To all Pros sifus

do you all know about OBD 2 onBoard Diagnostic car-computer ScanTools programming ?

if yes, please share your experience and tools at here

thanks you .

I just ordered mine on Sunday.. I already have the software on my notebook, just need the bloody OBD2 USB connector..

Nobody seems to carry the product that I need, had to order it online. I'm looking forward to more diagnostics and uploading of ECU maps.

Date Ordered: Sunday 06 July, 2008

Products
------------------------------------------------------
1 x OpenPort for Subaru WRX and Drive-by-wire vehicles (Subaru WRX a) = $91.00
------------------------------------------------------
Sub-Total: $91.00
United States Postal Service (1 x 0.65lbs) (Express Mail International (EMS) (6 Days)): $29.75

maybe u can DIY cable OBD2 to rs232..

sleepwalker, what are its features??.... care to share??...

Mine doesn't require RS232 convertor. It runs directly on USB.

On the Subaru, practically everything as the new ECU can be reflashed, provided I get the correct mappings. It will also provide me with real time diagnostics, as in driving around with it plugged into my notebook, allowing me to monitor everything from injector duty cycle to ignition timing, intake air temp and of course to diagnose any issues that crop up via the check engine light.

means it acts as a monitoring device only??... cannot reprogram ur oem ecu??.... plug n play into any car ecu??...

Umm.. which part of the 'reflash ECU' that you don't quite understand? Subaru V7 ECU onwards are fully reprogrammable and there are free software online to do this. However, this can be risky unless a tried and tested map is used. Any car with ODBII connectors can be done and we don't plug straight into the ECU. My ODBII connector is under my steering column and I just plug it in there. I can even back up the ECU first in case something goes wrong.

Most car's ECU is not reprogrammable, not via the ODBII connector as they used it mainly for diagnostic.

means most current moderm ecus are reprogrammable??... or depends on car manufacturer??...

as like u said, means this device can as well act as a piggyback ecu??...

can clamp ur new fuel mapping/ignition timing from notebook?. cool stuffs man

Totally depends on car manafacturer. Most will lock out with passwords, but if the tuning scene is really active for that model like his rex you'll be sure to find it on the net somewhere. For every other car in malaysia, forget it, nobody will have a new ECU mapping, nobody will be a guinea pig to test it out and the gains are so minimal in the end.

No, you use it to reprogram the ECU, not use it as a piggyback. It can be plugged in and driven around to provide real time diagnostics and also to record the diagnostic readings for later analysis.

catacombs...
like ppl owiz do during nf7s rev2 punya mobo... re'flash' to tictac's bios.. to gain sum features... totally erased original bios....

dun understand...

buy subaru then u will understand. haha............

means they erase old AF mapping from ECU memory and load a new AF mapping.

OBD II is an old std
now its OBD IV

WHy OBD came about ?

Because CARB requires it.

The core function of OBD is to provide diganostics when its run with some external equipment like dyno and Gas analyzer todiagnose particular engine or transmission problems.

Been there - done that

i wish to ask you

as PROTONcars are OBD1 or OBD2 ? can i use the same connector as yours

thanks you

yup.....

u're right....

no need AFC to retune to make correction

Proton cars use MUT-1 and MUT-II connectors for diagnostic.

I don't know which standard you are following but ODB II is the current standard. There is no OBD 4 unless both you and I are not talking about the same thing. Furthermore, your explaination for the core function of the ODB is wrong. It was meant to be used on-board (aka in the car) and not connecting it to external equipment. That's the reason to have ODB so that everything can be done inside the vehicle and in real time, without the need of any external equipment. ODB also provides diagnostics without the need of any external equipment. Just plug in either a notebook or an ODB-II scanner to get the results, while the car is being driven around (if real time diagnostics is required).

CARB? for a moment there I thought you were talking about Carburator but you were referring to California Air Resources Board? I'm not sure now if you have actually been there done that since you are quoting abbv that is not commonly used in here. CARB? Dang.. I really thought you were talking about carburator...

to Sleepwalker

wow, seems you are VERy Professional on vehicle things

i wish to ask more about OBD and MUT Things to you

i wish that you could provide me some of your very Precious informations

thanks YOU>>

LOL!

try looking for scangauge II tools. PNP to to OBDII connector. can receive many info from ECU. can reset ecu check engine light. gonna get this if got extra cash.

anyone got lubang for this?

You'd have to order online. Mine arrived from Tactrix last Saturday and only had time to test it a couple of rounds. Plug it into my notebook and ran romraider to check. Shows almost 90 different readings, including how the ECU is learning to my driving style. Haven't had the time to throughly check it all out yet. Will most probably try again this weekend.

To sleepwalker

how about mine those lowyah wiras?

which Diagnostic connector should i use on my wiras ?

U MENTION MUT1 AND 2, BUT I CANT FIND IT AT ANYWHERE, I ONLY FIND THOSE OBD2 WITH "CAN" APPLICABLE TOOLS. CAN I USE THAT ?

i am very glad for your precious info's..

thanks you..

MUT and OBD not interchangeable..the pin layout is different..its like trying to slot a serial port printer into a usb port..

I've been helping few fellow mitsu owner remapping their afr/timing during free time. Glad to see another experience user around...

But hey sleepwalker, why don't you wait till 31st July and get open port 2.0? Much cooler... you don't need your laptop next to you, just log directly to memory card.

For monitoring gauge using OBD2, you can try Greddy informeter or Blitz. Limited stuff you can see but it's better than analogue gauge build by manufacturer default.

to ryan

all my WIRA, socket layout was based on OBD2 socket

so my wira Define as which version ? OBDor MUT??

thanks u

I need real time diagnostics while I'm barrelling down the road up to 7000rpm and I needed it now. Had a slight issue where the ECU was going to safe mode after a few mods that I did. However, by the time I ordered the cable, the problem fixed itself.

sleepwalker

what do you mean of your diagnostic

i cant understand it

do you have your model ?

Log, log and log... keep logging. No problem will fix by itself, matter of time it will come up again.

you can get off the ebay....the price is affordable.

ordered one and see what it can do apart from erasing the check engine light and diagnose probs.

It does fix itself. I found out that I was running on some bad fuel that caused knocking on my engine. ECU detected it and ran in safe mode, cutting my boost by half. Problem fixed itself when I refueled my tank at another station. That is why I needed the diagnostics from ODBII for me to find out what's causing the ECU to go into safe mode.

I have no idea what you are talking about. Already told you, Protons use MUT II and not ODB II. New Protons with Siemens engine, I have no idea. Old Protons with Mitsu ecus are running on MUTII. So ODBII cannot work on your car. End of story.

sleepwalker,

ima looking for data logger and basic mapping function for my pug 407.

tq

got the link already

Not sure if they have it for a Pug 407 but here's the link.. https://www.tactrix.com/

Not all protons though - savvy's using OBD2 connector..

need to get serial to usb adapter since most laptop don't have a serial port.

Or get a USB ODB2 connector like that one I have. Why bother with serial port?

Mine doesn't come with a usb cable.. only OBD2 to serial...

I just found out there's a much cheaper cable being sold but without bundled software...am I making the right choice by not getting this one...there's so many kind of obd2 diagnostic softwares - are they free or need to pay for them.

Bad fuel would cause knock... your timing will retard. If knock is aggresive, you'll run in safe mode (in my world, I call it close loop), which is a second map and less aggresive. You won't extract power on this close loop cause it is meant to protect your engine. Log, log and log again... that's how your car tell you they are healthy or begin to get sick (or other mechanical part start failing). I doubt diagnostic from OBDII could tell you what's going on with your car... you can test part by part, but it won't point you to exact problem. Cause there's no load, hence problem won't surface when car is not running. All you could get from OBDII mostly is DTC...

Just my opinion though..

That's odd, in my world, close loop means ECU ignoring the O2 readings and only using the fuel map, throttle position and air sensor to calculate the amount of fuel on high throttle. Since optimisation is not required on high throttle, the O2 readings are not utilised. This also safeguards the engine in the event of an O2 sensor failure. This what I call close loop (and so does the rest of the automotive industry). This differs from safe mode or limp home mode.

My ECU has what is called an advance timing multiplier. The harder I drive the engine, the higher the multiplier, the more aggressive the ECU drives the engine. Of course, once it detects a problem, the multiplier goes down and so does the aggressiveness and all the way down to safe mode if necessary. As for my igition timing, it keeps changing depending on the knock sensor and knock timing adjustment as the ignition timing is fully controlled by the ECU.

You sure there is not much the ODBII can read? I drive full throttle and full load while the ODBII is connected. I'm not sure what you mean when there's no load or did you mean that you take the ODBII readings while the car is stationary? I can take my readings on full load as the notebook records all the readings while I'm driving. Anyway, here are the readings that I can get from my OBDII. You decide whether it is enough or not...

holy smokes...that's a lot of readings!!! hope ya car ain't running on microsoft LOL !!!

Awesome tool you got there. I would say I got about 40% function in your list I can log that cost only US$30.

eyeap, close loop would mean ignoring o2, used when cruising... bla bla.. but o2 still used to switch between open/close. Thanks for the different in ours ecu, I can see our ecu need to learn more! Conceptually, they are identical. Oh, the load is ecu load, variable taken directly from ecu ram instead of calc using battery/injector size/afr sensor. Do you have something like that? 2byte load?

Yes I do and that is safe mode. I actually have 2 safe modes. One is safe mode that limits boost to 0.5 bar instead of 1.0 but the engine is still in a relatively healthy condition, maybe things like bad fuel or bad plugs, or anything that is causing some knocking in the engine.

Then there is the limp home mode. Severe issues like cracked gaskets, or even broken speedo cable (ECU needs speed for calculation) that threatens the health of the engine, will make the ECU go into limp home mode. In this mode, the RPM is limited to 4500rpm. This is enough for you to limp the car home slowly, hence the name, limp home mode.

It's not the tool but rather the ECU that gives those readings. Even if I use the same tool and software, plugging it into another ECU may not enable all those readouts.

And I also need this tool and software to reset the ECU. The new drive by wire ECUs in the Subaru cannot be reset by just taking out the battery connectors.

sleepwalker, your reply was very INETERESTING, i like it very much

by the waym can you offer me your software that you are currently using ?

i was thinking, if using your software i could make my FC better, and smoother

do you mind post up at here about OBD Software you have been using ?

thanks you.

We don't have those safe modes in Mitsu world (not sure about evox yet), so far someone completed disassemble the rom and add enhanced features like flash cel when knock detected, 2 maps switching on the run, vallet mode and stuff like that... controlling boost via ecu have just finish tested. Of all the mod, the only safety build in ecu is just safe map retard your timing and put a lots of fuel to keep your engine going.

I won't usually log all while tuning (especially all crazy 91 functions you had ) since I got restriction of 130 sample per/sec to log. And yes different ecu won't give full readings, there's many specs out there. Each time of remap, can't run away from battery reset or run into idling issue. Stepper motor need to re-learn..

Otherwise, how's Yvonne from your club? Hope to meet up to share some knowledge some day

I'm using ecuexplorer and romraider.

Haven't seen her attend any gatherings/mamak since I started joining them 2 years ago.

her ? gal ah???

Those diagnostic tool, do we just simply plug it in to the connector while the engine is running or we need to shut down the engine first?

While it's running/idling

Yeah, thanks. Tried playing with the fault code reader with my car a moment ago. Nothing much to play around with a Wira 1.3Gli ecu

Your tool only read fault code? Can it datalog and store the date, then replay later?

The fault code reader that i'm using can read and clear fault codes, read various sensors input, enable/disable fuel injectors, purge control valve, fuel pump, that's all i can recall for now. Not sure about whether or not it can log the collected data. Haven't got the time to explore it in detail yet.

Oh, can i plug in the fault code reader and drive the car like normal?
