And 3rd/4th, 5th/6th, and 7th/8th values are repeats. This appears to be true for all entries mentioned above.

I wonder if some of these are min/max values to set DTC. I also wonder if some of the stuff later on are memory addresses to jump to in code.

dschultz · **Posted:** Thu Sep 25, 2014 2:38 am

Could any of the entries be related DTCs to be checked in conjunction with the current entry?
The Subaru code has that but uses a different format for the relation between DTCs.

tkelly278 · **Posted:** Thu Sep 25, 2014 7:15 pm

Let take a look at two DTC's that should be similar, lambda bank 1 and lambda bank 2 75 and 76

Code:

db  75, 20, 48,  1, 48,  1, 48,  1, 60,252,229,232,137,241,240,233; 

db  76, 20, 80,  1, 80,  1, 80,  1, 60,252,229,232,145,241,241,233; 

1 - 48 would make sense, you wouldn't want your O2 sensor going below a value of 1 and above a value of 48 since the max output is less than 1V and it is a 0-5V input pin in the ECU. 255/5 = 51, and a NB is never > 1V.

Why is the second bank 1, 80 then?

77 and 78 are similar. If you think it will help, what I can do is re-enable the rear O2's and use my stimulator to increase the voltage being fed to them and see when they set off a DTC. If those are setting min/max then the first bank will throw a code before the second bank. If that is correct bank 1 should flag at a little over 1V (54/255 * 5 = 1.05V) and bank 2 should flag at ~1.7V (86/255 * 5 = 1.68V).

I made a bin with all the dtc's in the XML disabled and it got rid of the CEL. This is the first time I've seen the dashboard without the CEL, so kudos to d_munter and mrf582 for finding them and getting them into the xml.

I do have some DTC's though

P0170, P0173, P1188, P1189

I am still using my handheld scanner. Can someone help me find a way to match those codes with the codes we are using here?

These codes are saying that the fuel trims are not causing changes in the O2 sensor readings. Using Testo I am finding the fuel trims are all 0, additive and multiplicitive. Think I'll hook up the simulated NB to the front O2 inputs. It is stuck at high 11's low 12's for AFR and the front O2's are reading about .4v, so whatever is going on is confusing.

Also helpful to this would be to figure out when the transition from closed to open loop occurs and to disable closed loop. Maybe that should be in a different thread? I will try some more drastic tuning changes in the low load/rpm sections of the map, but I think something in the malfunctioning closed loop system is over riding those changes and forcing the 12ish AFRs

I used to get those exact codes when I was supercharged. From the hours of research I did, they were mainly related to vacuum leaks. Other causes were a faulty MAF and faulty o2 sensors.

I think these are telling the device how to look for these codes. They are probably going through routines to check for the flag.

I wonder what would happen if you set it up like this

Code:

MEM_EXT:25CC                 db   3,  0,  0,  0,  0,  0,  0,  0, 60,252,229,232,[b]147[/b],252,146,252; 1A0h

MEM_EXT:25CC                 db   2,  0,  0,  0,  0,  0,  0,  0, 60,252,229,232,151,252,150,252; 1B0h

You would know it worked by pulling the coil plug for cylinders 2 & 6 and seeing which one you get a misfire code on. It should be reversed.

mrf582 · **Posted:** Tue Oct 21, 2014 5:40 am

Agree with that logic. Maybe that portion of the code is a reference to the OBD2 comm section of the ROM which tells it whether to report a PXXX2 or PXXX6 through OBD2 diag. So if you swap that code as indicated, then reading using BMW tools might show the correct DTC but reading via OBD2 will show the DTCs swapped. Just a theory. And if that theory is correct, then that code should be looked at in hex instead of decimal as the hex probably points to a memory address in the code that processes that request.

tkelly278 · **Posted:** Wed Oct 22, 2014 3:53 am

I have blown the head gasket in my E36. I think it was on one of the last trips to get gasoline. It probably detonated from too much boost, lack of fuel, and ignition timing.

Turbocharging or supercharging without bigger injectors and control of the tune is not a good idea... yet.

At this point my primary concern will be figuring out how to read, modify, and turn off DTC systems. If this is figured out before I can rebuild an engine I might swap something else in.

I am getting an OBDI E36. No boost, but it is a 2 door, has a working automatic transmission and a M3 exhaust.

The engine will run enough to try the code swap tomorrow. If that works I will try to replace two of the codes, then all of them.

I will be working on something else for the rest of tonight. This has been a frustrating experience.

tkelly278: sorry to hear about your blown headgasket. Nobody wants that

For me it would be easier if someone with MS41 generated DTC on purpose and then took a trace file with testo to see raw bytes and how ediabas resolves errors. Good idea or not ?

I don't know who that guy is but I would LOVE to have him join our forum! I did send him a quick email.

We may also be able to go through the MS411DS1.prg file and find the DTCs like this guy did for MS80.

I'm not really sure what to make of all that data on the side.

I don't want to run this engine any more than is necessary. Instead of spark coils I will be going for the TPS and attempt to make a TPS error show up as something else.

Thanks, appreciate it. What we are seeing here is EDIABAS "translating" bytes what ecu has sent into resultnames and values. How these are mapped into OBD2 codes, I don't know.

You don't have to run the engine to read the codes I believe. Reason I asked to run a trace is that from the tracefile you can see what bytes ecu has sent and how EDIABAS has resolved them into resultnames/values.
