How to rework ICOM A2 with heatsink for Cooling chips

This is a great solution of ICOM A2 reworkwith a heatsink which is cooling both chips.

(GREAT THANKS to B1257)

Now here are some pictures about the heatsink I made.

Picture1 As you can see in my way the heatsink is made with two parts. The main center plate which will later touch the complete case for a better heat dissipation. And second the small CPU plate which is glued with a special Thermal Bound paste for FPGA chips on the center plate. You can see the compound type on the picture.

Picture2 Shows the Temp in C° after an idle running time of the head about 30 minutes, without any cooling.

Picture3 Original there are two pads for the cooling, but not one is touching the case, after a longer time the complete case will warm up in a way that the both chips are near out of max temp range, which is in a normal grade about 70°C. For our heatsink I will use a small pad for the MICREL chip to give me the right contact to my center plate. Second reason is that the pad gives me a little bit place for a realignment to center the main plate with both chips.

Picture4 You can see new srewls and bolts to compensate the new height. The screwls dimension of the innerside srewls is 2.5x12mm (countersunk bolt, this is important, because we cant fix the center place in the case if there is not enough place with normal screwls.)

Picture5 Be careful to center the plate exactly with vary the three plastic bolts, may you have to cut it a little bit. Check the space between the case and the center plate one or more times. Take care that both chips are touching the heatsink, because some cases can vary the height.

Picture6 Apply compound paste to the center plate, where the heatsink is later touching the case for the best heat dissipation.

Picture7 For the best way take care that the complete heatsink is touching the case. See the red arrow.

After the heatsink mod the temps are always inside the specs. I remember 5 hours idle running about 40.5C° room temp about 26°C.

I hope this helps you to mount the heatsink in a proper way.

So advice to all -

To avoid issues, please check the PCB design (with the cooling plate) before your buying. when buying from China, it seems diyobd2.fr is one of the safest way to make sure of things quality.

How to use ICOM A2 NCS Expert for BMW customer sight settings

Customer complaint:

I installed LED on my E60 Angle Lamp - and it comes out with this error：

Side/daytime lights on left faulty

Side/daytime lights on right faulty

anyway to get rid of it? I have ICOM A2 emulator & ISTA.

Suggestion from diyobd2 engineers and real users:

diyobd2 engineers:

You must code LMA module with NCSexpert and NCSDummy(easier)

Turn to "nicht_aktiv" option for kalt and warm monitoring, and CC Fehler for standlicht or TFL

real users:

Here goes the dummy guide to do custom Light settings - coding E60, E63, E90 LMA module using NCS Expert

You need BMW ICOM A2 emulator with working NCS Expert

Note 1:

changes are to be made in the LMA module using NCS Expert, with the E90 you need to make these changes in the FRM module

Note 2:

some of these changes are only possible for cars with a build date after 03/2007, but you can retrofit a new module to earlier cars if you really want the features

Note 3:

I have marked the setting I used with a star =*.

How to run ISTA-P with K+DCAN cable using ICOM A2

This is the instruction on how to run Rheingold ista / p with  K + Dcan USB cable  using  BMW ICOM A2  diagnostic tool.

 

1.Disable firewall.

2.Remove voltage constant.

3.Extract and copy the ICOM emulator xml files to:

*: \ Apps \ wsm \ apps \ agent \ data \

4. In VMware network editor, ensure "VMnet0" is set to "bridged" and your LAN network adaptor is selected in the drop down menu.

5. In VMware network editor, add a new network called "VMnet3" and set it up as shown in the picture below:

Note: Click "apply" and "ok" and close down VMware.

6. Open VMware again and start emulator using the k + dcan snapshot. Once it has loaded up, go to the vm settings and change network adaptor 1 to "VMnet3 (host only)". Click "ok" then wait 30 seconds for network to re-initialise.

note: you can now create new snapshot if you want.

7. Connect  K + Dcan cable  to emulator and car and run "Ifhsrv32" using icon on desktop emulator.

note: ensure k + dcan cable usb icon is active in the vm.

8. Start ISTAP native, start a session and choose "ICOM emulator" in connection manager screen.

note: if everything is ok, the led on your cable should start to flash after a minute or so. If not, recheck emulator settings (ie com9, latency timer set to 1 etc.).
