In­stalling OZ Tuner tunes and Edge In­sight CTS2 on our daily-driven Cruze

Ultimate Diesel Builder's Guide - - Contents -

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.
