Problem with tune megasquirt
Posted: Fri Jun 03, 2011 8:58 am
Hallo. First i want sorry for my English and please write to me only simple word.
I have Megasquirt 2v3 on my Car. It is Fiat 126p preparing to sport. Engine in this car is:
Four stroke, Displacement: 700cm3, Two cylinders, Power about 40 HP, I add to this engine one injector from FIAT cinquecento/seicento.
I have VR sensor on trigger wheel 60-2 teeth, IAC stepper Magneti Marelli, two spark coil. My problem is tune this configuration.
When i tune ingnition at 60 teeth (correctly to this engine) engine doesn't start properly (have to low rpm and off) but when I tune ignition at 30teeth (I have twice rpm) engine works good but in high RPM (about 5000 in engine 10000 in Megasquirt) my coil doesn't have energy to inuce spark( this is naturally because it must induce twice spark). Why my engine doesn't work properly on correctly configuration? Problem can be on my IAC stepper or on cable from VR sensor? please help me. Sorry for my English.
