hey guys, trying to detune the car for winter. tired of constantly braking loose in cold dry winter weather. as well as with all the snow on the ground. I'd like to keep AFRs in check to help mileage. I'm going to reduce boost to minimal to help. My question is how much timimg should I pull to reduce power without adversly affecting drivabilty. And yes i know the car is there for driving and I do take advantage of the power. Just thought it might be a bit safer to drive not having to worry about the tires contantly braking loose.

Yes the right foot modulation technique works too.

 

You answered your own question, use your right foot.

Pulling timing to make a car less prone to wheelspin in weather conditions is outright backwards, really just a silly idea.

By keeping AFR's in check for milage you mean leaning it out? that makes more power and is more dangerous than being slightly rich....

I think your safest not in the evo

 

find a stock map and stick it in with low boost.

 

no, meant I didn't want to richen it up to produce less power only to use more fuel in the process.

 

Put snow traction on and stay under 3k, you shouldn't have tractions issues

 

why go through so much trouble...if you got acd just press the awd button twice to put it in snow mode(just what the post above says) lol...seriously i wonder what your current map looks like

 

 

Then your not going fast enough

I'm not having problems, I thinks its just worth a few minutes of my time to flash a lower performance map onto the ecu to help prevent potential issues from unneeded power during the winter months. Guess caution and the evo don't go together for too many people around here.

 

I think lowering the timing as well is a bit extreme. You are already lowering the boost, which means that in many cases you are already going to have less power just by doing that.

Plus if you are lighting up the tires more than likely thats your problem right there (as said above). Get some proper tires for the conditions and I'd bet that even without detuning you get grip back (assuming you aren't just flooring the car on ice/snow which would just be stupid).

 

No, that's not it at all.

It's the fact of the matter that the bulk (definately not all) are capable of just driving slow, instead of detuning our cars to be safe.

The fact that you are seriously, actually, honestly, researching de-tuning your car via adjusting timing and fuel to make it "safer" to drive in the snow boggles me. Then again if thats your car in your avatar I don't expect much.

I'm really confused.... why the heck do you need to alter the fuel or timing maps? You're lowering the boost right? That just puts you in the lower load cells of your maps, which should already be perfectly fine.

You want less power? You lowered, the boost. Done.

 

Not really , I just drive smart in the snow. I leave the fast for the track.

 

I have to agree this is just a bit much, at this point I would think the best thing you could do for the winter time is hang your keys up.
Just not thinking to use the traction control button is kind of a big one for me. I wish it snowed here just so I could use it.... I look at it and think about it all the time in the winter

 

just run it on gate pressure (about 11PSI) that should be plenty slow enough. as long as your tuner did the maps properly there should be no problems with AFR (otherwise just log a WB).... eg my car made about 25-30% less on 11PSI as compared to 20PSI.
