I'm looking at my first dive into the EFI world.
It looks like the MSII is what I'll need to run my 355/nos(progressive/2 stage control.. not feed fuel through injectors /2step/etc
for a hotter than most engine would mass air or speed dense. be a better set up..
#2 how does one figure the size injector to run..
#3 what do most source t/b from ? to mount on a square bore carb single plan

the vehicle is 40y/o the alt is a newer type and I have no noise through the radio.. but not sure if thats a good way to tell if there is any that would drive an efi system nuts..
is there a way to test for an issue here.. painless makes a new harness for my vehicle. but it's not cheap..


thanks for any insight..
I read the manual twice and it's a little much to take in at first, might take a few more reads to get it all..

if I was to fuel the 2 stage happy gas would the msIII with staged injection work better than if I tried to feed everything through 8 injectors..

The B&G code can be set to add a bit of fuel and pull timing using the flex fuel input for nitrous. For MS2/Extra or MS3 nitrous control, see MSExtra.com.

Most of the tuning knowledge and such is going to center around speed density.

#2 how does one figure the size injector to run..

Size for the off nitrous horsepower levels:

How about this one?

Follow good grounding procedures and you should be fine:
