OBD2 on Honda PCX that works!

[vamootsman]

What does it do and what will it tell me? I’m not familiar with it all so pardon the newb questions.

The OBD2 is the interface with the R2D2 and C3PO accessories.

I use a similar program with a Navport cable to diagnose the Buell. Extremely helpful if you have any issues with electrical or just total peace of mind. I need that little gizmo please hook me up to where is best price in US if you know.

[WI_Hedgehog]

These are all over eBay and Amazon, it's not a huge secret. See if you can find them mentioned on other forums as working great, the best thing since sliced bread. (I haven't seen that...yet.)

So that's what the plug next to the battery is for! :-)

This is pretty legit! I've got a couple bluetooth scanners already, so for $20 or so I can find out my RPM for variator tuning without having to buy a "useless" tach that only serves one purpose.

Seems odd that there's no US seller with this "Honda 4 pin" to OBD2 adapter, tho....

Exactly the reason I bought one of these adapters of lonelec after reading this thread. I ordered them (from the link provided in this thread) and got it delivered a couple of days later. Now I am just waiting for the obd2 bluetooth transmitter. Once I have the obd2 bluetooth module I can finally see how these 13.5 dr pulley sliders affect rpm compared to the stock 15gr rollers. My butt tachometer is not calibrated but I have a strong feeling with slightly heavier dr pulley sliders it will run better - the rpm's will tell.

does anyone know what is the wiring diagram for this? I cant ship items here in my place. i will just DIY it. I have a obd2 bluetooth already... i need the 4 pin obd2 connector to 16pin. thank you !

[Ganglylamb]

I imagine there is a small microprocessor in the 4 to 16 pin connector, probably the signals are somehow serialized and/or multiplexed so unless you know exactly what order of bytes (i.e. low and high signals) etc. are coming out and how they should be translated into multiple channels it's a lost cause.
Seeing as a lot of data (rpms, MAP sensor, ...) should be available through these 2 pins (the other 2 will be for power I imagine) there is definitely more going on than simply a "wiring diagram" - unless you count the µprocessor as wiring as well . Takes me back to the time when we made a simple µprocessor in uni from basic logical units on a breadboard - too many wires to debug when something was wrong .

@MadSteamer: I hope you are still lurking around on this forum; anyhow here goes.

I finally got my obd2 adapter, got the torque app but nothing is being read. I can connect to the adapter using my smartphone bluetooth connection (paired successfully with the device).
Exactly what type of adapter do you use? I bought a cheap one off Ebay - it goes through all the connection protocols present in the torque app but nothing seems to work.
Additionally I downloaded some other apps which say they can communicate with obd2; I gave up trying when one of the apps shut down the bike's engine while it was running upon closing the app. Luckily no harm is done as it still runs ok as before; but let this be a heads up for other people; if you do not know exactly what the app is doing it could very well ruin your ecu I imagine (as you have no idea if it is writing some crazy things to the ecu).

I am tempted to buy another obd2 adapter - this time a more expensive one and hopefully a genuine one, but I would like some confirmation before I spend more money on this...

My experience is that even a cheap one works perfectly. Unless it’s a dud. Try it in another vehicle?

[iceman]

If it's an OBD connection then it should be to the OBD standard, so as you you states, may be a dud.

[raito]

Hi MadSteamer, could you please give me a link to your generic Bluetooth OBD reader, assuming you bought it online. I just got mine but it appears to be a dud.. I tried it on another vehicle other than my PCX and got the same result, so I don't think my 4-pin adapter by Kitaco is the problem.

[WhiteNoise]

raito, I was about to suggest that you try sending MadSteamer a private message. Then spotted that he only has 8 posts on our forums (members need 15 or better to pm).
Oh well. That option is out. Sorry

Please Come Back MadSteamer! Need Help!

I've got an OBDLink MX scanner and was unable to get it to work. I've got a few of the ELM 327 scanners somewhere, but I just can't seem to find any of them now. I know I gave the smaller blue one to my brother. But I should have another two or more somewhere.

I'll probly wait until I hear of someome else getting a specific one that works, tho. Been spending far too much money lately.

[grndslm]

Found my ELM327 adapter and even tried an HT200 adapter I picked up from Walmart that supposedly had "more PIDs" and/or protocols or something...

Still... *NO PROTOCOL* works with this Lonelec 4 pin adapter and my PCX.

I'm bummed, because this would've been so awesome. Wondering if the OP happens to be associated with Lonelec company and sold a few extra of these to a few suckers like myself. Hmm... :-(

[accyuklad]

I reckon this needs to be deleted if its fake

[chicaboo]

It's possible that the OBDII interface only works on the current generation of PCX?
I'm pretty sure we established years ago that it wouldn't work on the first gen 2013-.

[Rineymotorsports]

Hi there,
I thought that I share my latest discovery on connecting cheap Bluetooth OBD2 reader to the PCX. All you need is:
-cable from here
https://www.lonelec.co.uk/Honda-4pin-OBD2-Adaptor

-Generic Bluetooth OBD2 transmiter/reader
-Torque app
You plug the cable to PCX red service port next to the battery and that's it.
You can read all the data available without expensive gauges.

Thx!

What year PCX do you have I have a 2013 but I'm swapping the drivetrain on to a Ruckus I ordered one of those plugs a week or two ago and haven't seen it

[Conelite]

Doesn't work on 2017.

I bought the Kitaco Adapter and the ELM BT scanner. No data is transferred thru the Kitaco. my ELM scanner works flawlessly on my car.

I also tried another plug and play aRacer Display but no data. Waiting to hear back from aRacer for a firmware update to get it to work.
