I researched Multiecucsan a little bit. If I recall, a Bluetooth ODBII reader is unable to perform certain functions. Whereas the ODBII USB can perform all.

I sent them an email and never received a response. Kind of lame.

 

Not sure, I use a usb interface myself.... I know the gray cable is required to access modules via the hi-speed CAN, perhaps the bluetooth is not fast enough for this ?

 

That's the only thing I can think of, it's just too slow. What adapter are you using? I see that the OBDLink SX USB is recommended from a MES distributor site. It also isn't too bad @ $30 on Amazon. That'll put me at $120+ in different OBD adapters. ugh. The OBDLink MX bluetooth adapter works fantastic for Android Auto/OBD2AA, and Torque though, so it's not a total waste.

 

I'm using the cantiecar interface (V3) myself.... Had this for my previous Alfa's as well. It's a more expensive solution, but the advantage is you don't need any additional adapter cables as it's a multiplexed interface.
Not completely true though, small problem is the version V3 I have (older type) doesn't yet support hi-speed can on the multiplexer, so I still need the gray adapter for certain modules. This works though. The improved V4 of the cantiecar works fine without any adapter cables.

Ah, yes, I believe I remember reading about that. That's a bummer, that's not a cheap device.

Well, I have the adapter cables, and tomorrow I will have the OBDLink SX USB interface. Fingers crossed!

What do people use for an OBD2 reader? USB, WIFI, Bluetooth? I would hate to buy a USB OBD2 reader when someone else has a bluetooth OBD2 reader working in this fashion.

Cheers,

I bought this guy after my BAFX OBDII reader didn't work. Just make sure you set the interface to ELM 327 WiFi in the MES app and you're good to go. Gray adapter plus that ELM reader work great, got me out of my brake situation and I tried out Dyno mode for a little with it too but have to revisit that.

 

I use this, basically all you need for giulia with multiecuscan, works like a charm https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/282772601430

That's what I use also.

 

This is all great info and should be able to help out others.

 

I did some research into the OBD readers when I was installing paddle shifters and came to the same conclusion that others above have. The bluetooth ones are great for being unobtrusively plugged in all the time, working with iphone/android apps like Torque for data logging etc, but might not work for the proxi alignment procedure (which uses the blue and grey adapters) that I needed to add the paddles.

Also, you can use the windows version of MES forever (only have to pay again if you want an update after the 1st year), while as far as I could tell, for the iOS version of MES you have to pay the fee every year to keep using it.

 

What can you do with these?

 

You can view vehicle data (rpm, temp, a/f ratio, fule level %, etc.), reset service interval, enable dyno mode (all nannies off) temporarily, and a whole slew of other things.

 

Whelp! The OBDLink SX USB adapter doesn't work either. So the only other variable I have are the adapter cables I purchased. They specifically state they are compatible with Alfa / Fiat / Lancia and MultiECUScan. So I doubt that they are the issue. I'm getting terribly frustrated at this point. I've just discovered the support email at MES, so I sent one off.

Same error

 

Whelp! The OBDLink SX USB adapter still doesn't work. ............

on the MES website you can see how the adapter cable 6 (grey) needed f.i. for the ABS should be wired, also make sure it's not overly long.... :

As I understand you're using an SGW bypass, it could of course also be that the relevant CAN network is not bypassed correctly ? .....

 

I think I have the same set, as said I only use the gray, but that works fine in my case.....

 

If there is any chance that someone could test their gray #6 cable that would be most excellent. Hold the male and female ends in the same orientation as the picture shows (use a paper clip to get into the female connector). Check if female pin 6 really goes to male pin 12, or if it is female pin 3 going to male pin 12 (or even pin 13 as I don't think we can trust pin numbers here).

Thanks.

 

here's the official pin numbering for the OBD port btw

 

Usually it's sufficient to just have ignition on, but you can always try

 

That was my understanding.

 

A lot of stuff doesn't come up/work when the engine isn't running. For instance, the DNA dial, auto start-stop button, etc. So it's not inconceivable to me that some modules may not be (fully) online when the engine is off.

 

I'll try that out to see if having the engine running does the trick.

 

Nope, that made no difference. It still cannot connect to the ABS module even with the car running.

I'd really like someone to test their adapter cable, it's the only variable I can think of.

 

PS the fysical layout of the pin numbers of the adapter cable in the picture is as seen from the cable side
so yes, if you look at the pin side you need to flip ....

After further testing, I discovered that the blue #5 adapter cable does allow me to connect to the blind spot monitors... so now I have a pin reference.

I checked the pin-outs on the gray #6 adapter and it is correct. So it must be MES that is not working on my vehicle.

I do get INVALID ISO CODE errors when running a SCAN using just the OBD2 adapter without cables... so maybe I have some new module versions that MES isn't aware of.

So much fun!! ?

I'm told that MECUS throws that Invalid ISO Code with all NA Giulias and Stelvios. The lead developer told me, it causes zero loss of functionality, just a reporting datapoint.

The new codes are supposed to be rolled into subsequent versions... so far, the latest version still displays that error.

 

MES is under continuous development, so is the giulia/stelvio, so it's to be expected not all ISO error codes are recognised.... You can however usually reset the errors, despite the fact they're not recognised, if you wanted to do so
I'm assuming you have the original MES 4.4. from the official MES website ? ....

I would still sooner expect a problem with the bypass module, as it (MES) seems to work fine for myself and others....

 

The plot thickens! I received a response from Yanislav (developer of MES) and he believes it is the SGW bypass from EuroCompulsion. He says that the bypass from ZAutomotive is also known to have this issue and suspects the EC one is no different. They are both lacking the necessary connections.

Here is Yanislav's response.

Hi,
It is most probably a problem with the SGW bypass device. We haven’t checked/tested the device from EuroCompulsion , but the same problem is present on the US SGW device from ZAutomotive.

These devices need small modification to work correctly with Giulia/Stelvio. The modification is wire between pins A1 and A2, and also another wire between pins A8 and A9. The pins are indicated on attached photo.

Here is also the complete correct wiring diagram of SGW bypass device. The wiring in red is missing in US devices and it is causing connection problems with ABS, Airbag, Steering and adaptive headlights.

Regards,
Yanislav Karagyozov

I guess I know what I'm doing this evening!

Looks like you are the guinea pig on this forum for MES with the SGW bypass. Your struggles will be appreciated by those that follow, so thanks for documenting.

 

So if true, I was right

Hope this will solve it for you, but I am fairly sure it will ......

 

Ha, yeah, so you think that having all physical connections is necessary?

 

pffft, that's crazy talk.

Yep. The EuroCompulsion SGW bypass is a bit different, but the exact same pin layout and procedure.

I ran home during lunch, ripped out the SGW, opened it up, jumpered A1 --> A2, and A8 --> A9. Opened MES, connected the gray #6 adapter, the OBDLink SX USB device, and proceeded to connect to the ABS module successfully. I was able to enter into the rolling mode / dyno mode.

Here are some photos, just for the heck of it.

Jumper pins:

I am a lot more twitchy in my old age than I once was... HOW MUCH IS TOO MUCH CAFFEINE?!!

My main reason for all of this is to enable Dyno Mode. Once you connect to the ABS module in MultiECUScan where that setting resides, the car starts its disco mode of warnings and fun indicators. No worries, just do your thing, it all works out in the end.

 

@toby@eurocompulsion @Chris@Eurocompulsion I wanted you both to see this topic as this will affect your customers. The bypass that you are selling is only good for the ECM, it will not allow connections to all of the other modules like ABS (Continental).

 

Enjoy dynomode haha, been dring for weeks on dynomode only, car feels so alive its surprising

 

I would assume that my experience will be a bit more muted as I've got the Q4 and no mods. One thing that I think I noticed, could be placebo, is that even in Dynamic mode the car felt smoother... less herky jerky starting and stopping. Probably in my head though.

 

How did you bypass the SGW?

 

Using an SGW bypass from EuroCompulsion. Here are my instructions on modifying it to allow communications to not only the ECM but the other modules in the vehicle as well: https://www.giuliaforums.com/threads/multiecuscan-anyone.45717/post-784479
