WARNING: Nanocom ACE Bug

[ds23man]

Do not use the function "set calibrated" and "set tested", it will lock up the ACE ECU.

This happened to me this morning with two ecu's. There is also something wrong with the displayed fault codes: pressure sensor out of range will give control valve 2 circuit fault on the nanocom and a unplugged pressure sensor will give control valve 1 circuit fault!!!!!!

Will contact Mattia today about this.

This is the story what happened:

I got the amber warning light after starting, so I took out my nanocom and read the logged fault codes: direction valve 2 circuit failure. Bought a new coil and fitted it, nothing changed, still the same code after clearing. Tested the valves in the output test mode and they worked! Strange. Used the input mode and saw some strange figures concerning the pressure sensor, 200 bar with the engine off! Disconnected the sensor and now I got the direction valve 1 circuit failure, so I scratched my head. Fitted a new sensor and everything worked fine again. Recalibrated both acc. sensors and everything stil worked fine.
And now the part I should not have done: after using the set calibrated and set tested function the amber light came on, main relay switched of and all output test functions did not function anymore! The amber light goes directly on if you switch on the ignition.

So I took a spare ace ecu, did the same as above : same story!!!!!

Found this on the site from black Box Solutions:

New/Used: This identifies if the ECU is new (Virgin State) or used. Before a new ECU can be used the main relay have to be energized, then it has to have the lateral accelerometers calibrated, which can be done using the 'SELF CALIBRATE' function found in 'OTHER' section. It also must pass all 5 'RESPONSE TIME' tests also found in the 'OTHER' section. Until these functions are performed, the ECU as an internal feature will not function correctly and will keep the fault lamp illuminated. Once this has been done this value will change from saying 'NEW to say 'USED' and the ECU will function properly. At the end of the tests, return the main relay to normal.

I think my ecu's went back in the virgin state! Now I have to go to a dealer because the nanocom is missing some functions mentioned above.

Regards Gerhard

PS The nanocom was used standalone.

Hi Gerhard,

I can't really offer any advice to your problem, however I have used the 'callibration' and 'set callibrated' function with my nanocom with no problems - i don't recall using the 'set tested' function though....

In my case i was trying to resolve a problem where the amber ace light would come on for no apparent reason - every once in a while, unfortunately recallibration did not make any difference.

please let us know how it turns out.

cheers anthony.

It happened with 2 good working ecu's setting calibrated and tested, so there must be a bug. And the wrong faultcodes apeared on both ecu's. On a other forum problems were mentioned and also reported to Mattia, but nothing has been done with it. I fear this bug maybe is in the new Evo also. I mailed Matti a couple of days ago, no response! BBS Guy responded with a general answer.

I have the same experince with the Nanocom EVO and "locked" ECU. Also asked Mattia for help. Now the Blackboxs Solutions took over the production, and I'm not sure, if the development will continue, as they have also other products.

[ds23man]

I have been to the dealer today and hooked up the Testbook system: Yes, the ECU is recognized as a New ( virgin) part. Recalibrating failed becaused testbook stopped the process due to logged faultcodes, but there aren't any stored.

1. There is a bug in Nanocom. DO NOT USE SET CALIBRATED AN SET TESTED!!!!!!!!!

2. My Ecu's are ****ed!

3. Some faultcodes are "mislabeled" in Nanocom

Hope BBS will iron out these problems very soon.

Hiya Madtom

It seems the Set tested function in the Nanocom system inadvertently also clears the set calibrated flag, resulting the ECU behaving as a Virgin one.

This will obviously be fixed in the next firmware upgrades.
In the meantime, you simply need to aways to run the two accelerometer calibrations and the set calibrated function after using the Set tested one :thumbsup:

[Arragon]

Thanks, now it works fine.

[madtom]

Thank for the information, I'll try it when the weather ouside permits.

It would have been nice if you mailed this solution to me, the OP. In the moment a used ecu is sent from the UK to me. If you came up with an answer sooner it saved me 60 pounds.

:thumbsdown:

[ds23man]

It worked, my ecu is working again.

What about the wrong fault codes?????

Gerhard

[BBS Guy]

No worries Madtom & Arragon, most happy to help you as i am with almost any Nanocom owner.

And i will definately be looking into those Key issues you PM'd me about Madtom :BigThumb:

It simply seems that for an ACE ECU to report itself as used rather then new, it must have both its "Calibrated" and "Tested" Flags set.
In the function of setting the Tested flag with the Nanocom, the calibrated one is knocked down. Hence the requirement to set the calibrated one afterwards. Therfore this so called "bug warning" is really nothing more than a mis understanding of proceedural requirement.

Interestingly, in our own equipment, we have never provided any such independant and by passing flag setting function.
We simply provide the proper 2 sensor calibration and 5 stage test functionality that seems to automatically set these two flags and thus provides a Used rather than New status.

Fortunately for any owner who is not replacing an ECU for a New one, or an accelerometer sensor, neither function is actually required to be used anyway.

In any event, it will be fixed appropriately in the next upgrade anyway.

I am of course very pleased to have got to the very bottom of this particular aspect, but i have little doubt that other proceedural or functional errors may well exist in the Nanocom software.

It's pretty difficult as the coverage of the Nanocom is in systems and functionality we debugged and got sorted fully near 10 years ago, but non the less I assure all Nanocom owners that we will be doing our very best to track any incorrect functionality down and rectify it as best and as quickly as we can.

Hiya Daryl

Sorry to have offended you, but to the best of my knowledge neither Madtom or Arragagon ever paid me a cent, and if either them or anyone else had just cause to criticise me, i would accept it quite happily and willingly.

I appreciate how my post might seem to you in the lack of further knowledge and understanding, But i assure you I am a decent, fair and honerable chap. My comments were not without due or worthy justification or reason and i only ask you to give me the benefit of doubt in the lack of your fullest understanding.

Warmest Regards

So you where in the Nanocom Evolution deal????

This is my last post here, moderator's who are deleting links to respected newspapers with public information about convicted criminals should watch the news better, dictatorship will not last long. See the middel East!

I dunno this ones lasted 10 years,,

and it IS a dictatorship.
what the OWNER says, goes.

If you dont like it,, ----------;)

No I wasnt in the Evolution deal,more than happy with my Nanocom bought from Rovercraft.
Take your bat and ball and go play eleswhere if you wish.NO LOSS TO US;););););)

Thanks Andrew :)

Land Rover Zone springs to mind as a place this person feels at home.

Collin. How do I tell if my Nanocom has the latest upgrade?

[BBS Guy]

Hiya Mr Whippy.
I am having to assume you mean a Nanocom Evolution as you do not specify.

It is best i do not qoute any specific figures here as the latest upgrade is a relative item.

You need to go to the Nanocom web site, download the latest upgrade provided there and unzip it. Inside you will find a document providing the version numbers which you can directly compare against the version numbers you can get from your unit.

You can see this during the Boot up stages of your unit or by using the Menu option provided which is detailed in the Units User guide.

[d2dave]

Thanks Collin. Yes it is an Evo. Purchased around August last year(2012)

[BBS Guy]

Then the advice i have given is correct Dave and if you have not upgraded the unit then you should do anyway.
