It could be the HPFP that can't keep up, the plugs need to be colder NGK 1422 gapped to .022" is what I use.
2007 ECU is unique, exhaust pops and burbles can not be programmed, for that one year :(.

Hpfp was the first thing i was thinking! he did have a set of the laser iridium's ! but he swap them back to the old plug's trying to trouble shot ever thing< do you have a part number! and if you're runing a 0.22 we are way off !?!?! and the o7 really dont pop or burble ! why's that! would that cheep 02 have any thing to do with it?

 

On stage 2 the second O2 could be unthread and zip tired away, so I don't think it's the 2nd O2.
HPFP typically show there weakness after a tune demands more fuel from the already weak pump. Also the HPFP typically don't through codes.
Check the DV for cracks and vacuum lines as well

It would be nice to see a data log of the RPM, AFR and fuel rail pressure when this happens.

 

He has a forge blow off vavle ? Would that have something to do with it!

 

Check for leaks and it's a forge BOV or diverter valve? Also, he might want to use a stiffer spring in the Forge

Ha ha Mario. You tuned my 2008's ECU, which as you know didn't come from the factory with the exhaust burble and pops. You were able to tune them in. Was it only 07? I remember how awesome it was to hear them between upshifts and off throttle coasting. Car still runs like a beast, best tune around

As far as the this post is concerned, it sounds like your friends ECU is either trimming fuel or boost because of lack of spark, lower octane gas (detonation protection), fuel delivery (dirty fuel filter?) or faulty HPFP. Also check ignition coils.

Has your friend cleaned his intake valves? They get coked up pretty bad by 100K miles and require walnut blasting.

 

You are lucky man to have a 2008, but it's unfortunate that the 2007 can't be made to have those burbles. I love the crackles and sometimes, even the flames, that shoot out under high boost and load .
I glad you are still loving the Mini and tune

Buddy drop of the car, today at my shop! Thinking its just a cluster of stuff going on! After taking it for a little test drive , I noticed the BOV was sticking open! Along with hearing a boost leaking come from the back left side ! Didn't get much time to start pulling stuff a part was to tired!! Hopefully I'll have more time to dig into it tomorrow! Or this week!?!!

 

I have a late build (10/07) 2007 MCS with a Borla cat-back and my exhaust pops and burbles like crazy (in Sport mode) after my Manic Stage 1+. My tuner (M7) was pretty surprised as well.

 

Mini does some slightly strange things, but it sounds like you technically have the newer 2008+ ECU.

Maybe there a vin split?? Cuz my 07 pop's ever ware I go! Got my tune from m7 as well'

 

My build date was Sept 27, 2007 --- no "pops or burbles" 'til my Manic stage 4. I didn't ask for them, they just "happened". No objections, just an unexpected treat.

 

Are the pops and burbles even with the sports button off? I have seen the higher more aggressive stage have pops even when the sports button is off. The higher stages have more air and fuel moving through the system.

I almost never use the sport button --- don't need it with 300+ WHP!

 

300WHP is a good number for a Mini. I hope to get my new CM to 300whp like my GP. You can really feel the extra 500LBS in the Countryman

so i was out driving around trying to troubleshot why when you get on it from 4k to 4'5k it stumbles then kicks in ,so i was driving around doing 25 to 45 mph range not betting on it taking it easy, low coolant light came on yellow and red. and fan's kick on high. got over and pop the hood and check the coolant reservoir and the coolant leave was good ! got it home let it cool off and want to start it up and the fan's installation kick on. i try'ed to re-bleed the system thinking he mite have did it wrong, nothing fan's still kick and lights stay on. so am thinking the coolant temp senosr mit be bad or maybe the thermostat is bad > but the wired part is no check engine lights or code'!!
and no heat
any idea ware i should start looking or how can i test to see if the senor is bad.


oh yeh i can grab the coolant line and its pretty much ice cold, after being ran for 20 mins

 

As mentioned previously replace the plugs with NGK 1422. Leave them gapped at .022". Stock plugs on a Stage 2 will cause problems after a bit. I've seen it occur in as little as a week when a customer forgot to replace them.

Do you have the DashCommand or Torque app to monitor your coolant temps? Stage 2 should run 185 to 190 degree Fahrenheit in any of the performance maps and 220 to 225 in stock mode.

 

No he doesn't have any thing like that! but one of the he first things he did was put new plug's in! got it narrowed down to the HpFp is going and the senor / thermostat..

got the new thermostat housing coming from Detroit tuned
still looking for a HpFp

 

If you grabbed the coolant line that runs directly under the radiator, that's the wrong line --- this is the "reservoir" line that circulates when "Max Air" is activated, or you put the "pedal to the metal" for a long time. The line to grab runs a little higher and is alongside the driver-side wheel well.

You might also verify the hoses are connected to the correct fittings on the thermostat --- switching these can cause codes.

 

Yeh, ever thing was correct and i grabbed a few different house! its all-most like the thermostat stuck open! it does have 84k ever thing being original!! when i pulled the coolant temp-senor it did not look healthy !!!!! on top of that, i was reading that there was a coolant temp sensor recall! so maybe that had something to do with it or it was its time to go!! and am not sure how my buddy bleed the cooling system< so maybe there was a big air bubble in the system some ware! ether way we have a new housing coming from Detroit tune.

 

I am hurt reading this.... It is possible to swap ECU's from an 08 or higher to put in my 07?? Thats my main reason for getting a tune...

 

Call m7 tuning and see what they say' my buddy called and talk with them last week and they swear up-and-down ' that the 07 does pop and Burgle , his tune is u91 octane map c at 100% !!

 

No doubt... i appreciate that..
