I own a 97 Miata with a FM Voodoo 2 turbo kit (gt2560r/stock motor). Car is running 12 PSI on 320cc injectors with a voodoo and an msd tuning box, 8 degrees BDTC static timing a yonaka (comma bro) catback and a test pipe. It wasn't my choice to go odb2 but I happened to trade it for my e30
The car runs pretty well, idles smoothly and the AFRs go nicely to around 10-1 @ 12 PSI but the car will eventually throw a code for bank 1 mixture
and one for lack of a catalytic convertor.
I have a year to get this thing inspected, which means having the car set ODB2 readiness. As much as I understand going megasquirt cures cancer, it just won't work in my application at the moment. I may decide one day to swap back and forth with MS only for inspection time. Considering I live in an urban apartment, swapping the drivetrain in an ODB1 shell is out of the question.
As I see it I have two possible options:
1. Run 305cc injectors, from searching the forums these seem to be within tolerance for the dme to adapt to but will they handle the 12 PSI or will I have to back down? What can these typically run?
2. Pick up an AFPR
and dial down the fuel pressure ever so slightly to where the amount of fuel is within the DME's adaptability for a week before inspection. Stay out of high boost, let the car set readiness, turn it back up, profit.
3. Move to south carolina and forget having a full set of teeth because no ODB2 inspection?
I forgot to mention I've already picked up a magnaflow 2 1/4" high flow cat, but don't want to install it before my fueling issue is sorted as I'm afraid I'll brick it prematurely.
Thanks in advance!
