Doesnt any problems feeling as if the turbo is not even working? Once in a blue moon when I get on the gas it feels as if theres no turbo in the car, wondering if anyone has the same problems and what it could be? It happend a few miles after I installed the alta intake and after i installed the alta pnp ecu. Any ideas?
Thanks

I've moved this thread because it's related to modifications.

To assist, have you done the obvious and unhooked the PNP Alta ecu to see if you're producing boost again? If so, re-read your Alta PnP ECU instructions and re-install.

 

Yea I have done that, but the car also felt turbo-less before the ecu (only mod at the time was intake).

 

Its possible you have a vacuum leak. Did you install everything correctly? What RPM are you reving to? Most importantly: Do you hear the Turbo spool?

 

I've felt that too. I think it's heat soak. I now have temp and boost gauges, will keep an eye on it.

 

I ran the car stock at California Speedway drag strip this weekend. I was shocked that I had a good 60 foot twice at 2.25-2.3 but only ran 15.8 and 15.9 at 83 MPH both times. It was 80 degrees and I was in the staging lanes an hour before each run. I felt like the car ran strong the first 1/16 and the rest it just died out. It felt very slow as opposed to driving it on the street. I was thinking heat soak because the car was idling on and off as I moved it up in the staging lanes. I know it can't be driver because I have an R56 Cooper S auto and my 60 was good so there is nothing else I could have done.

 

Quick fix, Put the car in neutral while you're in the staging lane and push.

 

Theres nothing i installed because it did it when everything was factory =\. The problem just worries me and wanted to know if I was the only one who was experiencing the issue. I do not hear any turbo spool when the problem happens just engine =(.

 

Turbo lag?

 

install the intake, then if nothing is heard you definitely have a problem.

 

the car could be broken. the first R56 i drove was totally broken. it was like driving a cooper...lol just kidding guys... no but really it had no get up and go. I told the sales gal that i think something was broken on that car...she was like no no no it's brand new. it works perfect....a week later she told me the car was in fact broken and wanted me to drive another one. they never told me what was broken. but it sounds like the same thing.

 

I think you should remove all of the mods and take it back to MINI for a service check-up if it was happening before you started tinkering with the car. I think it's safe to presume the stock parts you removed weren't the problem and MINI will not honor a warranty issue with the bolt-ons you have. A vacuum leak seems like a good first possibility to explore

 

See discussion at MINI2.

I have had this problem a couple of times myself. I think the car is getting too much boost and the ECU freaks out and shuts the boost from the turbo off for a couple minutes. No big deal, all you have to do is wait or turn the car off and restart it. I noticed this usually happens when you boost up too soon in a higher gear that you should really be in. For example cruising in 5th gear when you should be in 3rd or 4th, then hitting the gas and the boost jumps up. Now that I have changed that driving style it never happens.

 

Ahh. Thanks for the possible solutions, the ECU freakout sounds reasonable because it never has problems driving like a human being lol.

 

It sounds to me like its probably just massive turbo lag since you cant hear the turbo spool. Now if you heard it and it was still now going anywhere, that would be a problem.
I don't mean disrespect but have you driven another turboed car? Its quite different to drive then an NA car.

 

In our case, it feels like the bypass valve is stuck open. No boost & no power...

k

 

So can you hear the BOV "Psssssssst" when you shift at higher RPM?

 

When that situation happens you know right away, because there is no "Pssssst" noise when the blowoff valve sticks open.

 

Do you have a boost gauge yet? That would help a ton in diagnosis of this (and other things as well!)

Also, when does this happen? Sport engaged? DSC on?

 

um...yea? That was the point I was getting at.

 

I've started tuning our shop car and noticed a weird behavior, if you alter the map and tmap signal in such a way that they don't agree, the car will go in to a fail safe mode and stop making boost. But it does not show a light on the dash when doing this. The only way to verify is with a boost gauge. When you restart the car the boost will come back.

Not sure if your issue is related, but it is possible for the car to failsafe without a OBDII code.

 

thats what was happening on my car with the pnp on. after a lil while the boost would come back. but i eventually got a cel and it stayed on for a couple of days so i removed the pnp and returned the ecu to stock and it reset after about a day of driving. so im returning the pnp and im getting a full alta setup, intake, btubes and the intercooler. when i can get the money i will add the downpipe and the pnp last. hopefully the ecu tuning will have all the cel bugs squashed by then .

 

Are you referring to me? I do have the boost guage. It did not matter if I had the DSC on or not. It has not happened to me in a long. For what its worth I get the same amount of boost with or without DCS, I know you said you were not getting full boost with it on.

 

That sounds exactly like what is happening.
