iceman_n Posted September 13, 2017 Report Share Posted September 13, 2017 Helloi am new to link ecu's, i am experienced but on another ecu brand...i have a couple of question about trigger type and trigger signali am building a Fiat engine that trigger pattern on crank and cam is the same as subaru old models...thats why i am thinking to go for a link ecui post a crankshaft image from the fiat1) is it possible to run subaru 1-6 trigger setup but without the cam signal ? (i just want to keep it simple with wasted spark and batch on injectors)2) is it possible to share the signal from fiats reluctor crank sensor to both fiat ecu and the link ecu as i want to keep fiat ecu to run the dashboard with the canbus etc ?

Adamw Posted September 13, 2017 Report Share Posted September 13, 2017 The subaru trigger mode will need both crank and cam sensor to be happy.Sometimes sharing trigger signals can be a problem and you often wont know until you try. Some OEM ecus will have a pull up or some capacitance etc in the trigger circuit that will distort the waveform too much to allow it to be used. Sometimes it will work fine at low RPM then become a problem at higher RPM.Our Kurofune ECU is designed to be more compatible in this scenario as it has "differential" trigger inputs but it would still be difficult to guarantee since it is not a common engine.Worst case is you will have to attach an extra/independent trigger wheel on the front pulley to run the Link, leave the rear one there to keep the OEM ecu only.

iceman_n Posted September 13, 2017 Author Report Share Posted September 13, 2017 thanks for the quick answer...just check the manual about differential trigger on kurofune...ok thats an option...or i can go totally standalone with just link ecu wired up...and i will use aftermarket rpm gaugebut now the problem is that subaru 1-6 trigger pattern cant work without cam signal....so i need to wire up cam trigger too, i think its the same too with subaru cam trigger...i need to check Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 14, 2017 Report Share Posted September 14, 2017 Yes the cam looks like it matches the Subaru V1-6 pattern. Quote Link to comment Share on other sites More sharing options...
adham Posted June 12 Report Share Posted June 12 Hi is it possible to run reluctor crankshaft position sensor with trigger- and trigger+ to linkecu storm? If yes. How should the wiring be ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 12 Report Share Posted June 12 Is your Storm wired standalone or is it a piggyback like this thread is about? Reluctor wiring and correct polarity is covered in the help file. There are also pinouts and related info for some common engines in the help file section: Wiring Information > Input Signal Wiring > Trigger Inputs > Specific Trigger Applications Quote Link to comment Share on other sites More sharing options...
