hey, so I'm trying to get a bunch of information on the Yamaha Nytro. I'm gonna convert the sled over to run on the FT450 ECU, but i need a whole bunch of information. I'm just gonna make a list and i really appreciate any help.
Crank reluctor wheel= I've founds some pictures and from what i can tell it's a 24-2 wheel. is this correct?

Fuel injectors= are they high or low impedance injectors? what is the factory injector size? my sled is extremely aftermarket, i bought it that way. so they might be larger. I'm gonna have to figure that out.

crank position sensor= is it a hall or vr sensor?

Coil packs= this is a ft450 specific question, I'm not sure ill be able to get the answer here. but will it run the factory coil on plug coils?

Thanks in advance for any help. any input would be awesome. ill be taking the sled apart to start figuring all this out in a couple months.

heavily and badly modified by previous owner.
 

@rat4020 can probably answer the coil pack & injector information. He runs a Fueltech on his Apex motor.
 
Its a 8 tooth on the apex engine. Not sure if that applies to the nytro or not.

Yes you can trigger almost any COP coil with the FT.

Good luck!
Thank you! i was going off of this picture and one other that i can't seem to find again for the amount of teeth. i figured if i can't get it running I'll probably have to take it apart and count the teeth manually.

I'm using fuel tech FT450 along with the Fuel Tech WB-02 Nano wide ban O2 controller Fuel tech coils and ID1050 injectors along with all the fuel tech pressure sensors . Man Im still fucking with mine, I have a close map but ive got extreme egt temps over 6000 rpms . So before I go any farther Im installing a fuel tech thermocoupler before the turbo and fuel tech ETM-1 so I can program a fail safe limit into the Ft450 before I run any more . Im pretty sure Its something Timing related. Before I installed the ft450 I had the PCV auto tune with the POD screen and stock injectors for like 6 yrs and my only problem was getting a lean at wide open. Hind sight, I should of just added one injector to the air box. that wouldve saved me oh 5 grand. My target boost is 10 to 12lbs. This is my setup
