in case that's a serious question its about the AIM SOLO gps lap timer. The main thread on the DE forum is quite long and involved now with sub-threads getting a bit knotted ... there are some irregular 997 specific issues (as well as 996) re the install and config.

HiWind

Got this from Italian AIM tech specialist guru - had to stalk him but some good info for me at least ie don't know much about this stuff, especially GT3 electronics ... -posted as guidance incase plus you gotta love the 'Italian'

Hi Matthew,
I’ve not well understood how things have gone, but even if you program a different CAN driver that do not transmit messages and has the same bitrate, as is the case of these two protocols (996 and 997), you shouldn’t get problems, because we just listen to CAN communications. I’m interested knowing how the DL has been connected to the CANbus, mainly if the original cluster wiring has been damaged somehow or was in short, or too many wires were cut, because it seems that the cluster was isolated by the whole CAN network as the CAN timeout makes me think about.
*
Another point can be that Porsche CAN network already has all necessary termination resistors, if you have connected the SOLO DL with the included 120Ohm resistor (placed at the end of the cable), this might have added an unnecessary termination that has caused this failure. With a voltage meter you can measure the Ohm seen between CAN+ and CAN- of the car before connecting the SOLO wiring, if it is 120Ohm you can maintain the resistor on SOLO wiring, if it is 60Ohm or so, you can remove the resistor from SOLO DL cable.
As a general suggestion if the network is not modified and all Control Units are in place, you can remove the termination resistor on SOLO DL and shorten the cable at your need.

Oggetto: AIM SOLO DL - CAN timeout on Porsche 996 GT3RS
*
Greetings Stefano,
*
thanks for the website and all the great stuff on FaceBook etc.. You are mentioned as one of the gurus in a few place and I've been searching a while. I was hoping you mght be able to help me as I haven't been able to solve this question I have?
*
The question/problem is:
I recently bought an imported*996 GT3 RS and a SOLO DL with it. I connected it carefully - used the manual, web direction, battery off etc.. and only connected the CAN+/- and got it to work so I could see RPM, Throttle etc.. coming through onto the screen. The only problem was when I first attached the SOLO DL to the Harness, I had it configured for Porsche 997 (Siemans ECU) not the correct Bosch 996 ECU (I refer to the config done in RS2 with DL connected to computer).
*
What happened then was that the car's instrument cluster stopped working and even thoughthe DL was working, my RPM, Speedo, OIl pressure etc.. stopped working on the Instrument Cluster. I got a Error reading and on the analysis machine (PIWIS) it came up a CAN Timeout. We ended up having the cluster fixed*but now I am afraid to reconnect my SOLO DL. Can you give me advice on ..
1. why this may have happened?
2. have you ever seen this before?
3. how can I test that my SOLO is not sending out dangerous signal or maybe that the harness is faulty?
4. Any other advice you can give me would be very highly appreciated as these things seem to be quite new to the market and there are few out there who really understand the ECU - least of all me!

thanks very much,

I can't make any sense of that...

All I know is that people have been having problems running a Solo DL on their 997.2 GT3s, and AiM needs to find a solution.

CRex

It looks like Matt had a completely different problem when the Solo connection knocked out his instrument cluster. Some of the cables come with a resistor wired into the cable (my OBD does, my CAN doesn't) which is why the AIM tech said what he said.

If yours work as advertised, congrats and leave it alone. I've had the misery of trying to get this piece of crap to work over the past half-year and at times I just wanna forget the whole bloody thing...

orthojoe

Which ECU manufacturer does the 997.2 GT3 use? Bosch or Siemens?

HiWind

I believe 996 was Bosch, 997 switched to Siemens - weirdly aim config software lists Bosch (for 996) along with all the other car makes audi, peugot etc... and under Porsche only 997 ie flips between ecu maker to car manufacturer

orthojoe

Just another data point:

I helped my buddy install his Solo DL through the CAN line on his 2010 997.2 GT3 today. We used the Bosch 997_GT3 protocol and it works like a charm.

HiWind

nice, good for you guys ... but wierd. Can it be the harnesses aren't all stock or the ECUs? I'd imagine the SOLOs are all exactly the same tho but that's just a guess.

CRex

Joe, are you sure that's the Bosch 997_GT3 setting in RS2? 997.2 GT3's all use Siemens EMS ECUs...

AIM is such an f-ed up company that it redefines the notion of f-ed up.

orthojoe

100% Sure. I programmed the solo and did the CAN install. The ECU on this 2010 997.2 GT3 (non RS) was labelled Bosch. I should have taken pictures. I corresponded with savyboy (who has an RS) the other day about some other issue, and he says the GT3s use the Bosch ECU as well. I believe all non-DFI engines use the Bosch unit. DFI gets Siemens.

If you haven't tried the Bosch 997_GT3 protocol on your car yet, try it.

CRex,

I am really sorry that you have had such a tough time with your Solo system. I would be happy to discuss what ever issues you are having and try to come up with a solution. Here is all of my contact information...

Josh, many thanks for reaching out. We'll be in touch next week. Meanwhile I've tried and re-tried the settings, still no luck.

Weird thing is, I have an OBD cable with which I tried to plug the SoloDL into my MB C63. Still no joy--no data readouts whatsoever (that's after configuring RS2 to use OBD2->CAN). Is there a user-serviceable way of diagnosing the SoloDL?

Thanks in advance
