Dumb Question Thread - No Flaming Allowed

Are we still doing the painted reflectors in the front bumper? Some days, the amber are an eye sore, but I also think to keep it original. I have to get the clear film removed from my bumper and if the paint flakes, I'll just go get a euro bumper I guess. But if it doesn't, painted reflector inserts, or no?

I liked the painted reflectors the P.O put on my original bumper, since have a Euro bumper, but only because the original got a crack in it. The stock bumper with painted reflectors is a good compromise before shelling out for a Euro.

Should I be concerned about just firing it up after the engine sitting for close to 2 years....I realize the fuel could be an issue, but the tank is pretty much empty, so my plan was to just crank it with the ignition and no fuel to prime the oil pump and then start it up, but I've never let an engine sit this long.

Yes, I've used the ecuworxs tool, and it does allow for that, on e9x as well. Just curious, trying to learn more about coding, thanks.

Yeah absolutely - it's great to get into it and understand what's going on behind the scenes. If you have other questions or would find a “how to get started” guide or something useful I'd be happy to help :-)

This thread (https://nam3forum.com/forums/forum/s...me-information) is a good place to start. Essentially once you've got the the partial read off you can check a known memory location with a hex editor to get the version.

To quote that post: "Version Information is taken from the .0DA binary itself, 0x7FB8 for the MSS54, and 0xBFB8 for the MSS54HP, and is 56 bytes long".

If you want an easier way to do it I *think* that the ECUWorx tool lets you check the throttle curves.

Yes, that's what I'm feeling. Imola Red has the stock CSL tune + airbox and feels less responsive under 4K RPMs and if I “blip” the pedal I don't get that snappy, torque-y response with the sport button on like I do with the stock Jet Black.

I'm plugging in both cars tonight when I have a moment to check the curves! Thank you for the steps!

I think that's probably the result of running the stock CSL tune. With standard cams and exhaust valves the stock CSL tune isn't great for drivability and suffers from what you're describing. I noticed a big difference between stock CSL and where I ended up with my tune after a few revisions (I have built my own tune along similar lines to what Bryson has done).

curves are the same between my stock euro tune (1901) and stock CSL tune (0401).

1901


0401


I'd say it would be worth checking the tune on your Jet Black to see if the curve has been modified at all. I presume too that you're saying it's the sport map specifically that feels flat on the Imola? e.g. if you're running a stock CSL tune on a normal S54 with just a CSL airbox the throttle is going to feel less responsive and torque-y either way down low - could that be some of it?

To check the tune on your jet black you'd need to read off a partial (tune) and then open it in TunerPro using the correct XDF for whatever version of the software is on your DME. The curve you're looking for is KL_PWG_SOLL_SPORT as in my screenshot above.

How would you know which one?

Just the CSL software from Kassel Performance. I have no idea if the sport pedal curve was modified… whatever the standard CSL software would have I imagine!

Stupid question: how do I check the curves?

Sweet - I'll check when I get home from work if there's any difference between the two stock tunes - will post a quick how to as well (can't remember the names of the curves offhand)

What tune do you have? Was the sport pedal curve modified at the same time do you know?

I'd check whether the curves are the same between the two cars (presuming you haven't already)

Okay -

I have two M3s (currently) and they're both SMG. 6MT LSB on the way tomorrow.

Jet Black M3 sport mode button on my standard, unadulterated M3 is “jumpy” and feels fine. Throttle response is great with it on. With sport mode off, the car just trudges along calmly.

Imola Red M3 went through an MSS54HP CSL DME swap as well as a Karbonius airbox. I don't remember whether I had any issues with sport mode before the swap, but sport mode now feels nothing like the Jet Black. Does the CSL DME have a less jumpy sport mode map? Could it feel weaker because of a bad throttle position sensor? Bad pedal sensor? Throttle bodies getting blocked by clamps?

Located in California - SMOG related questions. Dumb question and I did some googling but couldn't find anything related to Martyn's MSS5x software.
If I used it for example enable shift lights I understand that modifying even something as small as that will fail smog.

I also understand that when using the MSS5x binary modification tool you take a backup.
If I just loaded that backup, is it to my understanding that that would allow me to pass smog?

You will pass with the shift lights that were added using Martyns tool.

I’ve passed multiple times with edited stuff. I actually edit my stuff using that tool in order to pass smog.


No need to swap back to original unless you turned off the cold start procedure. (That will turn off the SAP and flag the smog system)
