Thread: WARNING: Nanocom ACE Bug

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.

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.

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.

Regards Gerhard

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

Thanks, now it works fine.

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