New Diagnostic Software for MBE ECU

[EvoOlli]

Or I can make you a special version of the software which will show 100%, if that's enough :-)

Start with a reset of the adaptive maps and have a look at the adaptives on the next miles. If they stay around -10 to 10 it's fine. If they go up to over 30% like in your video there's a problem with the fuelling. The ECU thinks that your fuelling is too lean and tries to enrich.

There's an Android software from Aide, which is different to my software. You should find it in the Cerbera forum.

An alternative is the mobile Unit I've made:

@MrChips: Yes, it's the most recent version. I wanted to implement reading the adaptive maps, but until now I couldn't decipher the protocol of the ECU for doing this. BTW, I have to say I didn't spend to much time in the last year for doing this :-)

@Ian: Yes, every so often I do a batch of some units, drop me a mail and I will give you the information.
Currently I'm working on the next few units.

Thanks for the help Olli. Apologies for asking but do you still make them for people & how much? I appreciate it may be more trouble than it's worth.

Hi Ian,

I have some units ready now, but can't contact you through PN. Could you contact me so I can give you some details ?

Hi Nenad,

you should look in the Windows Device Manager which (Virtual) Comport your USB Adapter is assigned. Then you need to select this COMxx in my software.
Every USB/Serial Adapter will get a new (Virtual) Comport, some adapters even get a different Comport when plugged in in a different USB Port on the same computer ;-)

Cheers

As far as I know: If you have one of the new MBE ECUs from Dom it should have a CAN Bus Connection and for that you need a special diagnostic adaptor. I think Dom will help you with that.

I can confirm that there are cars which have the OBD but no 3pin connector. Some cars have both.
I can give you the pin no./connection info this evening, don't have the documentation here at work.

Why should it stop working ?

[EvoOlli]

The first i would check is the power supply of the ECU. Don't know the Cerbera, but in the T-Cars there is a 'big' fuse in the passenger compartment between the battery and the Fusebox. In my Sagaris the connectors of this fuse where corroded and I had around .5V to 1V lower voltage then the battery, despite the thick cable running from battery to fuse box.
So start to check the supply to the fuse box and the relevant fuses to the ECU. The voltage should be stable.

[EvoOlli]

There should be a regulator inside the ECU, but IMHO it would be 'behind' the input voltage sensor you can read.

Do you have a Voltmeter ? You could for example measure between Plus of the battery and the Supply line of the ECU. Best to do this under load because if there's a contact problem, it will only be visible if there's load on the connection.

Been in holiday, so wasn't able to answer....
