  1. I get the same thing on mine, random MAF errors. Thought maybe the connector was dodgy but now you have the same issue I'm not sure. If you want to just stop the MIL coming on (error lamp disable in tunerpro) then you could add a new scalar pointing to 0xF39F (for the 608rev5b) and set it to 0. Otherwise, looking at the Damos there isn't a diagnostic disable for the MAF. However there is a min/max flow in kg/h for diagnosis and also a min/max RPM threshold for diagnosis. The mini flow is at 0xF239 and max flow is at 0xF23A. The min RPM threshold is at 0xF23B and max RPM threshold at 0xF23C.
  2. You should be able to add four new scalars in tunerpro (right click parameter list and click "insert new XDF parameter") and set the addresses to 0xF3AB, 0xF3AC, 0x1F3AB and 0x1F3AC and name them IAC open fault, IAC close fault, IAC open fault (upper bank), IAC close fault (upper bank) respectively. They should all be set to 1, change them to 0 to disable the MIL coming on.
  3. There is not a diagnostic disable in tunerpro for the idle control valve. I've had a look through the damos and unfortunately I can't see a diagnostic disable for the IAC. So it maybe possible to be do in the code somehow
  4. Don't worry, I made the same mistake years ago when I tried to hook up an AFR gauge to my narrowband. It's just part of the learning curve. I guess that back in the 90s wideband sensors were expensive and possibly not as reliable or available as a narrowband? or maybe the control technology was too expensive? Would need to research it for better clarification. The wideband sensor uses a different heater control method to the narrowband hence why a controller is needed (where if you hooked up the wideband direct to the ecu it wouldn't work properly and may even cause some damage).
  5. On our cars the O2 sensors are narrowband so can only read approx. 14 to 15 AFR (hence why your readings are going between 12 and 17 using your equation). You would need to fit a wideband sensor and controller to read a wider AFR range (to a separate gauge, you would need to modify the ecu binary to add it to the logging).
  6. What values are you trying to change from and to? It could be an issue with the step size as the injector opening voltages go in 0.0195V steps.
  7. Are you saving the binary as well (File>Save Bin)?
  8. You can add it manually in tunerpro, it's not listed in the XDF normally. Just add a new flag parameter and point it to 0xC8ED. Then you can change it to 1 or 0 for manual or auto. Fingers crossed it works
  9. Ok, had a quick look at both files. Your BMW MAF file looks ok apart from the alternative maps (used for map switching) are not the same as the normal maps. It could be these are being used for some reason. Plus, as you know, you've got it set to TCV Duty Cycle control only. The 80lbinjector file is a bit of a mess. It seems to be a 608 file (set for manual gearbox) but is missing the first 16 bytes so the whole binary is at an offset of -10hex and does not match a 607 file at all. It also appears to be the launch control version (maybe Rev6?). What I would do for both ECUs is start again with a base 608rev5b bin from HERE and copy all your modified values over. Set the hardware config (at 0xC8ED) to 0 for the auto car. That way you are ruling out the binary as an issue.
  10. Hmm. Upload your bin via dropbox and we'll have a look see if anything stands out
  11. Is it running the stock wastegate actuator? An old/weak (or even incorrectly adjusted) actuator can cause issues. Also check the "max TCV duty cycle" is set to 100% Have you checked the logging to see what the TCV duty cycle maxes out at when running? You'll need to upload via another hosting platform as attachments don't work on here work some reason so we can't download it. Maybe try dropbox?
  12. There used to be a signal description list for each pin but I can't find it any more. Fortunately I've got my own copy: https://www.dropbox.com/s/z0avaurxii29vth/Motronic44-1.jpg?dl=0
  13. Was the harness new or was it from another car? Sounds like you have it sorted Nice work dude! I guess comparing with other auto binaries may give us more info on that difference.
  14. Part numbers and flow rates need adding to the wikia then
  15. So the plot thickens. Like you say best to get flow tested to make sure you know the flow.
