Remote SD card
I've tried a couple of sd card extenders as my MS3X is buried behind the dashboard and not easy to get to. All come back with sd error when I plug in the sd card to the extension . They work fine in my laptops and the sd card also works fine on it own in the Megasquirt. Has anyone got anything like this working.

Re: Remote SD card
It is unlikely to work reliably. The signals to the SDcard are not designed to be exposed to the harsh automotive environment.

Re: Remote SD card
i do this myself alot. you cannot insert the card with the ms on, it needs to be in when it is keyed on. the extension trips a physical switch in the socket and if the switch says it is in but there is no card it errors out and stays that way. it needs a new boot up to work

Re: Remote SD card
The datalogging works absolutely fine James when I have an sd card in the MS3X unit itself. I have no issues at all. I just wondered why it didn't work with sd extender leads like these.jsmcortina wrote:It is unlikely to work reliably.

Re: Remote SD card
I just couldn't get it to work whichever way I tried. It's not a big issue, I just wanted to be able to access the sd card without removing parts of my dashboard. My car isn't a race car so all the trim is fitted.ashford wrote:i do this myself alot. you cannot insert the card with the ms on, it needs to be in when it is keyed on. the extension trips a physical switch in the socket and if the switch says it is in but there is no card it errors out and stays that way. it needs a new boot up to work

Re: Remote SD card
That was my point. The SDcard signals (SPI) are ok inside the MS3 case, but outside the case in a cable, who knows. It wasn't designed to work like that and will be at risk of interference or damage to the card or ECU.
As I said before though, aren't you able to use the SDcard downloader?

Re: Remote SD card
Sorry, didn't see that last bit you asked.
Yes I can use sd card downloader. I know it's not supposed to be used like this, it was just something I decided to try as I had a spare extender. Like I said, it's no big issue I just like experimenting, if I didn't I'd never have put the MS3X in my £200 Nissan Micra haha.

One of the "eye-fi" wifi enabled SD cards might work...

Re: Remote SD card
Never thought of them. It's really not a problem tbh. My car isn't a race car. It's just a modding hobby one. Therefore the more things on show the better when ppl have a look round. I just wanted my Megasquirt stuff to be more apparent without having the whole unit on show. Thanks for the input though.

Re: Remote SD card
James is absolutely right... the signals going to the SD card don't "travel well".
But it can work sometimes. I've been doing it for a while, with an extender very much like the one linked above, although mine has a shorter cable (about 10") which may be important. I also have "SD comms speed" under the SD datalogging menu set to "Slower"... if I increase it, I have problems.
The SD downloader works for me but is impractical... I don't download files very often so when I do, it takes hours to download them all.
