Never actually said that, but thanks for admitting. I'm also pretty sure there is a stupidity forum somewhere that suits you

Propain also has the "TTM Box Top Mod" where Bruce grinded out the flat funnel portion to replicate the flow of a "ROW" box top.

Vadim did a dyno a few years back that showed a slight increase from removing the charcoals and that is why we do it. As for your butt feeling it.....doubt it.

I just got my ecu back from Kleemann so I figured I'd change out the K&N's for AFE's and took out the charcoal. Now I've got a check engine light after about hour or two of driving. Got in it a couple times. Light came on coming back home. Does the ecu just need to get used to the new set up or do I have a problem?

Make sure your box tops are fastened down properly and your filters fitted correctly. The big thing to check is for air leaks downstream from the MAFs so make sure that the rubber Y fittings are properly fitted to the box tops (no buckles or folds) and clamped snugly with no air leaks/gaps.

i got my 11' e63 dyno'd today...before and after including the CD and the major difference was a pretty big dip within the 4000-4500 rpm range...has anyone else experienced that?

bhamg

Not giving you a hard time but just curious...is this number the result of an actual flow test or is it just guesswork?

I have tried removing my Carbon filters three times. Every time after a few hours of driving I get a CEL. I now run K&Ns with the carbon. I think some cars/ years are more prone to have the CEL when you remove them.

i dont think you can feel the difference

Yes you have a problem without charcoals. Well in my experience without the charcoals the damn CEL kept coming on even when driven mildly. I tried this many times without them. The damn ECU NEVER adapted. So I put them back on. The light stayed away.

Jons95c36amg

I think its the P30 c63. Since we both have them.

Maybe just '09s?

Hi Guys,

There isn't a year cut off where some cars get CEL for charcoal delete and some don't, but there is a variation in different software versions that make some cars prone to triggering a CEL while others can make many intake changes and never see a CEL. It seems Mercedes purposefully lowered a parameter that will trigger a CEL if charcoals are removed to desuade intake modifications.

Our tune adresses this problem for those of you experiencing this. Obviously with a supercharger strapped to a car we ran into this problem early in our development stages so it was easy to apply the fix to NA cars with charcoals removed as well.

This is just one of the many proprietary things we've discovered on the ME9.7 ECU to enhance customer satisfaction.

Good info. Seeing as you've done a lot of testing on this issue, can you lay to rest whether or not charcoal removal adds hp or torque?

Weistec

The result from our testing is in line with what others have claimed. We've seen a 3-8 wheel hp increase, the larger numbers coming from cars with other modifications and the lower numbers coming from standard vehicles.

No CEL with charcoal delete here.

Thanks! What do you guys recommend for an air filter?

Jons95c36amg

I hate you.

propain

Deleted the charcoals at 500 miles. 14,000 later no CEL.


You got the CEL back after taking them out the last time?

Jons95c36amg

Yes. I drove it for couple days. Kept coming on and turned them off with scanner. I wanted to punch the dashboard. BTW I made mends with Bruce. Saw him at Mexico. I need a updated tune.

propain

That sucks. Maybe re-flash your tune and try again. I would let the light stay on a few more days. It might go away on its own as the ECU adapts.

Good to hear you fixed your relationship with Bruce. He is really not a hard guy to get along with.

I was thinking on heading down this Sunday. Ill look for you. We need better MB turn out.

I have an 09 P30 and I just removed my carbon filters this weekend. Within 2 days (about 100 miles and 3 or 4 starts) of driving I got a CEL.

Not too concerned because I am getting a tune this weekend which will get rid of the CEL!

I bought a set of CF air boxes for my car, I had them installed for about 2 weeks before I noticed that the stock air boxes I had was actually ROW models. I guess they came with the brabus kit. Which in interesting as its not mentioned in the kit. Luckily i sold it for exactly what I payed for them, thank g** as i (and my gtech ) could not feel a difference between them and ROW ones. After following up with someone from brabus they mentioned that the ROW's should be good for (2hp / almost a rounding error on a standard dyno) but +-10hp at 100mph on the road

cptdaz

I notified my tuner of the change before getting ecu flashed. Maybe you just need to reinstall another tune?

propain

I was thinking about this Jon. When you remove your charcoals are you still running OEM filters? Maybe try upgrading to the K&N's and see if the better flow helps.
