The Solo DL is one of the latest Data Acquisition (DAQ) systems from AiM. What is a DAQ? Simply put, DAQ systems record lap times and vehicle data for analysis that can be used to improve driver performance. Calling this a lap timer would be missing the plot and is likely to get you scratched off of AiM’s Christmas card list.<\/p>\n\n\n\n

The market offers many outstanding entry-to-mid-level DAQ products from companies such as AiM, Race Technology, RLC, and Traqmate. After an exhaustive amount of research, I selected the AiM Solo DL to be used for my personal development and for the development of the drivers on my endurance racing team.<\/p>\n\n\n\n

The AiM Solo comes in two flavors. The regular AiM Solo ($399) uses 10 Hz GPS and internal accelerometers to return accurate vehicle speed and location data on track maps already stored in memory. If a track map is not already in memory, it can easily be added from track manager software, or a custom track map can be created, even if the “track” is a circuit around your neighborhood. The Solo features predictive lap timing and has a screen that can be configured to show only the information the driver wants. The AiM Solo DL ($699) adds the ability to record ECU information from the OBD-II port.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

I backed-into my choice of the Solo DL by first choosing AiM and specifically, their Race Studio 2 software. AiM is a leader in this market and their products are widely used by amateurs and professionals alike. A significant selling point was that Ford Racing uses AiM systems on its Boss 302R and 302S race cars. It is one of those MLX (digital dash) systems that I really wanted.<\/p>\n\n\n\n

The Boss 302 does not come with oil pressure or temperature gauges and I do not like the Laguna Seca gauge pod that sits on top of the dash. Since I don’t need those gauges on the street, I liked the idea of having an MXL dash to use for the track, but which I could remove for daily driving. Unfortunately, the MXL is out of my price range at the moment. So, I chose the new Solo DL, which has all of the data acquisition features of the MXL, but which does not accept analog inputs (the oil pressure and temps that I wanted). In truth, those extra gauges don’t have anything to do with the primary function of the DAQ. It is simply a way for me to get those things displayed in an acceptable way. I can’t help but point-out that the Corvette Z06 ECU logs oil pressure and temp. If that were the case with the Mustang, I wouldn’t need an expensive MXL dash, I could just display those on the Solo. [shaking fist] “Ford!”<\/p>\n\n\n\n

The Solo DL does everything I need to use it as a tool for driver feedback. If I ever upgrade to an MXL dash system, I will not have to relearn new software and I will still be able to review and compare older data with new.<\/p>\n\n\n\n

I called Jeff at Optimum Motorsports<\/a> and he spent a lot of time on the phone with me answering my questions about the Solo DL. He also had geeky information about the Boss 302R ECU that I found interesting. Jeff knows his stuff. I was sold, so he sent one out right away.<\/p>\n\n\n\n

First Track Test<\/strong><\/p>\n\n\n\n

I had a chance to test the Solo DL just a couple of days later at the 2012 Texas Audi Group State Meet track event at Harris Hill Road. I didn’t have time to mount the Solo (see below) for the track event, so I just plugged it into the OBD-II port, turned it on, and stuck it into the Mustang’s cup holder. I wouldn’t be able to see my lap times, or see the predictive lap timing function in action, but I was more interested in just collecting data for armchair analysis after the event.<\/p>\n\n\n\n

Even with my hillbilly installation, the Solo DL worked beautifully – knowing when the car was on track and then quietly gathering a metric ass-ton of data that would eventually be used to condemn my driving. Since it was being powered through the OBD-II port, I had no battery concerns and just left it on all day. I could have checked my lap times at the track, but I was instructing and otherwise enjoying myself, so I couldn’t be bothered. I love that the Solo can be such a zero-overhead device. With very minimal setup, it can be turned-on and chucked into the glove box. At the end of the day, it will still return Apollo 11 levels of telemetry.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

At the Bonneville Salt Flats<\/p>\n\n\n\n

Since that initial track event, the Solo has been with me to several track day events, a 24-hour road race, and on the Bonneville Salt Flats. In every situation, the Solo DL performed beautifully.<\/p>\n\n\n\n

Data Analysis<\/strong><\/p>\n\n\n\n

When I got home, I downloaded the data into AiM’s Race Studio 2 Analysis software.<\/p>\n\n\n\n

As someone who makes their living as a QA Engineer in the software industry, I feel qualified to say that AiM’s Race Studio software could use an interface update. There is no doubt that this is flexible and powerful software, but it’s ugly and a little crashy.<\/p>\n\n\n\n

Also, there is a very steep curve to learning the analysis software and I haven’t even begun to scratch the surface. It seems clear to me that I will need some training or at least some good tutorials to get the most out of this software. Still, while just fumbling around I managed to find interesting information that I can put to good use. I can see that I’m faster without traction control on. That’s not surprising, but I can point to the data that proves it. I could also see that I wasn’t braking hard enough. That also wasn’t surprising to me – I was on stock brake pads and I was being gingerly on purpose. Finally, I could see that on my fastest lap of the day, I was actually down a whopping 5 mph on the fastest part of the track, compared to another lap (which I must have botched at some point).<\/p>\n\n\n\n

Mounting the Solo<\/strong><\/p>\n\n\n\n

Note: This applies only to an S197 Ford Mustang. I can’t verify any other application or platform.<\/em><\/p>\n\n\n\n

The Solo comes with a metal mounting plate which can be screwed into the dash, attached to a suction-cup mount, or otherwise mounted to the car and then the Solo attaches to the plate with magnets built into the back of the unit. Securing a mounting plate in a race car is no problem, but for my daily driver and track-day car (Boss 302 Mustang), I wanted a temporary mounting solution. A windshield suction-cup mount is an obvious first choice, but I don’t like those because they block my view and I’m not a fan of the lick-stick attachment process. Also, I have had a suction-cup mount fail during hot laps, which left my camera swinging from its power cord, getting smashed to bits against the bare interior of a race car. So, I wanted something temporary, that attached more securely than a suction-cup, and was easily visible\/accessible without blocking my view through the windshield.<\/p>\n\n\n\n

After a bit of daydreaming and research, I gambled $20 on an iGRIP powerPort Mount (1599)<\/a>. The new Mustangs have a power outlet mounted at the very top of the center console and the iGRIP is designed to plug into the power port and hold a cellphone or MP3 player at the end of a flexible arm.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

The iGRIP Mount<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

I cut-off the mounting tabs on the iGRIP, which left a flat mounting surface. The Solo mounting plate is on the left.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

I stuck industrial strength Velcro on both mounting surfaces.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

The finished setup.<\/p>\n\n\n\n

The iGRIP Mount has worked perfectly, even in very rough conditions. The Solo is very easy to read and does not appear to move or vibrate while driving. Still, I will probably reinforce the base to help with stability. I don’t want to torque the power port too much.<\/p>\n\n\n\n

Conclusion<\/strong><\/p>\n\n\n\n

The Solo DL is an excellent device at a class-leading price point. The unit itself is sturdy and well-built with a healthy feature list, all backed by an industry leader. In my mind, this is the current champion in the crowded mid-level DAQ market and the AiM Solo DL comes with my highest recommendation.<\/p>\n\n\n\n
