MAP sensor problem?

[S54B32]

I was under the impression that the paffy/terra software had stock csl fuel maps as well?

That’s the right, Stock CSL Fuel Maps for stock CSL cams, but no fuelmaps for standard m3 cams.

Yes, it has stock csl fuel maps

Only the Offset ist changed here for OEM cam‘s, that you can pass the Vanos routine. The Fuel maps are still CSL spec. So your car will run very rich under Full load and a bit Lean under part/light throttle. And of course have less power that before.

I don't know if this is paffy/terra software, but this guy has some csl binaries with the stock cam profiles. I bdm'd one of these to my dme and I'm just waiting on some backordered parts to install my csl box and try it out.

Did you convert your non HP DME to an HP? 03 here, although I don't have MK20 ABS (I have MK60) so I need to check if I have an HP DME or not.

I have an early '03 (March) with MK60 but non-HP. Not sure when they switched over.

is the paffy/terra csl software WITH the non CSL cam profile somewhere to be downloaded?

Here’s the simple solution to solve the confusion for those having an issue on a TTFS tune: Walk away from the money you spent and get it fixed by someone else. In my case, It was Paul Claude. My conversion went from running like shite, and there is nothing more we can do according to TTFS, to running perfectly after Paul’s base tune and then a few revisions.

I’m not trying to start a bash TTFS thread; this was my experience. I realize others have had no issues with them, but I was ready to give up on mine.

I had a similar experience. My old S50B32 swapped car never ran perfect, then when I installed cams, it ran horrible. Nobody in the US wanted to touch the euro DME, until I found Kassel, who said "sure no problem." I sent my DME to him and he sent one back that ran 1000% better. The car all of a sudden was nice to drive. I then went and had the car dyno tuned at his shop and he found an additional 46rwhp. I would have love to seen the power difference between the previous tune and his dyno tune as my butt dyno felt a huge difference between the tune that came on the car and Kassels initially tune. After his dyno tune the car was a rocket!

TTFS custom tuned mine on their dyno too. It ran like crap, idled like crap, knocked at certain rpm/load, they even lied about the dyno graph they gave me by manipulating the roller inertia values on the spot then denied they would ever do that.....

Anyways... Since then I've learned how to tune a bit myself, the paffy/terra CSL tune with non-CSL cam vanos profile is a great start and light years better than anything TTFS ever did and from there you can tweak and tune.

Yes I did. I documented it here: https://nam3forum.com/forums/forum/s...=2582#post2582

I would just reuse your DME, flashing back to stock software is as easy as flashing to CSL software. Kassel has a MAP kit (which is what I have on my car), but there are a couple other options, including sourcing the CSL rail or tapping into the brake booster line with an adapter for the sensor. I'm currently running the stock CSL tune and the car runs fine. Waiting to wrap up a couple other projects before putting it on the dyno.

I personally don't have a flap, but if you want to run one the only thing you have to do is solder a component onto your DME and wire in the flap. Pads are already there for it and it will work out of the box with the CSL tune.

Very helpful, thank you for the explanation Heinz. Does it make more sense using your own HP Dme, or finding a spare?
MAP Sensors; is Kassel the only one offering? You haven't listed your tuner (not crucial) - but will go on a Wim and say PC?

Side note: 1 thing that bugs me - is not having a functional FLAP ( IE; Heatsoak, etc) Just doesn't feel complete w/o this to me.
But, maybe thats nitpicking, what do you think? OR is the most proven (DYNO) setup on how to run the Airbox.

In my eyes, a carbon airbox conversion is basically as straight forward as any other mod. Especially now that people have made modified versions of the CSL software that can be flashed through the OBD II port without even having to remove the DME from the car (caveat here is that you need an HP DME).

The process is basically this:

• Install airbox.
• Install and wire MAP and IAT sensors.
• Flash modified CSL software using MSSFlasher (or flash regular CSL software via BDM if you want to convert the boot sector too).
• Modify two values in your tune to adjust VANOS offsets so that the tune works well with your cams.
• Go to the dyno and get everything dialed in for your specific setup by your tuner of choice.

I think the confusion stems from the fact that there are a couple ways to go about the conversion (alpha-n or MAP), but if you stick to the way that BMW did it (so that your car will run with the stock CSL software), it really is no big deal at all.

It's frustrating to me, to still see how much *confusion* and mis-information circulates about properly getting the Carbon Air-Boxes to function.
If not for this - I surely would have jumped in on the fun. Undoubtably one of the sought after mods for the platform. But yet, nobody has seemed to get this
running foolproof/ and plug and play to this day?

My comment wasn’t directed at anyone specific. I simply meant the ENTIRE Carbon airbox theme. All gets mucked up, and convoluted with how to get it to work properly. At least that’s been my perception, after speaking with many owners & reading a bulk of the threads on m3F. I do agree with you on the later, that I’ve always read positives with regards to PC. And hasn’t claimed any engines from what I know lol.
