Re: Tech: My take on injectors vs. timing control vs. HP with the stock ECU
The IDC is calculated by using a dwell time constant as well because once your ECU sends the electrical signal to the injectors it takes a while for the solenoid to actually open.
Therefore this amount of time has to be added on and calculated as part of the IDC, and the reason you can achieve over 100% IDC times.
If everyone wants, I can switch it back to calculating it without it.
But basically if you see 100%, you need to up your injector size. Usually it's if you see 80% you need to up your injector size with the regular calculations.
