The car is hesitating sometimes when I shift into 2nd and third? (slight yo-yo feeling) Could the pulley have caused this? Is there anything I can do to smooth it out? Maybe an intake or exhaust? By the way the pulley is my only mod. Thanks

 

Try turning off the DSC. With more power you might be spinning your wheels.

 

as it was explained to me, the supercharger, intake, exhaust, and throttle-body are the key parts of the systems that let the car "breathe." Make improvements to any one of these components and you'll see a modest increase in power. However, since each element is mutually supportive of the others, there is a synergistic effect that is gained when all of the components are improved that is greater than the sum of all of the individual mods taken one at a time. Simply put, you need to add a CAI, aftermarket exhaust, and a larger TB to your pulley to really see the numbers you might want.

 

If you are a nivice, and a gamer, the Grand Torismo PS2 game is a perfect reprecentation of how a performance car is built. You beef up one thing, then others lag behind. Do you have the V36 software installed?

 

turn off traction control

 

make sure the Flux Capacitor is on...

 

Once I had the 15% pulley done I noticed a 'loss of traction'

 

I do not believe you can disable the "all season traction control" only the DSC which controls the throttle and 4 wheel braking. It's always there.

 

you might be running too lean. i would go do the v36 if you haven't
already.

 

Why would you say this? What evidence do you have on an MCS that this could happen? There have been a lot of A/F graphs posted on this site and all of them - even with the 15% pulley - showed they were running not just rich but pig rich! On the other hand, if you do have a graph of a 15% pullied MINI running lean please post it so we can learn from this. :smile:

 

Yes, I'd be very interested to know how you know it can run lean. When I had my 15% pulley done, the owner of the dyno shop told me that I'd run too lean with the 15% pulley alone. I told him, since he seemed so concerned about it, he could run my car on his dyno and show me. Do you think he took me up on my offer? NOPE!

BAM! Lean, schmean.

 

DSC/ASC/traciton control has nothing to do with what he is talking about, so forget about that unless traction is your problems.

I agree fully with Redleg's explanation above. It is that synergistic effect he is talking about, the pulley makes your car want to suck in more air (and fuel) so the freer flowing intake will make it feel great, and then those gases want to exit, a different exhaust can handle the exit better. I haven't had a ported TB because it's expensive but for now I recommend you go for the Pilo intake. For the price and quality it brings to the ride, it's very well worth it. I like the gains of the exhaust (Really frees it up) but I put that second simply because of the much higher price.

 

Anatranik,
Before you state that the DSC has nothing to do with his problem why don't we see if he tried it and what the result was. With only a pulley and intake I always turn off the DSC before driving as it will give exactly the response he describes. No fun at all.

 

Right after my car was modded I went to take a buddy for a demo spin, forgot to turn off "Grand Turismo" mode and had the exact same thing happen.

Sure thing I'll wait for his response. The only thing that makes me say it wouldn't be the DSC is because he says this feeling happens when shifting into 3rd as well. Especially when a pulley is your only mod, why would you be losing any traction and activating the DSC at all into when going into 3rd? If you're not spinning your wheels, going into any skid or anything like that, DSC doesn't affect anything when it's just on but in the background doing nothing, at least for MY car, or so I thought?

 

It's not the DSC. I think it's a stumble and I didn't have it before the pulley? When I shift into 3rd gear there is a slight hesitation.

 

Has your ECU been able to adjust to the new pully?

I have no idea if my ecu adjusted to the new pulley? I'm supposed to have the v36 version according to my salesperson. I didn't think I had a stumble(hickup) before the pully, but maybe it's more pronounced now with the extra power? Anyone else have this experience? If you have any suggestions to fix this I would appreciate it. Thanks

 

Tiger, what's the rpm you are changing gears at?
Have you tried different clutch release teckniques?
Just curious.

 

I drive aggressively, I shift at about 5-6000 rpm. First and 2nd are ok, but when I shift int 3rd I get a hickup. The car hesitates for a split second. From what I have read in other posts, the stumble usually happens in first gear? Am I the only one who gets it in 3rd?

It's definitely the DSC. You MCS is now considerably faster and the DSC is coming on thinking you losing control (because you're accelerating so fast) You can shut the DSC off, (and you will no longer have that problem) or you can squeeze the throttle and keep the DSC on.

Tiger, I see some here think your problem is the dsc. Have you tried duplicating the condition both ways, with the dsc off and on?
just curious.

 

i think tiger1 already tried it without DSC...

I would look into ECU upgrades since you say you have v36. You can
doubt me all you want, but i still think its your fuel mix...otherwise it
should consistently give you a smooth response. Are you on
winter gas? How many miles do you have since the install? If you're
over 400 miles, chances are your ECU can't compensate enough to
adapt to that new environment.

As much as I would hate to do it, if i were you, the first thing i would try
next would be a bottle of octane booster in your next fill up. see if that
helps, if yes, then chances are its your fuel or your fuel mix. Ive heard
some nasty things about octane boosters eating away fuel lines and
causing problems in the injectors on other cars so make sure you want
to try this route before you do it.

I would definitely get your car dynoed and prepare to get a ECU upgrade
so that you can run regular 93oct fuel without hesitation.

What's ironic to me is that d-mini-ero seems to be the only one with
an ECU upgrade on 15% pully. 15% pully + ECU upgrade should come
together if you feel any sign of hesitation. :???:

wish TurboXS made UTECs for our MCS's...

 

I already run 93octane. What should I be using(octane)? I already tried turning off my DSC and it didn't work. This is happening to me when I shift into 3rd gear. Instead of having a smooth transition I get a hick up feeling. Has anyone fixed their stumble/yo-yo by installing an intake?
