So trying to figure out the values on nisune for my sr20 on 350z coils.
From what i found 350z guys run 5.0ms-5.5ms of dwell time.
stock sr20 dwell is 1.9ms? can anyone verify. its for s14 sr
so im going for 5 is divide that by stock 1.9 get 2.63 than i multiypy nisune values by 2.63 here is what i got.
Can anyone on nistune confirm or has better values? The changes were not to much.

I would suggest starting around 3 and increasing from there. There is no reason to have large amounts of dwell time unless you have a crazy setup. I have 3 or 3.5 on my 500whp VE and a .22 gap on the plugs if I’m not mistaken. My setup is mild though.

Shooting for 400whp on built sr20 on gtx2867 I talked to Matt from nistune and got it all figured out I think I am at 3.5 ms as well
