Please help correctly adjust my engine .
Hello I have a 2012 Jeep Grand Cherokee Overland with the 5.7 engine. I installed the engine from the Jeep Grand Cherokee 6.4. But " Diablo intune DSX", can not correctly adjust the amount of fuel and ignition timing (angles jumps) , adjustment of switching-on the cooling fan not work also ! I need technical support. Do you have the opportunity to more accurately adjust my program because "CMR Custom Tuning Products" and "Diablo intune DSX" can not do it!
