Passing OBD tests with a turbo?
I'm new here and did a little searching but couldn't find what I need.
I'm new to the Miata. Everything I have boosted before has been pre-OBD.
Example:
This Saturday I picked up a loaded '99. I'm looking to add either the FM Hydra or Begi with Xede. Maryland has mandatory OBDII testing once every two years, so I'll need to be able to pass the OBD port test.
My question is this: Which will be more emissions friendly?
I've read both install manuals. It looks like with XEDE a map can be loaded that will knock off the CEL, but for the most part it stays on (the bit in the manual about covering the light with a piece of electrical tape).
The Hydra looks to be plug-n-play enough to swap injectors, ECU, and MAF back in. Could I pin the wastegate open, reconnect the MAF and baby the car around for a few days to get through emissions? In either case a CEL is an automatic fail.
Could anyone offer some advice?
Thanks,
Pat
Sorry for the newb questions.

You could possibly get away with putting the stock ecu/injectors, maf back in, but you wouldn't want to boost at all, and it takes a couple hundred miles for the obd system to fully diagnose everything, otherwise when they test it it will say something like "monitors not ready".
I would put everything back to stock, or just use a piggyback ecu.

The Xede is a good way to go it seems but I don't feel it is anymore capable than a similar system such as the AEM F/IC which can be had for $360 shipped i believe. Then you would just need a PNP harness which can be had for around $100. It runs off MAP and would allow you to take off your MAF when not going in for you inspection testing.
I like the idea of the Xede and the BEGI support should be excellent. I just don't like spending mass amounts of money when not needed.

You could potentially get away with a MS according to Arkmage. He is presently running parallel in his 99 and says he has no codes and has full belief that he can pass OBD 2 testing. The Innovate LC1 will send the factory ECU the right O2 code, and you can leave the maf plugged in and you can cap off the EGR. As long as the electronic components arent missing, you should be fine.
I will be going the same route as him, if it doesnt work then I guess ill have to devise a work around.

I was talking to my mechanic who does the emissions and I am like "what if I bring you the factory ECU running off a 9volt with an OBD plug, but it provides all the proper information for the inspection computer?" He said "if you can figure out a way to do that, no problem".
