Hi. I'm preparing for a mot test in the near future. This means I started thinking about my injection again.
I have a wasted spark 4 cyl.
Now running Semi sequential with injector table h(0) 0 set to 9 and 1 set to 6. This means 1&4 and 2&3 are paired.
My Peugeot trigger is 60-2 and trigger is 120 deg BTDC so I set trigger settings like:
TDC after trigger (deg) 60
Number of teeth 58
Trigger tooth 10
Next trigger 30
This means in my config the injection starts 120 deg BTDC.
The following post (rob) is confusing me a lot.
(((Stick with the crank sensor alone for the time being. You set the injectors to fire sequentially but they will not be in phase with the engine, but this does not matter as long as you inject when the inlet valve is closed. The inlet is closed when ever the coil is firing (as the cylinder will either be on its ignition or exhaust stroke) so in the case of a 1, 3, 4, 2 engine
Ignition occurs: 1&4, 2&3, 1&4, 2&3 ... so injectors will fire 1, 3, 4, 2 ... or as you don't have the sync pulse from the cam the engine may be firing in the sequence: 4, 2, 1, 3 which isn't a problem as the ignition still remains: 1&4, 2&3, 1&4, 2&3 and the injectors will still fire onto closed valves.)))
When the cyl 1 is ignighting, cyl 4 is traveling down to and in inlet so the inlet valve is open.
