„Ok here is how I chose my map... I have an ELM327 and the app Dash Command...So I tried map 10 no big difference...Map 9 and 8 Gave me a bit better economy... Map 7 Real difference... In economy and torque.... The engine feel like free spinning... On a flat road that I am used to drive... The throttle is open @ 12.9 % to 13.7% @ 1800-2000 RPM and it keep 100-115 Kmh... The Engine ''LOAD'' is about 55 % and the Engine TORQUE about 15 Lb/Ft... and the consommation is around 3-3.8 L /100 Km... Map 6 and 5 was too much on the power side and kicks in @ +/- 3000 RPM... I'm looking more for economy... Here some picture.. This is not a joke or fake... That 2014 Cruze 2.0L Diesel can go 1300-1400 Km on an 59 liters tank. I did 437 Km on a little bit more than a 1/4 for an average of 3.8 and still have 857 Km to go .... You can use those pics for your pub ... I will please me I did tried with out it ...The engine feel so ''sluggish'' the throttle have to be @ 34.1% to 34.9% the load is @ 63-65% and the torque is 18-20... and the consommation 4.5- 5 L/100 ...On the same road same speed back and forth on the same day.... I don't know HOW you do that ...but keep going guys.... Thanks it worth every $... Here is some pictures from my 2014 Chevy Cruze 2.0 L Diesel... Went from an usual 850 Km / Tank (59 L) to more than 1300 Km... From an average 7 L /100 Km to 4.5 L /100 Km....Thanks a lot guy... As I sais.... ProRacing CR10 worth every $$ and NOt only it is more efficient BUT ALSO MORE POWERFUL...”
