GeeEmm Posted April 18 Report Share Posted April 18 Hi all, appreciate some guidance on a couple of issues. 1. Download map from G4x. What is the procedure for downloading the current operating map in my G4x? I tried it a few weeks ago, and couldn't find anything on my computer when I opened the software. At this point all I want to do is familiarise myself with the software, and how my unit is programmed, not planning to tune. 2. I have a Solo2DL set up for serial connection to the previous ECU. I have a Powertune dash connected by CAN to the G4x. My Powertune dash will be used to display gauge-based data (temperatures/pressures etc), but I want my Solo to continue to act as lap timer/data logger, and use the RS3 software for analysis. The Solo can operate on serial and CAN connections, so my two questions are: can the Solo be plugged into the currently functioning Link<->Powertune canbus connection (I am assuming the answer to this will be 'yes'), and so how to do this - is it as simple as identifying the two canbus wires, and splicing into them? Is the connection parallel (high to high, low to low), or serial (ie create a single loop)? Assuming a successful connection, can I expect the Link interrogate the new device and recognise it, and provide the requested data, or should I expect to make some introductions between the two to enable the connection to transfer the data to the Solo? Although I have had programmable ecus for a couple of decades, I have treated them as black boxes and left the tuning to the wizards, so my familiarity with their workings is low - please keep your answers at 'village idiot' level Thanks in advance! Ed If it helps, car is Mazda MX5 msm, Link is G4xpnp. Quote Link to comment Share on other sites More sharing options...

Open PClink, connect to ECU (F3 or ECU Controls -> Connect or click on the red box in the top right that says Offline), File -> Save as... If you want to play in PCLink without connecting an ECU you can just do File -> Open and select any of the sample tunes that come with PCLink or any that you have downloaded. 1 hour ago, GeeEmm said: 2.

Assuming the Solo and the Power tune dash are setup to the same CAN Bus Speed (e.g.500kbit/s, 1Mbit/s, etc) and only one of them has a terminating resistor on their CAN bus wiring then they can be wired together and to the ECU. (ECU will also need to be set to the matching bus rate but that is easy to configure, not all devices support different rates). CAN High to CAN High and CAN Low to CAN Low, 120ohm terminating resistor at each end of the bus (ECU has one built in) and no more than 15cm of branching off from the bus. There are pictures and explanations on CAN wiring in the PCLink help manual. 1 hour ago, GeeEmm said: Assuming a successful connection, can I expect the Link interrogate the new device and recognise it, and provide the requested data, or should I expect to make some introductions between the two to enable the connection to transfer the data to the Solo? You will need to configure the Link with the CAN messages you want it to send and receive. You will need to refer to any documentation you have on the powertune and Solo to find this information. Form memory there is some information on how to talk to a powertune dash in the PCLink help manual. GeeEmm 1 Quote Link to comment Share on other sites More sharing options...
GeeEmm Posted April 19 Author Report Share Posted April 19 Thanks Vaughn. The Powertune is connected and functioning, at a basic level at least. The Solo will be 50-60cm off the Link-Powertune bus, and I have so far been unable to find any AiM documentation for Solo-LinkG4x, looks like there may be for earlier Links, or maybe the AiM site is out of date - I will follow-up with the local AiM distributor next week. Is that distance (50-60cm) a deal-breaker? I note the two CAN channels, is that simply a software thing and they both use the one physical set of wires? Or are they wires separately? The next step will be to download my tune, which I will do over the weekend. Thanks again for your assistance! Ed Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 20 Report Share Posted April 20 For the solo2DL set the ECU stream in RS3 to Link CAN BUS BASE. The CAN bus should be a trunk of twisted pair with any stub off the main trunk kept short. You can do it like this: Or I often find a "daisy chain" type variation easier so there is effectively no stub at all, something like this: GeeEmm 1 Quote Link to comment Share on other sites More sharing options...
GeeEmm Posted April 20 Author Report Share Posted April 20 Thanks Adam! The top layout isn't workable for distance reason, but bottom ok. As the Solo will be only an occasional fixture (dual duty car), I will need a bridging plug to complete the circuit when it is absent, that should be straightforward I assume? So there will be a plug, probably in the glovebox, with a bridging plug linking the two Can High and two CAN Low terminals. When installed, the Solo will have a cable run of four wires (two CAN High, two CAN Low) - will they be two twisted pairs, or one twisted quad?

Adamw Posted April 20 Report Share Posted April 20 No bridging needed. Consider the box I have marked "solo" on the pictures above as the CAN connector somewhere near your solo. You will have 2 CAN H wires crimped into the CAN H pin (1 in and 1 out) and 2 CAN L wires crimped into the CAN L. The bus will be continuous whether the solo is plugged in or not.

lim327.ap2 Posted April 21 Report Share Posted April 21 Hello Ed, I just wired in my AIM Solo 2 DL a few weeks ago, and stumbled upon your post as I was searching for the same AIM Solo - G4X documentation haha. If you already contacted AIM, would you mind sharing what you found out when you hear back? In the mean time ill continue to research, and if ill chime in here again if i have any leads Quote Link to comment Share on other sites More sharing options...

ECU setup is in the help file. Quote Link to comment Share on other sites More sharing options...
