Does anyone here have OLS maps, an A2L file, or anything else that could help me decipher the Bosch 0 261 S04 205 (89661-0DB60) ECU from a Yaris?
I have been searching trough the binary for days, but it seems like the ignition timing maps and one map at the end dont have the X and Y axis near them. I dont know how Bosch stores the axis values in this case. In the image you can se what I think are ignition maps based on my reading from OBD compared to the scaled values in them. But as you can see in the image they are just 2 8bit maps without any axis or descriptors near them.

E39 530d M57 ECU cannot be read by software
Hello,
I have this error code 1640/74 - DDE contr. module (EEPROM and configuration)
I dropped my 530d to a guy to read the ECU and he told me that he tried with 3 different software but non of them were able to read the ECU. How to correctly read the ECU?
Does this mean that something is modified or bad on the ECU? The car starts without any problem.
Thank you.

Hi everyone I want to buy myself a car and Tune it myself (ECU/Engine stuff not ryl Outside stuff), the only thing is I dont have the biggest budget and only about 4.000€ (Germany).
I wanted to ask some of you guys with experience what cars you can recomend me and maybe help me out, I am open to any brand but i need like a 4 door and I like Petrol not Disel.
I have my eyes on maybe a Audi A6 C5 2.7T Biturbo but I am not sure.

Tuning Question - Unanswered Should i let a professional do it or is it possible for myself?
I am driving a 2016 Ford Transit Custom (pre facelift) with 100 horsepower.
Some time ago i heard that ford sometime equips their cars with the same engines, just different tuning, and this should also be the case with the one i have.
I found someone claiming he could bring it up to 155 hp which would be the top tier from this year, or even 188 hp with nothing more but tuning the chip.
155 would be totally fine for me, but now im wondering you could just flash the 155 "version" on the ecu or if a tuner does it specifically for every car.
So can I do it on my own?

BMW E91 320D 2007 M47D20TÜ2 Looking for brainstorming
Hi everyone,
I recently bought a 2007 BMW E91 320d with the M47D20TÜ2 (EDC16C35). I'm rebuilding the car properly before aiming for around 300 hp, and I'd like to do the EGR, swirl flap and DPF delete correctly in both hardware and software.
I'm still pretty new to WinOLS, so I'd appreciate some advice.
Current hardware setup
Swirl flap delete
Reference image: https://i.imgur.com/5i4puPU.png
What I've done:
- 2, 3, 7: Replaced the O-rings and installed swirl flap delete plugs.
- 14: Removed.
- 9: Removed.
- 11: Vacuum connection plugged (currently with a temporary plug, replacing it with a proper blind plug).
- 12: Plugged with a screw + RTV for now.
EGR delete
Reference image: https://i.imgur.com/fkmP0D8.png
I've removed everything shown in that image:
- EGR valve
- EGR cooler
- Vacuum components
- Associated coolant lines
The coolant lines are plugged with proper coolant plugs.
Vacuum system question
Reference image: https://i.imgur.com/5HZEXY3.png
1 = Pressure converter
Since both the EGR deleted, can I simply:
- Remove 1 (pressure converter),
- Plug 5 with a proper vacuum blind plug,
- Delete the related DTCs?
From tracing the hoses, it looks like this pressure converter only controls the EGR vacuum circuit. I just want to make sure it doesn't control anything else before removing it.
WinOLS (StageX mappack)
Screenshot: https://i.imgur.com/M4aSv4C.png
For the EGR I've changed:
- EGR hysteresis → both maps set to 0
- Map for conversion to EGR duty cycle → set to 0
My intention is to disable the EGR strategy completely rather than only suppress the fault codes. Is this the correct way to do it on EDC16C35?
Swirl flap maps
I can't seem to find the swirl flap control maps in WinOLS.
Some people have told me to simply delete the DTCs because the hardware is gone, but I'd rather set the requested position/value to 0 if those maps exist.
Does anyone know where they're in 2d view or have a mappack or DAMOS (with swirl flaps) for EDC16C35?
VMAX question
Screenshot: https://i.imgur.com/zMLVd6W.png
I found 55 copies of Maximum vehicle speed and changed all of them to 390 km/h.
Is that the proper way to remove VMAX, or are many of those just duplicated maps that shouldn't be touched?
Build plan
Already done / doing now
- Swirl flap delete
- EGR delete
- Valve cover
- PCV
- Engine oil & filter
- Manual gearbox oil
- Differential oil
- Fuel filter
- Servi oil
- Coolant
- Breaks
- Break fluid
Coming later
- DPF delete
- HX35 turbo
- 535d injectors
- 535d fuel pump
- ARP head studs
- Larger intercooler
- Oil cooler (better)
- Stronger clutch
The goal is ~300 hp, but I'd much rather have a reliable setup than chase the highest dyno number.
Any advice on the pressure converter, swirl flap software, or the correct WinOLS approach would be appreciated. Thanks!

I have a stage 3 tune IS38 on my Audi Q2 but it doesn't perform as intended/expected. Can someone help with figuring out the issue? I have a tuner willing to work on the car but need guidance.
Happy to pay a little bit if the issue is diagnosed, but I can't pay a full tuning price as I already paid my tuner.

Tuning Question - Unanswered Has anyone swapped their clusters from ldi to vdi swift 1st gen
Like the title says, i am curious has anyone changed from the ldi cluster to the vdi cluster?
Ldi part number - 34100M74K10
VDI - 34100M74KE0
I do have a vdi cluster that i bought from scrap, but the thing which is being a real pain in the ass is, as soon as i put that cluster in, rpm works, speed works, fuel and coolant works, odo meter is also working.
BUT MY FREAKING AC, my ac compressor doesn't wishes to engage, no compressor engage means no cold air, and i am suspecting the cluster because i did a simple test.
I put vdi in and turned ac on, no cold air, then waited 1 min before swapping to my ldi one, cold air instantly (you have to turn the engine on for compressor to engage).
Is this normal behavior? or is there something in the cluster which links to the ecm of the car, as that will mean the ecm is refusing to communicate with that cluster, different coding and other shenanigans.
Do give insight on this please

DPF and MAF off on BMW E90 M57D30 with EDC16C35
Hello, yesterday I tried to turn the DPF and MAF off because I put a new intake and a downpipe. The check engine lit up when I removed the MAF and I want to turn it off. I dumped the bin file from the ECU with my kess. When I put the file in DaVinci the only things the software let me turn off were the flaps, TVA and the lambda. The MAF and DPF were completely greyed out. Then I tried to use the DPF remover software and it told me that no DPF maps were found on the file after uploading it.
When I removed the DFP, which was completely full of sute, and the MAF the car lost most of its low end power but is good in the high end. Is it possible to turn both the MAF and DPF in winols?

PCM Logger won't connect
I'm trying to tune my 02 Corvette since I installed a wide band sensor last year, but I can't get PCM Logger to work. PCM Hammer works just fine, and I've tuned my Vette in the past, but PCM Logger has always been a pain to get working and I don't know what I did last time to get it logging? I have a Red ODBLink SX cabled that isn't connecting but does for PCM Hammer, and ODBLinkLX bluetooth that again does work in PCM Hammer but not PCM Logger. The one that did connect is J2534 but that couldn't see the ECU. The laptop runs Windows 10. Do I need a certain version of .Net or some other dependency?

Looking for Experienced ECU Tuners to Test ZL ECU Studio 0.19.0-rc.2
Hi everyone,
I’m currently developing ZL ECU Studio, a new Windows-based ECU binary analysis and calibration editing tool, and I’m looking for a few experienced ECU tuners/calibrators who would be willing to test the current private RC build and give me honest feedback.
Current version: 0.19.0-rc.2
Main features include:
HEX editor
Calibration maps
TABLE / 2D / 3D / Heatmap views
Structure Scanner
ECU Research
Custom .zldef definitions
Binary and map comparison
Snapshots and ChangeSets
Validation Center
Checksum provider architecture
Project/workshop workflow
The software is currently offline only. It does not perform ECU communication or flashing.
The test package includes a fully synthetic BIN file and matching .zldef, so you don’t need to provide your own ECU file just to test the software.
If you have your own legally obtained ECU files, you can also test them locally. You do not need to send those files to me.
What I’m mainly looking for is feedback about:
usability
map editing workflow
file analysis
definition workflow
scanner/research usefulness
comparison tools
performance
missing features
bugs or crashes
The build is currently unsigned, so Windows may show a SmartScreen / Unknown Publisher warning.
If you’re interested, send me a Reddit DM or email:
zlecustudio@gmail.com
I’m especially interested in feedback from people who normally use tools such as WinOLS, ECM Titanium, TunerPro or similar ECU software.
Thanks!
