BMW e46 330Ci TURBO 2JZ running 600rpm idle

First of all, sorry for the quality - i made it using my cellphone. I forced the engine to run 600rpm idle by lowering the rpm target on the EMU standalone settings, just to try it out. Its running pretty well, even though the spark plugs gap is only 0,4mm! The injectors are Siemens Deka 850cc.
