77 280z l28et ms2 v3.57 help

Hey guys I have some questions I cant seem to find answers too.

Here is my setup

1977 280z

f54 block with a n47 head

megasquirt 2 v3.57 with relay board

stock injectors (soon to buy 515cc supras, but for now I might just bump the pressure with low boost)

280z distributor and coil

stock turbo manifold

stock turbo

msa 2.5" downpipe

Mishimoto 3" intercooler (I don't remember the dimensions but its large)

And I am having my intercooler piping built by mckinney next week.

all I need now is a trigger wheel and sensor.

 

My first question is can I run the 36-1 tooth wheel from diy autotune mounted to the crank pulley and use megasquirt to fire the coil? From my point of view I don't see a reason why it wont work as long as I disable the mechanical advance. 

 

Next question is.. how do I set the timing.. With the 36-1 wheel would the missing tooth be TDC Cylinder #1? I was reading another topic on the subject and he said he was using the 5th tooth but I don't remember..

 

Thanks for taking the time to read this any help is appreciated

For the first question - yes. You can even leave the mechanical advance in place as it will help with rotor phasing.

 

You'd use a timing light to set the timing. Just adjust the Tooth #1 Angle setting until the timing you see on the timing light matches the timing in TunerStudio.
