I have the alta pulley and alta intake installed on my '03 MCS, installed at 10000miles and now at about 12000miles, and everything seems to be great. But when I accelerate around 2700RPMs I feel a slight stutter and jerkyness. Once I mash down on the accelerator it goes away. Has anyone with the same set up i've got experienced this?
Its not that big of a problem but I just want to know if I am in any way hurting my car since I am a college student on a tight budget.
All i have is pulley and intake.....and tinted windows and 4 aux lights.
thats interesting... im very interested in getting the alta products myself.
is your problem still happening???
i have a very uneducated opinion here... it might be possible that by adding a new exhaust system might help this.. ive heard from other people that when they installed an exhaust the yoyo went away..
how many hp increase are you getting from the intake and pulley??
Exhaust didn't cure my yoyo
Alta intake didn't cure my yoyo
Both did make it go away for about 100 miles.
I'll be doing the pulley soon as well. I've given up on MINI fixing the problem.
I have read posts where any/all of these mods has cured the problem. Lucky them
hehe bit of a mystery hey
sorry to hear that your car still has the problem.. in my car i dont find it that annoying anyway. the rattles anoy me more
are you planning on doing an ECU upgrade also?
if so.. who would you go for?? you have a few different aftermarket mods from diff companies.. does that matter when doing an ECU??
I've gotten used to it as well. I guess what really bothers me is that some don't have it( jealousy ) and I have this itchy feeling that it's a symptom of somehting that is costing me HP. That REALLY bothers me.
No ECU at this time. Money for one reason but mainly none up the upgrades I've read about here and elsewhere inspire me all that much. Better things will come and hopefully for less than $600, yeesh
I have the Alta Pulley and Pilo Intake. You need to update your ECU at the dealer with the newest version # 36. This will give you smoother acceleration and make you MCS quicker off the line. This is the latest software which is used to correct yo yo and stumble problems. It works great I just had my dealer install it the other day. Try it you'll like it.
I have the alta intake and pulley. It sounds like you are describing the infamous "yo-yo". I just had version 36 of the dealer software installed yesterday. I have not had a chance to do a ton of driving, but the yo-yo is still there. First impressions was that it was not as bad, but time will tell. The car does seem to drive a bit smoother with the v 36 software.
Happy Holidays,
Chili Red & White MCS. Alta 15% pulley, Alta intake, GIAC software coming soon..
i had no idea that the MCS had upgrade software.
think i might have to get in touch with the dealer and see what they have to say... would we have it down here in Aus?
COOPERSPEED. how do u find your alta pulley and intake combo? noticably good?
The combo of the Alta intake and pulley make a huge difference in the car. I installed them both at the same time so I can't comment on how they work with one or the other, but together they work great. Much quicker and the sound of the intake and supercharger is oh so sweet. GIAC has been using my car to help develop software for the mini. There is definatley power to be gained through software tuning.
