i am tuning a ducati 999R to run IGN&fuel by a microsquirt v3 firmware v3.78 all sensor are giving good readings but it read RPM then fall at cranking so it never starts when i used the 321extra code it showed good steady rpm signal but it gave back fires from air box but i won't run it on extra code because it won't handle dual spark as it will handle it so the problem here is, is it a problem at the .msq file or setting up information at tuner studio failed or the microsquirt needs another sensor to re-sync as it uses single vr sensor on a 48-2 cam speed trigger wheel when i checked the the plugs for spark it gave a good spark at the duration of rpm but it gone off when the signal of rpm stopped and it's my first time to tune with a micro all i've done before was fuel setup by ms 2 on 4 cupras
so i am new to ignition and those stuff and i've read tons of info. on the site and i understand i may have to use another sensor to get it start but i don't know i am not expert , the msq is down there best regards
