I was just thinking about the old Link Piggy manifold. The one with the extra injector bungs welded in, and the flimsily-mounted fuel rail that usually didn't spray fuel everywhere and set your car on fire.

Horray google. They had more at one point. The one for your car was last listed a few days ago.

This guy
The pieces of U-channel were my Home Depot Racing aux-injector delete after I got a real ECU and real (well, semi-real, they were RC 550s) injectors.
The tabs broke off on my fuel rail, but it never sprayed fuel on me. Used it for 5 or 6 years.

Would you run staged, or have stock ECU run the stock inj for testing and a MS run a second, full size set?
Why couldn't some of the great fabricators on this site be able to modify a manifold for you that could utilize a stock rail?

What about putting in larger injectors and the having a swith-able AFPR in parallel with the stock 60 psi one in the tank. Then, when going back to to the stock ECU, you would run the larger inj at lower pressure. Sure pattern would be bad, but if the ECU could make them work, it would be simpler than changing or adding injectors.

Simpler than changing injectors? It takes 15 minutes tops.
But even if Joe doesn't want to bother with that, I'm still curious why a parallel or piggyback install wouldn't work. Have the MS control fuel and timing and the stock ecu everything else. As long as you can mimick the stock ecu settings, and Joe has before iirc, and even got a car to pass with ms iirc (or was that y8s?). I mean if it was some n00b it would make sense, but Joe knows his MS and knows his electronics. I'm sure he could make it happen.

I have been told, by people whose opinions I value, that trying to keep an NB ECU happy in a parallel environment, in which it is not in control of the primary injectors, is difficult bordering on futile.

You'll be getting CELs, yes.
Also, forget what a happy idle is once you hand over the ignition control to the MS. The stock ECUs uses it for fine idle control and unless the MS controls the idle valve (another CEL there) you can expect idle oscillations.
That's my experience on my 2002 with a parallel MS1 setup.

There is already a thread about passing OBDII with an MS3 in parallel.
It ended with success and rethinking life under the influence if many stiff drinks. The experiment was discontinued due to intervention from ethical watchdogs from the future who came back in time to tell me to stop pursuing intellectual dead ends for the sake of convenience.
Anyway, the piggyback is a cool concept and with the proper rear mount turbo, could be a real stealth option.
However I still stand by my challenge to you of a mechanical computer fuel injection system. I suspect anyone who attempts to evaluate this vehicle will pass you out of sheer awe.
