Hey guys,
I was loaned a Snap-On Super Scanner I want to use to get an idea how my engine and all is doing. Has anyone used one of these- maybe to give me some hints? It has like 12-14 pins on the plug and I don't remember any plugs that big on my RX. Anybody know where to plug in...ICEMARK?
-1989 NA Vert-
Thanks in advance,
Greg C.

 

well ,, since you have a s5 ,, you can jump the connectors in the engine bay. there is a single green terminal. right behind the drivers side headlight. ground that .. go inside the car and count the blinking engine light. a long light equals 10 and a flash equals one. say if get 2 long lights and 3 quick flashes . that equals code 23. refer to a code listing ,, i think 1300cc.com has them . and that should help.. it did for me when i was having problems. as for the snap on scanner. you need the right connector. the kit comes with like 20 over them . then you need the right card with a troubleshooting card that corresponds with the scan card. <-- sounds confusing .. but if you have it infront of you you will under stand. i believe there is a adapter that comes with the kit that has spade terminals .. i believe thats the harness you want to use. but im not 100 percent sure. i used the jumper technique. good luck

 

You probably have a OBD scanner.
NO FC is OBD complaint, so it's useless.

Obd?

 

onboard diagnostics

 

on board diognostics

If it is the tool im thing of it wount tell you any thing unless you have a check engine light on.

 

i thought RX7s were OBD1?? damn. i was going to have my friend at Lincoln Tech use an OBD tester on my car just to see what it would tell him. guess i'll call off the search party.

 

obd was started in 92 or something right??

 

No, NO RX-7 (even the FD) were OBD1 or OBD2 compliant.
This is one of the reason why Mazda killed the FD in 1995.
Mazda didn't want to slap no OBD crap on the cars.

OBDII started in 96, and yes it is what killed the rotary until now and who knows how long the renesis will last since it is still fairly new and hasn't gotten a proven Cali smog track record yet.

back to the point, yes, if it is what we all are thinking, an OBDII connector, it won't work on any RX7, only an RX8. your best bet is jumper the check connector and do the "down and dirty" diagnostics, it is more relaible anyhow.

 

i dont think anyone was thinking OBD2. i knew it wasnt a requirement until 96 (some cars started early), but i wouldnt say it killed the rotary. i dont recall the production numbers, but i believe the sales numbers were in the 5000s for 95. sales dropped and i believe they had a lot of trouble with warranties, though i could be mistaken on that.
i remember hearing the renesis nearly ran clean enough to be an LEV vehicle. i dont know what came of that, though. different cars require different emissions numbers and i dont know where the renesis falls nor what emissions it puts out from the factory. i'm curious to see the numbers if someone has them.

 

a brand new renesis may run clean but so did most rotaries off the showroom, put a few miles on them and you can choke on the tailpipe, even with the emissions system in perfect working order most rotaries need a little nudge to pass california emissions, remember they put 4 cats on the FCs, that should be a hint at something.

 

Yes, dropping sales figures was probably the primary reason Mazda dropped the FD in the US, but the OBD requirement was another factor that lead to the ultimate cancelling of the RX-7.

The FD was a very strong seller in Japan back in those days, and I'm sure Mazda would've kept it alive in the US even with dropping sales.
The Chuuki FD3S (1994-1998) was a step up in reliability, and the Kouki FD3S (1999-2001) pushed power output up to 280ps.
FD3S sales even outsold the vaunted Nissan Skyline GT-R R34 in matching years!

280 Ps Rated... isn't that the maximum for all Japanese cars? Who knows what it actually was pumping out....

 

The renesis doesn't have the overlap from periphereal exhaust ports... I highly doubt there is anyway for a periphereal exhaust ported rotary to pass today's current standard emissions even when brand new.... there's just too much overlap.

 

speaking of which, as i asked earlier, what numbers do the RX8s put out and what is their max standard numbers (county by county may differ, but i'm curious as to whatthe numbers are). i have a copy of HAILERS numbers as he posted on teamfc3s; it ran unbelievably clean. i would be willing to put money that it would pass the RX8's requirements.

 

SO... back to the subject...

 

everyone agrees? not able to use a diagnostic scanner on the rx?

 

^ Yes Already!!!

 

Did we all speak in Spanich or something?

oh Reallllyy!

Thats an interesting tidbit of info...

 

Here is your answer in case you did not understand the above responses: http://www.obdii.com/connector.html

http://www.obdii.com/obdii.html

So that answers that. Now just make yourself a breakout box for the ECU and do your own diognostics using your digital meter. Don't need no stinking scanner (although I do have one for my 98 vehicle, and it woks just peachy keen fine).

 

btw .. if you watch the thing about CT emissions. they proved that alot of emission stations are corrupt or not doing their jobs when they passed a i believe it was a lamborgini or a ferrari with a OBD2 scan test for emissions. what they didnt tell the station and what alot of people know now is that alot of the italian car makers dont want to conform to the obd2 platform. they put the connector in the car. but they dont hook up the ground and they dont run power to the harness. but when people found out that the cars ( forgot which one , i think ferrari) passed with flying colors they new that the emissions testing was mostly faulty and not very accurate

 

Yeah I just got a little confused with ALL the jacking...
