hi i had the same issues. i tried many different cards and they did not work so end up buying a new edl to take out the sd card . i now have a spare edl. i still dont know why is so hard to get the correct sd card @Jadzwin_ECUMASTER can you please advise on this error ?
Please contact your local ecumaster dealer. We have good cost effective cards that are verified and works perfect. The problem is that modern sd cards are not compatible with sierial protocol and behaves oddly.
Iāve made a small tutorial how to set up idle control

Could you make some pictures of the cards that dont work for you ? We will try to buy them and check why dont work.
All of these donāt work.
SanDiskās SDHC 8G also didnāt work, but I donāt have it here so I couldnāt get a photo of the model number.
I understand that SD memory is an industrial product and that some will have defects, but none of the ones I bought work properly so I decided to post this.
If you know anything about it, please let me know. Thank you in advance.
Most SD cards are formatted in FAT32, and this is also the case for these.
However, I have tried formatting them many times. I have also tried changing the allocation size and formatting them. Is there anything else I can try?
As a side note, it was possible to update the firmware even with an unusable SD card.
(Initially, I updated from 1.18 to 1.19 using the SD card on the right of the photo. It worked fine, and the backup file was also saved.)
After the update was complete, the light flashed red and it no longer worked as a logger.
Currently, I only use the microSD that came with the EDL1.
Well as you wrote i have done it correctly, used small pids as you say to compensate for stuff, but even if idle airflow is tuned perfectly when rpm drops it doesnāt follow idle target and 50% off cases engine stalls, thatās why i started to use high pids and now it following target line but with oscillations.
i even done idle ignition map on dyno to get middle torque numbers.
Maybe because of big injectors or cr

When the engine stalls during rpm drops then pkease try to work witgt he ranp down offset
I thought i was a little crazy and missing something but i dont think i am , having read through the idle setup post after i had setup my idle control i thought i was missing something and maybe i still am !
But on a 1jz EMU black with the stock unipolar iacv i cant seem to get it to control the IACV when active state is there pre start to increase the DC of the idle valve.
I took some screen shots of the setup , overriding and changing to switch based however does activate the IACV im a little confused on what im missing !
Any help would be appricated ! , running 3.050
Even that is sometimes not enough
- when you have an engine with big cams, stupid light flywheel and long intake way from injector to valve - the rpms drop so fast that you either have to disable overrun stragety completely, or set it up so high in rpm that there is basically no overrun fuel cut during normal driving (bad efficiency)
The engine stalls when the revs drop because there is not enough time for fuel film and good mixture for regular combustion to develop. A good function would be a overrun fuel cut override when rpm drop is very fast (unit is rpm/s) which engages fuel earlier when the rpms drop very fast. That way you have regular overrun fuel cut rpm during driving(close to idle ramp down offset max rpm) and an increased rpm according to a 3d table (rpm/s vs coolant temp vs fuel rengegagement rpm) when you rev the engine freely .
Iāve tested firmware 1.19 with several SD cards I have at home.
Here are cards that are working without issue.
However I have one card (Noname) that behaves as you described (you can upgrade firmware but doesnt work for logging). It seems to be very very strange and I investigate this.

Hi,
Faced an issue I assume is an bug?
Using 3.050 FW.
Using PWM relay controlling FAN via AUX 2 output on ECU.
When using Outputs - Coolant fan strategy, it keeps pulsing even if put min DC 20% or 0%. Even if its inactive it keeps pulsing and fan is turning.
If using PWM #1 Parameters, function works as it should and output is off when no RPM.
Best Regards, Rasmus Mƶller
It pusles because some fan controller enter failsafe mode when there is no PWM signal.
They start to work with maximum power.
You can set min DC very low as the fan will not move. Or if it is an issue I can add an option that allows to turn off PWM when fan is not active
I fixed the issue with the one SD card I had. It was a problem with the sector write (thatās the reason it works for firmware updates, as the read works okay).
Iām not sure if it helps you, as some SD cards donāt follow the SPI specification properly.
I also added some EDL diagnostics for 3.051
https://www.ecumaster.com/files/EMU_BLACK_V3/edl_firmware_1_20.zip
We will also buy some of the popular available cards, make tests and publish a list of compatible cards.
RELEASE NOTES
Version 1.20
- improved SD card compatibility
- updated communication protocol between EDL and EMU BLACK (requires EMU BLACK firmware version 3.051 or higher)
- added diagnostics via EMU BLACK log channels (EDL group) (requires EMU BLACK firmware version 3.051 or higher)
- fixed bug where the green status LED incorrectly indicated active recording after SD card removal

Hi,
Thank you for reply.
I think you missunderstood me.
So in Coolant fan strategy, when selecting PWM control it never shuts it off even if the tab āTurn off when no RPMā is ticked. So even if min DC is 0, it still buzzing in electric fan motor.
How ever as you can see on these last 2 pictures I posted, when turning Coolant Fan strategy off and setting up the same in PWM #1 table, ticking the box āDisable when no RPMā it shuts off output and AUX 2 is not active.
I will check it tommorow. But for sure the coolant fan strategy will always send pwm signal. In this case it will be minimal dc (probably around 5%).
The PWM output will not send any signal when is turned off
when using coolant fan control with my Audi A3 8P, I have to use āinvert outputā or the fan wants to run all the time. The ecu doesnāt have control of the fan without the invert output box checked.
not sure if thats related in this setup as I donāt know what your setup/build is. but worth a try maybe.
It depends on output type. For Hbridge output there must be output inverted as the hbridge is in low state when off and high state when off. Aux and inejctors are in low state when on
