[Ovmsdev] Fasttech production problems?

Tue Jan 20 20:08:43 HKT 2015

I also have unit with no GPS functionality - I am running at least 4 units and by switching with units in other cars I was able to confirm that the problem is in the unit and not the antenna (or power ...)... the CAN bus and the rest of the unit seems to work fine. Since the rest is working and provides the info I really need I have not bothered with the GPS.I got this unit about 5 months ago. Is there warranty?Nikolay

 My unit for the Opel Ampera also lost GPS functionality suddenly. Apart from the fact that the unit itself got burning hot when I touched it. I disconnected it and haven't taken the time yet what the cause might be. My unit for the Roadster works fine, but after a couple of days it will lose connection and the only way to fix it is disconnect and reconnect the unit.

On the spanish twizy forums we had also someone with a gps issue (no fix). I planned to meet him to try to help and also to try with my antenna but had no chance for now.

It was purchased about three months ago if I remember ok.

Michael,

Dry soldering is about the only issue we've ever seen in any numbers over the years. It is frustrating because we group the batch sizes up (making hundreds of modules at a time) so that we have enough quantity for machine soldering, but still the quality sometimes is not there. The 'fix' is normally 15 seconds under a hot air re-work station.

Not sure about the GPS issue. That functionality is mostly inside the SIM module itself, with only the antenna connection external. I didn't get this module back, or hear of this before. Do you know if it was resolved?

Regards, Mark.

 Mark,

 thanks for the info, I'll forward the stock info.

 "More" is relative -- there was one guy whose mod ule hadno GPS a few weeks ago, and I just had some headache diagnosing a module that got stuck every once in a while on CAN writes -- I told him to check for bad contacts and he found a poor soldering point at the CAN transceiver and fixed it himself.

 So, no high numbers in any way, just more than before in my perception.

 Michael

 Michael,

 Fasttech is just the distribution point - they don't deal with the manufacturer. We've used the same module manufacturer since the v2 hardware was first released, and are very happy with them.

 We're currently out of stock of modules, and have a new batch in production. It takes a little longer than normal at this time of year, due to the Chinese New Year holidays. Our manufacturer is f ine,but things like the PCBs are sub-contracted out and these sub-contractors are busy. The modules should be back in stock within the next 7 to 10 days.

 We're also currently out of stock of lefty OBDII cables. A year or so ago, we identified a manufacturer for cables that we really like dealing with. At that time, we tendered out to half a dozen factories, and the one we eventually chose came back quickly and efficiently with a very reasonable price (not the cheapest, but the most professional and reliable). Since then, we've used them repeatedly, and every time they do the job very well. The order has gone in, and the lefty cables should be back in stock within the next 7 days.

 Regarding hardware failures, I've had one RMA replacement last week - but that has been the only one for months. I think there were 3 replacements in total last year. That said, I think people like Pierre are handling some repairs locally for us, and I don't get to know about th ose.But, from my point of view, I'm really happy with the current hardware reliability, and no big issues found.

 Gotta say that most reports of hardware failure end up to be a username/password typed incorrectly, or SIM balance too low. The FAQ I put up on www.openvehicles.com helps tremendously with that (as it forces people to check each parameter, like a check-list, and most notice the mistake then and there).

 Regards, Mark.

 Hi,

 according to a Twizy user the module is currently not available. The Fasttech support told him they've got problems with the module manufacturer (I thought that's Fasttech itself), and they're searching for a new manufacturer.

 There have been morereports on hardware failures lately, maybe that's what they mean?

 Any background info on this?

 Regards,
 Michael
