Link ECU Injector firing problem
Greetings from Singapore. I currently have a FM Link ECU Mk2, running 550cc RC Engineering injectors.
I've recently been having problems with my Injectors. For some reason, the sequential injector modification that I made to the car stopped working (4th cylinder injector stopped firing, there was no current in the wires. I checked the wires I had run for the sequential mod from the ECU to the injectors and they were fine.) and the 4th cylinder basically blew. After re-building my engine, I re-wired the injector harness and then ran batch firing for awhile (4 weeks) with no problems.
However, recently, I have been having trouble with starting the car, which was traced to an injector problem. Basically, the 4 injectors are firing almost non-stop and the cylinders are flooded with fuel and the car can't start properly. I'm in the midst of checking the wires, but I'm worried that the ECU might be faulty now. Has anyone had any experience with Link ECUs failing like this?
Also, the handheld controller boots up fine, but sometimes when I scroll to different screens, and then I press the edit or adjust keys, the screen shows gibberish and continues showing it. Most times, the gibberish goes away and the display goes back to normal if I press the upper left corner of the handheld controller. Is this just a keypad issue or is there something more significant that I should worry about?
Lastly, if all else fails, would anybody happen to have second hand Link ECUs lying around that I might be able to purchase directly?
