Seeking CSL knowledge.

You are correct. The exhaust valves are different but the intake valves are the same according to realoem.com. Refer to parts 6 and 7.

CSL's valve train:

M3's valve train:

Thanks for the help. :thumbs:

Sorry Max, I got the info mixed up between which valves were different

[///Max]

As far as i know it's only the exhaust valves that are different. It's best to check realoem.com then. :thumbs:

Will do. Thank you sir.

Ok so intake, cams, Alpha N, SMG software and engine CSL software, I got it!

I was told that the intake valves are different and would need them to have the cams run properly. So I was planning on changing those. I didn't know if the exhaust valves are different too. Are they? If they are, I might as well get them too.

Thanks.

install intake + camshafts

then install Alpha - N and CSL engine software which has a totally different mapping for the engine compared to standard M3, due to the fact the CSL camshafts are longer duration.

Will you change exhaust valves too?

Sweet! And yes I will be changing cams to CSL cams and CSL intake. So SMG and engine ECU software, got it.

When you say engine ECU software, are you referring to the Alpha N software? Just wanna make sure we're on the same page.

Thanks.

I you bought M3 CS then you'd only need engine ECU software assuming, you changed the camshafts for CSL ones or Schricks 288 / 280 and SMG ECU software, that's all. :thumbs:
ABS algorithms are totally different for CSL and CS - don't do it.

Ok, so as far as software upgrade from an M3 CS to and M3 CSL I will need:

SMG software
DSC software
ABS software
M Track Mode software
Alpha N software
"CSL Software" for the ECU (Is all the above included in the "CSL Software" or is there more missing other than the above listed? Im confused on this one.)

I though all the above were the same between the CS and the CSL other than Alpha N. Correct me if Im wrong or if I am missing something.

Thanks for your help.

So a new ECU, Steering wheel and steering rack fitted and reprogrammed for 2.2k inc vat? Hmm, useful info.

Mine'll never be finished, nature of the beast.

Would look better with red wheels :whistle:

Agree to disagree then buddy, I don't think you could do all the work for that including labour and even if you could that is a couple of grand you'll never see back and more hassle.

My car is probably worth less than I've spent in mods too

I said that because i have a quote for that much Nathan. I'm doing this to my M3. :thumbs:

As for your car - i'd love to see the finish product... any pics buddy?

[Bounce]

Emissions in UK is just probe into exhaust (or the exhaust of another car altogether if your MOT station is so inclined).

:hahaha::hahaha:
