GruppeM C/F Air Intake kit.........
Discussion
How much is the kit?
There are other companies that do near the exact same thing.
As for custom vs generic remap - I think you'll find that unless a modification is carried out which is extreme and outside of the parameters of the ecu there is little difference between a custom and generic remap.
Custom remaps are only really worth while if something like cams and a carbon fibre plenum is carried out.

They are very expensive, perhaps too so, and yes there are other companies that do similar.
I would not let a generic remap near any of my cars, Every engine will tolerate different amounts of timing and leaner/richer mixtures. Every map should be tweaked to that specific car. Its not really a case of getting more power, much more about safety.
I do however agree that you are going to see more benefits of the custom remap with more major mods than just an airbox.

They are the best made and best sounding air intake kit i have come across..
Performance improvment is minimal, however, if you did get the car custom remapped (none of this one chip fits all rubbish) then the benifits are very good

Thanks for the advice, Charlie. Have you actually seen one installed and run on a car on your dyno??? Custom mapping would be the way I would go (no generic maps for me thanks). I realise that done in isolation, the performance gains are marginal, but wondered what I could expect if combining one of these with the GruppeM Ti exhaust and a custom remap?

As it happens, I saw one on an E30 M3, this particular car made 7.5% more power with just the box and a play with the fueling (so, no remap essentially)
On the newer M cars, i would'nt like to say. Not had so much experience of them.

Out of interest how much is a remap compared to an off the shelf 'chip'?

Depends totally where you go, there is nothing wrong with an off the shelf map as long as when they put it on the ecu, they then tweak it to the car.
Remaps on BMW's are not really my business, so i would have a word with the guys at AMD or DMS.

When you put these on the E30 M3 you do away with the AFM and go for a TPS set up, removing the AFM is the best power gain, the CF plenum is lighter than the alloy one and doesn't tend to put pressure on the throttle body gasket plates.
Its a full Alpha N set up usually for management. (you can get the CF plenum that maintains AFM but that is for looks only.)

Yes, I remember now, that was exactly what that car had
. Do so many cars its hard to remember

You can run a Motec with Alpha-N, basically if you fitted a proper C/F plenum and intake trumptet (2k euro) with Alpha-N you would have the same set up as whats fitted to the M3 CSL.
My understanding (somewhat limited) is that Alpha-N mapping uses a TPS (throttle position sensor) instead of the MAF. Can this be operated / linked to the standard ECU running a custom map or is a different ECU required? Also what are the normal road manners of an Alpha-N setup - I've heard that it's more suited to race engines than road use?? (even though the CSL uses it perfectly well!)
