We are just about ready to install megasquirt on Mugs 2.4/GT35R street car.
I only want to make the wiring harness once, so I figure I may as well take full advantage of the megasquirt platform and "add everything" right now, even if we are not using the features currently.
Megasquirt has a feature which allows for dynamic timing and fuel table adjustments depending on how much ethanol you have in your tank at any given time
We bought 1000cc/min injectors, but after thinking about it for a while and doing some calculations they just might not be big enough.
Although COMBINED with the stock 450cc/min injectors we would have enough!
Megasquirt has this neat feature where you can use a second bank of injectors.
I am not 100% sure how it works, but as far as I can figure it activates the second bank as soon as you pass a pre-determined threshold for the first set.
so, in this perfect world, the IDC of the first set of injectors increases until it hits a safe limit, say ~80% then the second bank activates and the first bank kicks down to about ~20%. and then both banks ramp up accordingly.
Advantages:
-better idle because I can use the stock 450's and have the 1000's switched off
-not be limited in the future, it would be easy to buy two sets of 1600's if i ever wanted to go crazy and make mad HP
My question is: What is the best way to go about adding the second bank of injectors?
The fuel and plumbing is pretty easy to to, im not too worried about that.
we have this for the intake manifold:

I assume it would be easy to weld four injector bungs and rail mounts on this bad boy.
where do I buy the bungs?
who could weld me up something like this?
I guess i am going to have to weld them on top, we have AC in this car, along with mounting the cruise control under the manifold.
So much for a clean engine bay!
