New information
i took some screen cap with my fluke today , there was the result:
the crank sensor only :
the crank sensor in blue and the Map sensor in red:
the crank sensor in blue and the injector :
the crank trigger is constitute of 18 tooth ans one of the teeth is wider than the other just by the half , is very difficult to see the difference , there's no cam sensor on the ATV . the stock computer open the injector only in the admission stroke and the coil is fire 1 time per 2 rotation , how the stock computer know in which cycle is it without cam sensor ? i read the variation in the map sensor to know in witch cycle the engine was. we done some test , we add 10 feed of hose to the map sensor and the ATV nearly didn't start and the engine kick some time and not running so good.
is really looking to utilise the F/IC for many installation on ATV because the only other product available is the same price of the F/IC but it only control the Fuel .
