just_racing Posted July 10, 2012 Share Posted July 10, 2012 Guys in need some help. Recently transplanted an RB26 with an Apexi Power FC into my R32 GTST. Should be just about ready to hit the track again. Put it on the dyno and under load it stalls. We put the oscilloscope on the injectors and found: roughly 12 volts as normal with the switching going to ground at even increments as soon as we start to ramp it up there seems to be a little variation in the 12 volts and the switching down to ground stops happening and of course then it stalls I have sent the ECU away for a repair and they tell me the ECU is in good condition. i have used a GTR wiring loom and am still running the resistors. Anyone seen this before? Ideas on where to start? Any help will be appreciated.

DVS JEZ Posted July 11, 2012 Share Posted July 11, 2012 Try a standard ecu to see if it happens. What other symptoms is there? Link to comment https://www.sau.com.au/forums/topic/404384-injectors-not-firing-under-load/#findComment-6440040 Share on other sites More sharing options...
