Thread: New update comming for Nanocom EVO

My current (continuing) saga is the continuous shutting down or freezing in gauge mode. Get about 5min if lucky and it shutdown or freezes the screen and needs to be restarted. I recently had cause to disconnect the battery and for the next 6 days had faultless operation and on the 7th day it reverted to it's uual operation. Any other mode it will sit there happliy running.

Hiya clubagreenie.

Sorry to hear you are having trouble with your guage mode.

Is yours a V8?

Yes. Have been trying everything I can think of. Would supplying power via the power socket possibly overcome it? I was thinking its a power or earth issue in the OBD port, or is there a pin I should check for power/earth?

The other thing I thought was is there a memory issue it could be? Just that when it was powered down for a few weeks when the auto was replaced it came good as well. Does it loose any saved info and then fill?

I had trouble with mine communicating with the SLABS and after sending it back to BBS and testing fine they sent it back with a suggestion of using 12v feed from the lighter socket, did this and things work fine, mate it couldn't hurt to try it with yours

supplying additional power and ground is certainly worth a try as indeed Markndeb states, you have nothing to loose.

Power is on pin 16 and earth on pins 4 and 5 of the OBDII socket.

But when you measure it, you should have the Nanocom connected to supply the load and be aware that this might not show you any intermittancy.

Your memory effect seems very odd too. I don't know of anythi.ng it stores that could do this. Could it be coincidence.

Try a battery disconnect and see if you can replicate it

I know if I leave the battery disconnected for a minimum of four hours it resets the effect for 6 days, any less time disconnected and it stays the same.

If I run a couple of logging multimeters on a circuit between 16 & 4 and 16 & 5 to isolate which circuit has the fault and then log that circuit on both +'ve and -'ve sides independently for continuity it should get it down to showing if it's a supply/earth fault and where it is right?

That is indeed correct clubagreenie, but simply supplying a more direct power and ground via the DC socket would initially prove this to be a supply issue as opposed to something else.

And i have to say that from your very concise and much appreciated replication and report, the affects of your power disconnection and noted results does point to this being something else that is very borderline

Although my Nanocom dev tem are clearly currently fully focused on developing the CAN bus stuff, which would be unfair to distract them from, when this is done i will return their focus to all possible problems and bugs that have come into light on the existing coverage.

If in the meantime, you can rule out all other possibilities, i would happily have them add a few delays in the V8 Motronic gauge mode software and supply you with a test copy to see if this sorts your problem out

Would anyone know if this update will give more functionality for the pre-canbus vehicles? Colin mentioned more options on the p38 BECM, but does that exclude pre 98 (non canbus) BECMs?
