BC system shorten all the stock pulses to half to compensate for the double size injectors Injector offset The offset value is a measure of how fast the new injector will open and close in relation to the stock one This is most noticeable at low load idle when the injectors have a short pulse If you know the exact specs of the stock and new injectors it s possible to calculate the offset but this is seldom the case You are left to test this at idle to find the correct value You can start by selecting 0 ms It also compensates for the fact that if you half the injector pulses the idle pulses may be below the time where the injector shoots fuel at all typically 1 ms CIVINCO ENGINEERING AB HILDEDALSGATAN 24 SE 417 05 GOTEBORG SWEDEN TEL 46 0 31 22 08 10 E MAIL INFO CIVINCO COM WEB WWW CIVINCO COM 46 54 BCLabG3 manual Jan 2008 How to tune the Injector size and offset First you specify the injector size relation This will then make sure you have the big picture correct This will make the engine run correctly on high load and at long fuel pulses When you have the right fuel for full load quite often the pulses on idle will be overcompensated so you have to add some offset fuel Normally an injector starts to give fuel for pulses over 1 ms so at 2 ms fuel pulses the engine actually only get 1 ms fuel If the stock idle pulses are 2 ms and you halve it with the injector size compensation the engine will not get
