4 Pin connector for OBD2 device

[CamboForza]

Hi,

Can anyone tell me if they have used the 4 pin to 16 pin cables and hooked up an OBD2 device??

I know there is a DTC Diagnostic Trouble Code connector but unsure if an OBD2 will work on it.

Also, it is supposed to be near the battery but I think it is elsewhere, anyone know??

I don't really have any issues, I just want to hook it up and have a look.

The diagnostic plug is behind the right hand glove box. You have to remove two screws at the top of the glove box (you will see them when you open the glove box) and then remove the top cover where you will see the fuses and the diagnostic plug.

Cheers, I thought it must be that one. I'll see what happens when I book it up.

Let us know how it goes.

Any idea if you can fiddle with the fuel mapping from the OBD2 Port ? or do you have to hook directly into the ECU ?

Cheers, I thought it must be that one. I'll see what happens when I book it up.

Be prepared to buy an ECU if you start remapping it without being an expert.

It is not impossible to do but probably not worth the risk for a slight if any improvement. BTDT.

Make a copy if you can, in case the engine doesn't work properly after you changed things you can reinstall the correct mapping

I'm only using it to see what data I can get out of it not to remap anything. I think you'd need something different to do that. It's still in the post at this time. I'm going to be able to log data as I drive, mainly air fuel ratio if possible.

They sell the software for remapping of Forza ECU here including cables with connector for a special offer of ~US$55 here in Thailand...

I like to remap mine but don't dare do it myself, the recommendation is to buy another ECU, new or used, then play with that, any issue, can just plug back in the original...

They say both Honda old and new models are highly tuned to get better fuel consumption, and be Euro3/4 emission compliant, throw all that out of the window and can get some more rpm and power out of it...

Have you got any more info or links.

I was able to plug in the OBD2 device and connect to my phone. I haven't been able to get it to connect to the ECU yet, I did start to go thru all the protocols, but then it started raining so I stopped. I gave it probably a good 20 minutes though.

I somehow think it's not possible with a standard OBD2 device.
