Hey folks.. Made a discovery when doing some research..

http://www.ozenelektronik.com/upload...ecusim1000.pdf

I am ordering one of these and will test it at an OBD-II inspection station, it doesn't appear to have non-continuous and continuous test modes, but I wonder if it will "Pass" on an inspection station's scanner..

This find **COULD** open up the standalone ECU market to people in states where OBD-II is required..

I want to contact the company to see if they can make one with configurable OBD-II output.. digimoto is a US reseller for their mOByDic product and if this thing can be custom configured, and/or works out of the box.. It could really make our lives easier!!!

this is the only product I've come across, its typically used for people testing OBD-II interface devices.. but seems to also fits a specific need for many of us.

 

although i'm not going with a standalone, i think if it passes inspection, that'll be a great thing for ppl in NY.

Great find man!

 

let us know how it works, this could be a big help for all of the sportcompact community! i will be checking back on this thread, let us know

 

I am trying one of these out..the company guarantees these or your money back..

This is not an O2 simulator.. This is an OBD-II simulator (and I need to find out if it supports the continuous and non-continuous test results as being "ready")

An O2 simulator tricks the stock ECU not to throw a trouble code, however there are some cars that will get other trouble codes due to modifications outside of the range the ECU considers normal (EGR valve or stock MAP sensor disconnected for some reason) which wouldn't otherwise degrade the car's performance or ability to pass a smog test.

Another problem is there are many people who are, or would like to, run a standalone ECU in place of the stock. The ONE thing that has held me back from running a full standalone was the ability to pass an OBD-II diagnostic inspection in NY State. I'm not trying to do something Immoral since my car passes an inspection on the stock ECU, but I would like to run a standalone ECU and further modify the car where it would be fairly impractical (though not impossible) to put a stock ECU back into the car and sucessfully operate the car through a complete drive cycle and not throw DTC codes or continuous and non-continuous tests.

A tool capable of responding appropriately (preferrably using a legitimate input signal from the sensors and ecu, but not essential, just the morally correct thing to do) when an OBD-II scanner used by an inspection station is connected.

I am purchasing a unit so I can write software for my Elmscan device, but I'm hoping that it can pass an inspection station's diagnostic connector.

There are several issues that I can see preventing this from working right..

real time sensor data may not provide the right/adequate info to satisfy the inspection device
Continuous and non-continuous test results are incomplete or not supported
the inspection computer diagnostic device is expecting specific model information from the car, and OBD mode supported, and possibly vin# (since vin# does appear in many ECU's) etc...

BUt for the 98EU (About $100 dollars) its worth it to me to get the unit anyway.. If it works, then I can start evaluating standalone ECU's and start tuning my car with a standalone and still pass a NY State inspection.

I would much prefer to get an OBD Exemption and go through a sniffer test and safety/visual check (again, my car does pass these tests) but I don't know how to go about getting an exemption.

 

this device will not allow you to pass an emissions test. it simply emulates certain pieces of obd2 functionality for the purpose of developing and testing logging equipment.

I think something like this would be a good foundation for an emulator. I was looking into developing some sort of obd2 emulator for the purposes of emissions testing, the problem with a device like that is selling it. I can't think of a legit use for it. On top of the violating emissions statutes they might be able to get ya on DMCA violations as well tho.

Still be fun to try and make at least one tho!

 

Would be sweet if it would emulate OBD-II!

It would make my final decision to go stand alone if one was in development...

 

Its only current function is for testing OBD-II scan tools and writing applications for them.

A true emulator does have a legitimate use, in training mechanics for troubleshooting systems problems with OBD-II.. But we'll have to see what pans out.. My intention isn't to break the law, just that there are some who feel they must run a standalone ECU, and I was hoping to find something that could interface with the standalone and pass the appropriate information to the OBD-II emulation, but had no luck finding it.

 

right on!
(that is an expression from a long time ago. how embarrassing)

 

Malibu-
I was going to build one with the factory computer-

 

well, adding a standalone is breaking the law, so regardless you are breaking the law. I've lucked out and found out the zip code I am moving too in February is emissions exempt, so finding a viable solution has a lower priority now. But it still would be an interesting device to develop.

 

Hmm. This is an interesting idea -- piggyback the stock ECU off the standalone. In other words splice only the sensor inputs and leave the control leads unconnected. That way you actually get reall OBD-II functionality, but the stock ECU isn't running the engine. I wonder if that would work...

Yah unfortunately I know.. Not sure what to do about this stuff, its unfortunate that there are some of us who want performance, and want to do one-off stuff, and are interested in being green/clean.. Yet we don't have any flexibility in the tools due to the interference of the government. There are exemptions that can be applied for only their so difficult to get that it makes this kind of work prohibitive. The only way around it for me in NY is to have a "Home built" vehicle...

 

Technically you're describing what the UTEC already does its just that for as much as I love the UTEC, their really slow on updates I **REALLY** need.. But you do need to let the ECU have some control or it will never pass any of its non-continuous drive cycle tests.. Connecting only the sensors would result in a bunch of coil and injector errors.. I know, I tried..

 

i was going to wire in resistors, and put voltage regulators in line with a harness. Put a cigarette lighter plug on the power ends and wholla!!! A complete stand alone obd II passing device!!
