Seeking CSL knowledge.

[cntrvrsy]

What's the usual emissions test procedure for the CSL owners? As it's looking now, the Alpha-N conversion required to run a CSL box will not pass OBDII emissions testing in the states. Some states and even some counties within a state have different mandates but if you're car is required to be tested through the OBD port, it won't pass. I hope a way around that is found because that's the only real thing holding me back from converting to the CSL airbox .

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

All in all Nathan - I've calculated that CSL steering rack incl. labour to fit, M track mode (which you could well do yourself) steering wheel in alcantara, M3 CS - DSC and ABS reflash (due to quicker steering ratio) + MSS54HP ECU, all comes down to £2200 max.

2003 E46 M3 can be found for around £11'000.00 and if costs is an issue then surely the extra monies could be spent to buy second hand APs, CSL bootlid, rear difuser and maybe a slightly damaged front bumper.

Turning standard M3 into a CSL is quite expensive and costs add up bloody quick!!

Most of the things i bought for my M3 are second hand (in a vey good condition... but the CSL bumper!! :hahaha: ) and my modifications now costs more than whole of the car is worth..... which reminds me, i still haven't done the cracking rear subframe nor the recall on SMG relay module.... :banghead:

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?

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.

cash job and the steering wheel done in alcantara. :thumbs:

looking good there! :thumbs:

Would look better with red wheels :whistle:

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.

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.

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.

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?

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.

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