Thanks apollard for the advice,
I've followed your posts closely and tried to model my build after yours.
Over the last few weeks I've had a number of setbacks as a result of inexperience and poor soldering techniques. I was able to get the boat started and sounding really nice with a few quick revs in the driveway. Strangely, the engine only seemed to rev up once the fuel pump was disconnected and fuel pressure was close to zero.....
I've got my engine constants setup as follows:
I've entered the injector flows based on the follow website which states: "Flow: OE Specifications - 24Lbs/Hr Flow at 43.5 PSI Fuel Pressure (27Lbs/Hr Flow at 58 PSI Fuel Pressure )"
I'm not really sure why the engine only responds with low fuel pressure.
The other strange occurrence I keep experiencing is the clicking of fuel injectors once I'm done cranking the engine. At this point I've soldered two boards with both boards experiencing the injector clicking. As I've built my engine harness and injector harness from scratch it might be a good idea to map out the harness to be sure I haven't made any obvious mistakes.
I'm onto my third board at the moment, so I'm hoping it's a charm! I guess this means I have to complete another two Speeduino projects with the spare components I have
