Feeling slightly underwhelmed...
It took 12hrs today to make my engine fire up.
At 10pm it ran for 10 seconds at idle then backfired when I touched the throttle. The late hour and the rather hektic kabooooooom followed by 250 dogs all barking at once made me decide to pack it in for the night.
I am completely stuffed as to why my carefully written program over the last few months would not work. I could have sworn the instructions say to set up the 4 trigger crank signal and single cam signal inputs in a particular way. This however resulted in two firing events for each supplied home position signal which should NOT be possible in direct fire mode. Before that point I had to replace a Hall Effect home position sensor with a magnetic sensor robbed from a dizzy as the Hall sensor would happily go low all by itself at random times - I may have fried it at some point a few weeks back?? Trying to follow the instructions for timing of the home signal and tooth offset was a nightmare in technicolour with bizarre results for where the ecu would decide cyl 1 should be fired. A good mate of mine came over to work the key for me while I was able then to crawl in and out of the car to the oscilloscope and the timing light etc. After many hours of frustration we put some settings into the ecu which theoretically should not work and then we were able to gradually work out coaxing the timing to within the vicinity of where it should be amid many backfires from both ends... To make things stupidly complicated the halwin software will not show the trigger and home signals in either the diagnostic page or the data logs... The oscilloscope indicates the signals at the ecu plug are fine and dandy but the ecu seems to disagree so I have downloaded the DOS version of the software and dosbox in the hope it may be able to tell me what the ecu is seeing.
So while having the engine start and idle finally is a BIG win I am struggling to get past the bit where the settings needed in the trigger inputs are half what they should be and the tooth offset turns out double the set amount by the time the spark is thrown...
Today is a new day so I will try catch a few zeds and have a fresh look when I awake!
Cheers,
Jason
