Default Easiest method to pass emissions(plug test) with 97' OBDII Megasquirt?

I've searched and found the parallel method and running standalone? I would like to just do whatever method I have to do and then convert back over to my MSPNP until the next year(unless if there is a better method that doesn't require $1,000,000) .

Current Setup:
1997 Mazda Miata OBDII =(
Stock 1.8L motor
GT2871R (.60A/R)
RX7 550cc Injectors

Thanks in advance to those that are nice and helpful.

Disconnect wastegate arm so wastegate is open (no boost).... put back in stock injectors & maf (if you took maf out)... put stock ecu back in... drive... pass

Or make your own parallel harness and pray you get the rediness checks to go. But seeing as how you are PNP that seems like extra work to make a boomslang when you dont currently have any need for one.

Knowing your location will help. If it's just OBDII, just use the stock ECU and disconnect the wastegate. You may have to do this for a day or 2 and drive it for the stocker to report problem-free (and set your wideband to narrowband of course).
