and MS-II extra has dual wideband

I use an emulator to "burn chips", and Zcontrol to alter ROM images. I don't have to burn a chip, and I don't, until I've got a tune that I like. It's not like it's megasquirt or bust for doing retunes with a laptop.

edit: and SAFCs limit the size of my AFR map, so why would I run one?

If I were to go with an aftermarket ECU, I'd probably use the AEM EMS plug-n-play (uses the same harness as the stock ECU).

You only use and SAFC when you don't have access to an actual method of tuning. They are a bad idea outside of minor adjustments as alterations to your expected AFR vs. actual AFR can also alter the relationship to the ignition maps which can be more dangerous or hinder performance.

There is nothing wrong with reprogramming the stock ECU, especially if he has the ability to adjust the scaling on the MAF's and injector sizing. The Nissan ECU is pretty versatile, so going with stand-alones isn't necessary unless you are drastically changing the method of induction or ignition system or have performed such extensive modifications to the engine that the factory ECU does not provide enough resolution to support the engine acceleration.

I just played around with the plug and play on my friend's SR20 swapped s14.5, and it's a pretty sweet setup, although it's a bitch to tune since you have to set up everything as opposed to a stock ECU that already has shit like idle enrichment, tip-in, engine braking fuel cut, and all that driveability shit and you just have to play with fuel and timing. The shop that built his car didn't set up fuel cut on engine braking, the tune was real rough for cruising, wideband feedback wasn't enabled, and the car still has no IAT sensor

you wouldn't. I'm saying, you've got one daughterboard to reflash the stock ROM, a separate computer piggybacked to control the boost, and you're talking about adding yet another computer to send a MAF signal to your ECU, that's already enough of a PITA, and it's a good thing that you DON'T have the extra level of complexity of having yet another separate thing controlling fueling/timing.

I don't have a MAF translator, I can just add a bigger MAF and recalibrate in emulated ROM

I'm thinking of a Q45 MAF sensor will be the way to go.

All I've got is my WBO2 (not connected to anything but itself), and my HKS EVC.

I think the flux vapors from soldering has ruined my brain.

I think you will find the stock ECU very hard to beat in terms of fuel economy and drivability, particularly if you're trying to do it on the cheap. Obviously absolute power should be practically identical no matter what computer you use as long as you've got full control over the fuel and timing, and it sounds as if that's not a problem. Nice work by the way.

Hey I got an idea, paint it silver! tbh i'd have another red car in a jiffy for a weekend toy though, not a dd. Even if it's some geo, but bright red, it makes me look every time! So for better or for worse... Some cars are a sin in anything BUT red. Anyway there's my ammends <3
