I have MD311121 ecu and wondering what injectors the N23 has: 240cc or 275cc.
So, what are the cams duration for N23 4G63? Any help will be greatly appreciated.

I guess since all 4G63 DOHC NT have 240cc injectors, the RVR is no different. I know the exhaust cam is 264* with 8.5mm of lift but I can't find anything about the intake cam.

The RVR shares the same camshaft as the 1994 Galant GS. The service manual states that the valves open @ 63* and close @ 21*.
The 1994 Galant GS intake cam is 260* with 9.3mm valve lift. The GS cams has the same durations as the Euro 4G63 NT but with higher lift: 10mm for the intake and 9.5mm for the exhaust.

I have the same ECU with 240cc. However, its running rich though. With this problem, Im not so sure if this is the stock injector.
