Was on back order and so will pick up next week and fit then get my car over to Hayward & Scott to sort out the rest (axle back).

Very strange. If the car really is making more power in M mode a bunch of people here are going to want to know about it...

See around the 2:35 min mark re M button ... Changes mapping, more power

The M button changes throttle mapping only and does not give you more power. You will get more power on full throttle with overboost with or without M button depressed for 7seconds only!

Changing the throttle map makes the car feel sharper and more responsive. A lot of so called tuners change the throttle map only and then tell the customer that they now have more power.

The only M car I recall that the M button gave more power was in the E60 M5 and E63 M6

So M boss is speaking out his a-hole then?

Probably a miss quote perhaps?

I am having my car on the dyno this week so can find out for sure whether the M button provides more power or not!

LotusBoy · 03-29-2012, 07:35 AM

I think the M-boss means "More power in M mode than in normal mode for the same pedal input". Tuners found no significant power difference testing the 2 modes on the dyno ... It's a lot of marketing talk, IMO. Like when he speaks of different maps, he means throttle maps, not engine ECU map ...

hey, ian - can you start the dyno in M mode first and go into non-M mode? Zuzu's result was different to other results posted from reliable posters. I think his results are to do with the cold engine - boost on non-M mode seems to be on the low side.

The technical director in M actually stated that the ///M button only change throttle mapping and closes the waste gate, i.e. no power change.

Running in M mode first will avoid any issues with cold engine.

Fitting the N55 midpipes tomorrow morning and while I am at it, will sort out some braided hoses and uprated brake fluid, after easter will drop off at Hayward & Scott for a custom axle back system to finish it off......

Cool, any chance you will do a pre- and post- dyno? We got some deltas for both the Berks and the MadDads, would be cool to get the N55 mids in there as pretty much those are the 3 main choices for mids.

Afraid not sorry as a mate and I are doing the work in his garage and not at a tuners......

Don't understand what you mean by " cold engine"..

The engine was at the optimum operating temperature..

The it threw the previous hypothesis out the window from the other thread. Also noted results from yesterday's dyno day which confirms the mid pipe gains at 6-7kw.

Drillslinger · 04-03-2012, 04:12 PM

I pick my N55 mids up on Thursday. What are y'all doing with your std parts? Is there much of a resale market for N54 mids out there?

Thx

If I were you I would just place them in storage...the stockers have catalytic converters which makes them extremely expensive compared to the N55 mid pipes. Save yourself the hassle if you ever want to go back to stock.

Drillslinger · 04-03-2012, 11:39 PM

Lol, I was afraid someone would say that. I'll just stash it next to my std MINI exhaust that's hanging in the garage and HOPE that Uncle Sam is lenient on weight allowances when we move back to the states

Mine is on back order from BMW. What are your thoughts now that you have had the midpipe on for a week or so ?

Keep ypur stock mids w/cats bc new ones are like $2K USd! You might need them depending on the state you go back to.

Drillslinger · 04-08-2012, 04:21 AM

$2k!! Holy crap!

Thanks for the heads up Dack

Well worth it for the price mate, on start up the tone is deeper for sure, also once the revs settle it is deeper.....

My mate who is a tech helped me fit (also the braided brake lines) took it for a good run while I hung back, well worth getting someone to do the same as the note from outside is totally different to what you hear from the inside, also the vids shown don't actually replicate, he had some popping on gear changes and the note is loud on WOT, not what you expect from a oem system, also the improvement in back pressure appears to have improved the throttle response with the M off but it's not a massive difference but for the price I wont knock it, as for the drone, its made a nice improvement all round.....My misses has even noted it on start up and giving it some beans.

Next the H&S custom axle back to finish it off and that will do me as I have no plans to remove the main cats unless someone does 200cell sports cat downpipe replacement.
