Piet Posted April 11, 2015 Report Share Posted April 11, 2015 Ive just been going through the bin and may have come across a discrepancy. In the bin Ive been using I have 4 values showing under not defined 0964 is FB 0A03 is EF 10964 is FB 10A03 is EF These values are correct. (they have to do with the COP) Quote Link to comment Share on other sites More sharing options...
Piet Posted April 11, 2015 Report Share Posted April 11, 2015 To see when it happens you would have to continously log memory addresses containing fault codes to see when they appear. Does anybody knows how and where the DTC codes are stored, at which memory addresses? Quote Link to comment Share on other sites More sharing options...
rkam Posted April 11, 2015 Report Share Posted April 11, 2015 I haven't spent much time looking for fault codes yet, but I'm curious about the bytes XERFLG1 and similar. Most of the predefined 20-byte dynamic records for logging contain a bunch of these. Dumped memory F800-FFFF to have a look now. (99.9% of the time spent on Microsoft Visual C++) The freeze frame data in my software version was stored here: FE1D: 30 52 00 1A 23 50 01 57 FF 00 00 00 00 00 00 00 00 00 00 00 FE32: 20 52 00 1A 23 50 01 A0 00 64 00 28 64 A5 00 04 10 00 00 00 Maybe useful memory addresses: XFRFR freeze frame for isocarb 9141-2 XFSPEND Fehlerendepointer Quote Link to comment Share on other sites More sharing options...
Avinitlarge Posted April 11, 2015 Report Share Posted April 11, 2015 Does anybody knows how and where the DTC codes are stored, at which memory addresses? Thats odd, they are different in a fresh COP bin compared to the bin I am using Quote Link to comment Share on other sites More sharing options...
Piet Posted April 12, 2015 Report Share Posted April 12, 2015 (edited) Thats odd, they are different in a fresh COP bin compared to the bin I am using Wrong quote I suppose? You probably ment this one? These values are correct. (they have to do with the COP) I have the exact same values on those addresses, no problems or DTC codes. There were two versions of the COP mod.

Turboforslund Posted April 12, 2015 Report Share Posted April 12, 2015 (edited) Hi, I've made a machined MAF mounting for Bosch HFM 5 (ME7 cars?) a while ago that I do not use anymore. If someone with ME7 MAF conversion thoughts wants a steel version of it I can send it for the postal costs. Plug included. Let me know if you're interested. // Turboforslund Edited April 12, 2015 by Turboforslund Quote Link to comment Share on other sites More sharing options...
Midnight Caller Posted April 14, 2015 Report Share Posted April 14, 2015 (edited) Hello guys, Regarding the in car ECU flashing. Do you think it could be done this way ? I'm thinking we would get rid of the relay and three pole switch, making life a bit easier. Could we connect the battery through a switch directly to pin #A22 on ECU (fan FULL speed), or are we risking to burn something in the ECU (the output driver for the fan relay) ? It's the red line in the picture : If when entering boot mode, the #A22 pin is driven internally to zero volts, applying battery voltage to it would lead to current entering the ECU. That would be OK that pin has high impedance, but you guys know better. If the pull-up / pull-down resistor is in the fan relay, I don't think it would be a problem. What do you think ?

Avinitlarge Posted April 14, 2015 Report Share Posted April 14, 2015 Why not just disable the fan, A22 on a switch maybe? Quote Link to comment Share on other sites More sharing options...
Turboforslund Posted April 14, 2015 Report Share Posted April 14, 2015 (edited) Hi! Most likely the ECU won't like the 15V input on the ground output. It might work, I wouldn't test it unless I have an unlimited storage of ECU:s. The simplest way would be to use a 6-pin switch that can "cut" the A22 cable when switching to boot-mode. Do you get my idea? It will require a lot more cables between the dashboard and the ECU socket but it will work! Why don't you just put a relay in, is it tight spacewise or other reasons? // Turboforslund Edited April 14, 2015 by Turboforslund Quote Link to comment Share on other sites More sharing options...
Midnight Caller Posted April 14, 2015 Report Share Posted April 14, 2015 (edited) Talked to a good friend of mine and we've come up with another schematic. I want to use only one switch, and keep things tidy (I'll disconnect A22 pin inside ECU and re-route-it through a 5 pin relay) like this. I wouldn't want to have a plane dashboard of switches just to be able to flash ) When switch is off, relay is closed between 30 and 87a, and the fan is working as normal. When I want to flash, I flick the switch, relay switches output between 30 and 87, and fan is disconnected. I'll be installing the switch on the ECU case, so on each flash I will pop up the hood, but anyway I won't be flashing when driving so I guess it's not a problem. @Turboforslund: We posted in the same time Edited April 14, 2015 by Midnight Caller Quote Link to comment Share on other sites More sharing options...
Turboforslund Posted April 14, 2015 Report Share Posted April 14, 2015 Yes, this is how i described it at page 237(?) eccept that I supply the relay with the 15V cable... I have 1 switch in the compartment underneath the stereo. Works awesome! // Turboforslund 1 Quote Link to comment Share on other sites More sharing options...
PFloyd36069 Posted April 14, 2015 Report Share Posted April 14, 2015 From my experience if you turn the key on then flip the boot mode switch, the fans do not run. I have flashed like that without issue but its probably not right! Quote Link to comment Share on other sites More sharing options...
