Megasquirt would be the piggyback I believe, educated guess. But your comment makes me wonder, wouldn't a carb be more affected by altitude/weather than efi? EFI like megsquirt has to be able to compensate for those kinds of changes using all the sensors it comes with, or am I wrong here?

i think you are correct but in my exp with MS is all vw based. (all vw's that run like shit anyways) the ECU seemed to have trouble with the weather on the west coast. when tuned in the summer, the cars wouldn't be as smooth in the winter and vice versa since we get some decent weather swings and temperature swings in a single day. theres a joke that washington is the only state that you can use the heater and the AC in the same day.

it was far worse with motors that ran ITB's but thats a different issue.

really unless you need to ADD fuel you dont need a standalone or even MS. a simple afc to take out some fuel is enough. and since i presume you arent going to go with a blower, you wont need that level of control.

my other gripe is i hate wiring. so me, i would run that frontier ECU or whatever plugs in nicely

The plan is to add the OEM blower in the future but that's way off. Just an FYI, I am not going for magazine numbers, just building a fun street truck. The dyno is going to tell me I wasted my money and I'll agree preemptively, it will still be fun and what I lack in power can be made up in gearing and handling. It's just how I build things, OEM parts perverted to work for me. I imagine the VG33ER has to be fun in a 2800lb truck vs. the 4500lb pig it came out of.

yah then i wouldnt bother doing anything other than a factory ECU. its really hard to have variances in boost pressure with a belt driven source.

It all boils down to what floats by me on CL and in the junkyard. I always play my builds by ear when it comes to amassing parts. Maybe I will be lucky one day and entire SC Fronty will be sitting in my favorite U-Pull-It.

That's pretty easy. Ive seen blowers with blowoff valves. All you need to do is vent the air somehow.

Knowing how I operate I won't be running the SC in its stock configuration but I won't know until I have one in my hands ready to install. One day, I need to get a few projects out of the shop before this is even in the back of my mind.

believe it or not there was little support in the aftermarket for those factory blowers. basically a smaller pulley at the blower was it. a buddy of mine had an xtrerra with that motor.

he said it was still slow even with the smaller pulley. but i think thats cause of how much car there was to move.

That's the only thing I found when I had my supercharged frontier. It was underwhelming but there's a lot of truck there.

Yeh, there's quite a weight difference there. Combine that with tire size/weight and axle ratio and the math all points to Nissan missing the boat by not dropping the ER in a true 2wd truck, Desert Runner doesn't count. Green is sitting at roughly 2800lbs with everything I took off it over the years, that should wake that SC right up.
