Default Re: Comprehensive MSS50 DME information (Euro E36 M3 S50B32 321 PS)

Interesting, the software I believe is standard 3.18, if someone sends me a full read I'm happy to compare. I've two DMEs, the first is the one from the car and is the blue line above, the second is the other two runs but I've done a full write from my original on to it before making changes to the partial. Cam, ignition and fuel are all quite different from the factory map starting at around 3k rpm (you can see on the orange map I tried to tune out the flatness below 2.5k but failed miserably!).
I'm guessing we didn't kick up the coolant temp too much as we were often having to stop, reflash, start again then run for a min or so to bring the IAT down a bit before doing a run. I did perhaps 15-20 runs and on all runs was hitting ign targets.

Hi everybody,

I search a XDF file in order to understand the engine maps of my Euro MSS50 but I've only found the "M3-MSS50_1_5_WK9.xdf" file on TunerPro website. However, many maps are not well identified.

Someone would have a better XDF file ? It is not for business, it is only for me. I want to understand how it works.

Thank you in advance.

Guys

I have just converted my SMG S50B32 to a manual. How can I flash the DME with the code for a manual car?

Thanks
Hasan

SMG cars come with the MSS50.1 while the manual cars come with the MSS50, and I don't think it's possible to convert one to the other without reflashing the eeproms directly.

You could try flashing the Z3M software with WinKFP (I think it would be ZB# 1406560). Z3Ms were all manual and came with MSS50.1s

Hasan, you can disable that smg can logic via calibration reflash and use your mss50.1 software.

This is great news. Thanks

Now how do I go about doing it. Please note that I am not very good with tech or computers so I might ask stupid questions.

Really appreciate your help.

Ok this is maybe a bit off topic but I suspect it could be ecu related anyway.

I have a hesitation when blipping the throttle from idle on my 96 euro M3 3.2. Also it does this when changing gears fast from medium revs when the clutch is released again. When doing this it also stinks of fuel and you can see from the exhaust that it's running rich. When driving normally or going WOT and using the whole rev range it runs perfectly fine.


As you can see it gets better on higher revs

When I bought the car it had a cheap carbon airbox with the box cut open at the opening with the stock MAF put there with some silicone as sealant I of course thought that this was the problem and put a stock intake manifold in place and sent my ecu to the UK for a different map (it was mapped with the airbox here in Sweden by a company that don't have the best reputation). But this didn't fix anything.

I really have replaced pretty much every sensor I can think of, TPS, camshaft position sensors, crankshaft position sensor, oxygen sensors, MAF, coolant temp sensor, IAT and so on. Every single hose under the intake manifold and throttle body hoses, throttle body o-rings to head, cleaned injectors and so on. Nothing has made any difference.

I only have replaced the Vanos solenoid seals, not the other seals but it passes the Vanos test in DIS and also the solenoids click when tested individually in DIS. No fault codes what so ever.

So the Vanos itself isn't overhauled in any way but would it really pass the test in DIS if the seals were that bad to give these symptoms? And do they really cause rich running? The idle is perfectly fine.

So I'm beginning to suspect that my DME is bad perhaps? I have bought the Siemens MSS5X flash tool from chipster.no so once I get it running I was planning to try with the original DME bin file. If someone could point to where I could download it I would greatly appreciate it? 1996 M3 3.2 manual gearbox.

Otherwise is it common for these DME's to fail in any way? I mean my car runs fine except the hesitation when getting fast throttle inputs. Feels map related but I'm not sure. I kind of begin to give up on this issue, I have replaced parts for almost two years now without fixing it


Many thanks from Sweden

Does it happen when its hot ? or cold or both?
Can you scan it and post the results here. Possible coil problems.

Have a look at your long term fuel trims in INPA are they way off?

Log the data with testo especially the temps.. need to start to try and draw some correlations with the data and the fault.

Sounds like a short misfire on snap throttle.
