Hi Guys,

i have been wondering for a short while now about getting this RaceChip,

it seems to add a decent amount of BHP and Torque and i like how you can fiddle around with it on the Smartphone app and can decide how much HP you want ect like Shmee150 did with the Panamera.

just wondering if anyone has any experience with this and if its okay to use and won't cause any damage to the engine.

sorry if i'm being extra cautious

cheers!

I am working for a big corporation that supplies many important engine parts for almost every customer on this planet in the automotive industry. From that standpoint and the experience with engine testing on test beds and so on, I can only say: Don't tune your engine with something like this. This is not the way to "tune" an engine. A lot of the components as well as the oil supply are M4/S55 level in the M2 - so they can withstand higher pressure - but this is not the way to go.

If you have a manual M2, please note that the transmission is only designed for 450nm, so even the regular overboost is normally too high for the gearbox.

If you want to have more power, please ask or request that from some people with a long lasting experience in the game, like Tuningwerk, Lightweight or someone in your area.

Hello,

thank you for the advice, i have a DCT but i will most likely give these companies a email or so.

thanks for your help

1 last question, can you recommend some good aftermarket brake pads? i'm not really wanting a full brake replacement just pads which won't wear after 30 minutes.

If I remember correctly it's a two sensor piggyback and to a large extent it's similar to the Dinantronics unit both in the type of piggyback and its bluetooth capability

Personally I would not go for it at that price. Might as well go for a multi-sensor piggyback like the JB4.

Generally speaking according to what I've read around this and other forums, piggyback's on the M2 have been a hit and miss. If you're just looking for a little bit more power I would recommend a catted DP

You can try the M performance brake pads. I have only heard good things about them.

They are currently building a new headquarter. Mabye that's why! Normally, they are very responsive!

Sorry to thread jack but this is the first time I've heard of this. Are you suggesting that any sort of tuning done on the M2 requires the DCT tranny in order to maintain reliability? Seems somewhat odd since most of the time these types of components are over-engineered from the factory.

Krizze,
To keep things on track I'd recommend a JB4 if you want a piggyback unit, although people have had mixed results with this setup in general on the M2 platform. If you really want a tune, I would go for BM3. Otherwise just add in a catted DP from Fabspeed and call it a day

Sorry, it's 470nm.

See here: Transmission is the GS6-45BZ by ZF.

Please click on "Technical Information". It's the same tranny that the 1M had with a few modifications.

They could have opted for the GS6-53 that could take 600nm...but they didn't.

Too complete your question: yes, if you have a 6MT, please stay away from mods that increase nm or pressure on the gearbox as this can affect the drivetrain in general (in a bad way).

Looks like you're right! Very strange that they went this route. Seems that the DCT transmission can actually handle a higher load (520nm) as compared to manual. Meaning that tuners wishing to run a stock transmission should probably opt for DCT instead of MT. Sad day...

DCT can handle even more: http://www.getrag.com/en/products/produkt_detail.html

Up to 700nm.

Very good Pads - great initial bite and last on track. But they squeal like hell around town once warm (not roasting hot, just used a few times).

I have looked into Racechip, they've been around a long time and offer an engine warranty (but check the terms and small print closely).

Even the JB4 gets mixed reviews on the M2 - I just don't think the engine enjoys tuning boxes as much as the Mx35i/Mx40i cars.

So if the limit is 470 and the M2 has 465 peak torque, does it mean even a catted DP is a bad idea for a manual?

If we're going by spec alone, it appears to be so. However, people have been tuning the manuals for 500nm+ without issues it seems. I'm still weary though - I assumed the MT was rated for 600nm+ from the factory.

Hmm, the M2 and the 1M share the same manual transmission

Anyone know what the reliability is on a tuned 1M with MT?

I thought this was same box as f30 m4

Wait a second here. 470 nm is about 347 ft-lbs. BMW's overboost is rated at 369 ft-lbs. Are you saying that BMW's overboost alone exceeds the safe limits of the 6MT tranny in the M2? So the factory not only doesn't engineer some head room, it markets a stock car that exceeds safe limits?

I have a very hard time believing that. No factory in its right mind would sell a car that close, let alone that much over, the ragged edge.

It's also strange that Dinan, which matches the factory warranty, does not seem to be worried about this. Their big turbo kit claims 458 ft-lbs, more than 100 ft. lbs greater than the supposed limits of this tranny, and Dinan has always been relatively conservative as BMW tuners go. That would be simply crazy if your warning is accurate.

We are always talking about the gearbox, not the engine or the pressure. The gearbox is quiet "under dimensioned" but maybe can still keep up with the stock setup. The M2 is not that old of car to have a final conclusion, we'll see in the next few months if there are cars with (manual) gearbox problems (modded) coming up.

[tstafford]

IMHO (just mine) - In my limited experience so far with the M2 torque hasn't been the limiting factor on performance. I've got plenty more work to do on improving rear grip. I'm certain that the rear grip is where I'm losing time. In addition to tires, I think suspension work will likely yield more bang for the buck when reliability is factored in. I don't envision tuning this motor.

Which manual is in the M4/M3??? I just assumed it was the same 6 speed.

Part numbers are the same but that wouldn't make sense especially since the M3/4 puts out more torque stock than the MT is rated for. Makes me think BMW is doing some voodoo magic before actually shipping the car with those transmissions in them.

Perhaps they're modified in some way? Or BMW is betting on them not failing...
