Loss of power after engine exchange on Renault Master 2.5 dci
Hello, i have trouble with Renault Master 2.5 DCI 100 after swap engine 2 years ago
The original engine is G9U-650 from 2008 (100hp) and the new is G9U-754 from 2006 (120hp). One mechanic have changed the engine and saved EGR and TURBO from old engine but not the Injectors and Pump. I don't know if the Wiring harness is from the new one from (754) engine or from the original from cars (650) The original turbo from G9U 650 work with pressure from intake pipe (without MAP sensor) is swaped onto the new engine (G9U 754). All of the old parts are in trash can and the ECU from the new engine (754) too The original ECU installed on cars is EDC16C36 Now the problem is the car have a loss of power. The only DTC is from EGR and i closed it (mecanicaly and in dump) and now i haven't DTC. No smoke but the turbo not opening. No intake leak I think the trouble is EURO 3 (754) and EURO 4 (650) I don't know what is the part number from the new engine ECU It is possible to calibrate the injection maps in original dump (from EDC16C36) to work with the new engine 754 ? Thank you |
