Hi Guys, I’ve got a EFJL turbo Mira thats running bulk rich. Ive changed plugs, fuel pressure reg, O2 sensor, checked for vac leaks, MAP sensor is good etc. The only thing I’m not sure on is the fuel injectors, I’ve had them overauled but I don’t know if they are correct flow? The guys who’ve had the car before had a 'bigger = better" attitude so wonder if that’s the issue, everything else except the GT1241 Turbo is stock. Any thoughts ?
If it is rich over the entire rev range then I would think of reducing fuel pressure at the regulator
I’m running 2.6 bar atm, anything higher and its worse. Could try 2.0bar and see how that goes but if the injectors are incorrect that could not be px enough resulting in poor atomisation
Ok turns out my injectors are from a charade gtti 1.0 p/n. 195500-1610 and not the p/n 199500-2170 that it probably should run.
I checked the timing is set to 10’ and retried the fuel pressure, missfires bad at 3bar and runs a bit better at 2.5bar
