Ive heard this now from a few people that the scion tC is actually OBD3 and not OBD2. Scion, Trd, And dealerships show it as OBD2. Im wondering witch is true from what I hear OBD3 will not learn like OBD2 and this is why you can run a emange with no problems. I don't know how true this is but im trying to find out. Anyone shed some light on this?

 

No such thing as OBD3 yet, but here is a link that discusses what it might do...

All OBDIII is CAN (Computer Area Networking)

 

I thought that was refered to as OBDII CAN, not OBDIII

 

So did I but I learned last night in class that OBDIII is referred to CAN.

I believe the C6 Vette has CAN w/ their sensors on the tire valves.

 

As has been said already. and to the best of my knowledge OBD3 is not yet released. I know there are no OBD3 automotive scanners out yet. The ecu's in the 06 and 07 model vehicles are the most advanced and adaptive ecu's ever produced and have been noted as being only a few steps below the rumored AI. They have some of the most adaptive programs and react with speeds that were only dreamed of even 10 years ago.

The ecu has the ability to learn around some aspects of the emanage and it has been an issue for MANY people running it with forced induction and has been well documented on the forums. I could personally watch my air fuel ratio's begin to fluctuate on the highway after a few thousand miles of driving and I reset my ecu with every oil change to resolve the problems. I believe I had read numerous times where ZPI says that you have to let your ecu "learn" that there is a turbo there before your car will act properly when you install their kit.

I know when I had some issues with my emanage ultimate when I first installed it, I actually unplugged it completely and drove my car on the stock ecu with the 550's in it and by the time I got to the shop it had adapted to the best of its perimeters and was running a 13.5:1 afr on the expressway. I believe when I got on it was in the high tens. There is NO DOUBT that the ecu has adaptive technologies.

However I would be interested in knowing how certian people "just know" that obd3 is what the scions are even though the scion reps, toyota master techs, trd reps, ect all say that its an obd2 platform. Some people would rather just say what they know is true then to admit they might be wrong.

 

The c6 vettes do have a version of the CAN setup but it is incorperated into the obd2 platform. True obd3 is rumored to have built in tracking systems as well.

 

Our cars are not OBD III. If you check under your hood it says "OBD II Certified".

 

I know I was 99.9% sure of it I just can't believe this place told me that

 

If anyones seen the BMW comercial where the service rep calls the guy in his car to schedule an appointment for service while hes singing kiddie songs. Thats OBD III! OBD III will be able to save people the hassle and expense of a smog check by sending a message to the government that the car is legal since the car does a smog check every couple seconds. OBD III can do other things such as wireless communication in the service bays and so on.

I dnt know if this is the kind of info you guys were looking for but i just thought id share some knowledge.

 

And people made fun of me when I start fashioning my Tin Foil Hat...

 

 

The 06 xB and tC have greater than OBDII technology. This may not be reconized yet as OBDIII as there are talks that OBDIII will not officially be out until a 07-08 model years with potential uplink abitlities the Scion and other new toyotas are essentially ready for this technology.

The term OBDIII may not be correct but superior than OBDII is...

 

Thats fine, but why the HELL would obd3 not have adaptive technologies?

 

who said they did not?

 

You did, do I need to post the conversation to remind you?

 

OBDIII would have adaptive technologies

 

Yes sir, and thats exactly my point. I see no reason for them to "dumb" it down from obd3.

 

ah my apologies sir. i read your post wrong, didnt read further down

 

Its all good.
