Installing OZ Tuner tunes and Edge Insight CTS2 on our daily-driven Cruze
TAs usual, the aftermarket is here to make our diesel rides better. In this case, we installed OZ Tuner EFILIVE tuning on our 2015 Cruze Diesel to help with the off-idle lag built into the factory tuning and free up some additional power and torque to make the little Cruze much more fun to drive. We took our Cruze over to OZ Tuner in Brownsburg, Indiana, the morning after this year’s UCC competition for Corbin Murphy to upload their EFILIVE tunes to the car using an EFILIVE Autocal interface and laptop computer. While Murphy flashed our Cruze for us—the process is simple and can easily be done in your own garage or driveway in around 10 minutes— he also showed us the exhaust gas recirculation (EGR) delete kit and high-flow downpipe they offer for off-highway race applications with the 2.0L diesel engine. The race parts work with their optional race tuning that can really unleash the beast hidden inside the little diesel engine.
We opted to flash our Cruze with the 30hp OZ Tuner tune file for now, feeling that it would work great for our daily driving needs as well as miles and miles of travel that we do with the car covering events around the country. While driving back home from Indiana we noticed that throttle response was greatly improved, especially off idle from stoplight to stoplight, and the car seemed to pull harder through the midrange as well. The huge improvement in torque at 2,100 rpm on the dyno graph backs up what
he first-generation Chevrolet Cruze Diesel was introduced in 2013 as a 2014 model and sold only for two model years (2014 and 2015) before it was discontinued with the release of the second-generation Cruze and a completely new 1.6L diesel engine. But that doesn't mean we should ignore the first-gen cars. With VW leaving the diesel sedan market, many buyers are turning to the Bowtie for their compression-ignition compact sedan needs.
we were feeling from our seat-of-the-pants dyno. We also noticed a fuel mileage improvement of close to 2 mpg on the highway during our trip from Indiana to Tennessee.
The factory gauges on the Cruze are great for grocery-getter or commuter duties with a large tach and speedometer as well as smaller analog gauges for coolant temperature and fuel level. Digital readouts display battery voltage, tire pressures and DEF level, as well as trip and fuel mileage functions. But there is no way to monitor detailed information gearheads like us want like actual water temperature readings or boost pressure and EGT. Fortunately, the five-inch touchscreen Edge Products Insight CTS2 will work with any vehicle, including the Chevrolet Cruze Diesel, to give more information to the driver. With the EAS EGT add-on kit you can get direct EGT measurements from the Edge probe and the CTS2 will give users a host of PIDS (Parameter Identifications) that can be monitored right out of the box. Edge offers additional sensors and options that can be purchased to work with the CTS2.
Installation of the Edge CTS2 is very simple and can easily be done by most Diyers in less than a half hour in your garage or driveway. The included ODB-II interface cable is routed from the OBD-II port in the car below the dash to the driver’s A-pillar area near the gauge cluster by
carefully removing the necessary trim panels. Reinstall the panels, clean the windshield for the mount, plug the HDMI cable into the CTS2, and the installation is basically complete. If you are installing a stand-alone EGT probe you will need more time to drill, tap and clean the shavings from the exhaust manifold following safe shop practices. Follow along here to see how less than an hour of your time can make a huge improvement in the 2.0L Diesel Cruze with a little help from our friends at OZ Tuner and Edge Products. UDBG
Chevrolet Cruze Diesel is a great little car, but if you want to play on the track or just enjoy a more spirited driving experience and want to keep a better eye on the engine you’ll need help.
