak me out and I still cant believe it. There is no way any other car engine can start up faster than mine does on a cold day. Just another one of the weird characteristics of the vafc hack.

i don't think so.. with n/a setup i turned fuel pressure up for the winter and turned it down in spring (my car was tuned in summer). after turbo, i might get it tuned for both winter/summer.

 

Actually, if you run closed loop O2 feedback you shouldnt have any problems. But, unfortunately not everyone has the capability to run a wideband o2 setup in closed loop form---I know EMS does it, but not sure on others.....hondata doesnt, but Im sure some tweaking from their techs and it could be possible.

Most people will just tune to open loop and have their maps run like that. You could turn up fuel pressure like stated above, but that if just a bandaid if you ask me.

 

i wonder if i even have to worry, in s cali the weather does not really change dramatically, its always around the same, except some really hot days where i shouldnt drive anything period...

As long as u keep your O2 sensor you wont have a problem.

 

Sorry to thread jack. I was just about to start a post on different maps for hot and cold and I saw this I'll post here instead.

I'm already noticing that I run pretty rich when the weather gets a little warm and I'm not even talking that great a hike in temps either, like summer and snow. I tuned the car one evening to pretty much the way I want it and next afternoon the a/f goes down to between 10.5 - 11.5 when its like 20 - 25 deg compared to 15 - 20 deg C at night, so I find myself readjusting the fuel trims all the time, day and night its ridiculous! So I'm starting to get a little concerned about tuning the car good right now and come winter I'll be freaking lean!

How does standalones, if any cater for the drastic changes in ambient temps? Does it recalculates itself or does it need two fuel and timing maps, 1 for winter and 1 for summer and will switch accordingly once a temp drop is detected?

 

I am also curious. Should i have 2 diff maps for winter/summer or will hondata adjust according to temp?

 

Even with Hondata would'nt the system still run in closed loop with the stock O2 and the stock ECU?

Is there any reason why you wouldnt want a street car to run in closed loop?

You dont want a tuned map to run in closed loop if your using a narrow band O2 sensor.....they are just too inaccurate.
