Here is the thread in which this question ties to:

https://www.rx7club.com/2nd-generation-specific-1986-1992-17/need-advice-importing-my-fc-taiwan-908192/

I'm trying to figure out how to import my FC to Taiwan. The only way to do it is that it has an OBD II port. The car is currently undergoing a massive overhaul. So this leads me to ask: are there any later model FDs that have an OBD II port? If so, maybe I can replicate the FDs power plant and throw it under my hood.

Parting ways with my baby is simply NOT an option. And I'm sure you guys can relate! I'll bring it in as a track-only or show car if I have to. But before that last-ditch, let me know if this is a possible solution!

Thanks

PS, I searched for this already, so don't hurt me too bad if this has been talked about somewhere I didn't find.

if cars are the same in japan as they were in the US anything after 95 should have an OBD2 port, but i couldnt tell you exactly as we only got FD's till 1995

Easy solution, move out of Taiwan

Nope, no FDs came with an OBDII port.

lol. I make too much money here. Plus, the US is a ticking time bomb. About to turn into Greece & Spain x1000 in a year or less once the bailout money runs out.

So CONFIRMED that the 1999-2002 SPIRIT R FDs do NOT have OBD II? I live right next to Japan. I can pick these parts up if I had to! ...& there's no such thing as a OBD II retrofit? Can I make it exist?

OBD-II became a requirement on cars sold in the US in 1996. EOBD became a requirement on cars sold in EU after 2001. While there is a JOBD standard for Japanese cars, I can't find whether or not it's a requirement for cars sold there like what we and the EU have...

Based on the fact that part of the spec is to provide info on emissions, I'm guessing that if it wasn't required in Japan, Mazda didn't add it

There is no OBD II compliant FD. That is why Mazda stopped selling them stateside after the 1995 model year. It also largely explains the engine design change for the RX-8.

i wonder how hard it would be to make an OBDII simulator, either a little box that tells the smog machine everythings cool, or maybe use an ecu out of another car just for the OBDII stuff?

There really is no viable OBD II simulator out there. OBD2 is a clusterfuck. There is more than one physical way to communicate the data (physical layer) and the protocols vary a lot.



See SAE J1850, SAE J1978, and SAE J1979. They explain how some of the stuff about the protocols and hardware layer. But there is a TON of variation across manufacturers that has only begun to be standardized in the 2008 model year, when all manufacturers were required to use a specific CAN protocol.

OBD2 is a clusterfuck? just wait until OBD3 comes out; the eye in the sky will know when you're not wearing your seatbelt and they'll just mail you a ticket

yay, that's how we americans get it done, by being lazier to no contest tickets.

"OBD 3" is an internet forum boogeyman at this point. So far the only real OBD III is the mandated used of the CAN protocol to standardize communication across manufacturers. OBD II was originally a compromise protocol to accomodate pre existing interfaces. Now all the manufacturers have to do some things a particular way.

I have seen ZERO information from SAE about the so-called OBD III, unless there is a new J1979 coming out or something.

I know for a fact that JDM 2002 FD's have a port in the engine bay labeled "Diagnostic". I don't know if it is a OBD2 port but would they test it in Taiwan? It sure looks like it could be one. Hope that helps.

... THEN we get into the whole 'CAN BUS' protocol and EVERY thing goes to ****.

magus2222

iTrader: (22)

can bus systems are the new obd3 just as arghx explained. OBD2 was a clusterfuck. it was a bandaid fix to the OBD1 problem, everyone had their own scanner connector and way of testing the diag system.
obd2 was a good direction to move to, making 1 connector so everyone could scan them, but still there are problems with some scanners not communicating with them IE:corvettes, expeditions, some euro.
and OBD3 was a bunch of bullshit. its against the constitution to be able to track us the way people have claimed.
at the end of the day, CAN/BUS systems are a good way to go until they come up with another less complicated more mainstream way for the engine to be ran efficiently

ive seen fds on the street in taiwan, so i'm sure theres a way

Pm me. I know 4 of them fd owners in Taiwan. They are like the last ones lol.

Car companies didn't stop selling certain car models into the US after 1995 because they couldn't add OBD II data collection hardware, that part is easy. They stoped the importing because of the incriminating information that OBD II would collect regarding real usage emissions. It would require massive engine modifications and turbo charged cars were really hurt. Thus it came down to economics, was the market big enough for that model to spread the development costs over. the RX-7 fell into the NO category.

So do the '92/'93's .. that is OBD I

I think there's a lot of misinformation and paranoia surrounding OBD II and on board monitoring systems. Production cars don't have on-board five gas analyzers or some other method of directly measuring emissions output. There's really three parts to the basic OBD II interface:

1) diagnostic trouble codes--a standard way of checking error codes on all cars, instead of crap like jumpering wires

2) loggable parameters (PIDs aka Parameter ID's) at a rate of 5 total samples per second. this includes water temperature, rpm, o2 sensor voltages, ignition timing, engine load, and fuel trims. see the appendix of SAE J1979 (which I have, PM me)

3) diagnostic monitors to make sure the on board emissions systems work. This includes Catalyst efficiency, evaporative emissions, EGR, and O2 sensor monitors. So the OBD II regulations required that the ECU actually check to see if these systems worked or not, which is why OBD II cars throw codes when you remove the cat or leave the gas cap loose.




What really did the FD in was the new tailpipe emissions standards, called Tier I (current cars must all meet Tier 2 bin 5). Tier 1 was the result of legislation in 1990. see http://www.dieselnet.com/standards/us/ld.php for the Tier 1 emissions standards. Tier 2 came in 1999 and standards tightened up more and more after that. Tier 2 made gas and diesel engines have to meet the same standards, as opposed to Tier 1 which allowed diesels to produce more NOx emissions.

at the time (95ish) mazda had said something about not wanting to redesign the floor of the FD, for the charcoal canister.

you have to keep in mind they imported something like 520 FD's in 1995, and our local dealerships had plenty of new ones until almost 1998!

although looking at the mid 90's cars, they just got a big charcoal canister, and a couple of vacuum solenoid valves, the hardware isn't very exotic.

people who do legal LS1 swaps put that stuff into FC's
