sorry Joe I went to check if the scanguage worked on men showing AFR but, flat battery

[The Batman]

went out and had an error code p0170 which i guess is just due to the lambda 1 being turned off (to see if the afr would go up) afr went from 10.0 to 12.0 but then back down to 10.0 between pin a and b it fluctuates between 5 - 11dc V i have no idea what this means!

[Exmantaa]

That reading should be in mV, so maybe you got the heater wires?

Try and measure between A + ground or B + ground.
Will put a meter on my spare sensor.

Edit; C & D (black) definately heater wires as there's a ~28 Ohm resistance between those.

i cant until tomorrow now

[Exmantaa]

Then better look up the scangauge settings tonight. Or even better get your Opcom working, as that simply shows you all sensor read-outs.

[vocky]

pins 1+2 are the heater, 3+4 are the sensor on the vxT ecu

[The Batman]

It's a obd - USB cable... It says something about needed to install the driver but I can't find the disc not does it automatically install like normal...

What is the setting called that I am looking for?

[Exmantaa]

Ow yeah, i.i.r.c. Opcon needs a bit special manual driver set-up... @ Vocky; I assumed Joe still has the square 2.2 connector fitted to his O2-sensor and that is marked A-B-C-D

[The Batman]

I have the rectangular one as lambda 1. Does anyone have this driver info on the web do I can just download it rather than hunt down a disc?

[techieboy]

Joe, are you using an OP-COM cable/interface? Have you tried to install the OP-COM application from the VX Wiki page? That has the USB drivers with it and when Windows asks to look for them, you just need to tell it to look at the OP-COM drivers folder.

I know it works as I used it on Lee's car at the weekend. It'll definitely show the voltages for both lambda's and draw you a pretty wave graph.

[Exmantaa]

^^^ It works something like that with the OPCOM USB drivers. Will see if I can send you the software by mail as I have it on a stick somewhere.

[The Batman]

yeah i am using that programe (the one you posted in nickb777s thread the other day) hmm i will try and figure it out tomorrow car is pissing me off

[Exmantaa]

The car can't help it... It's just suffering from a severe identity crisis...

[techieboy]

It's definitely an OP-COM cable you've got? If it's just an ELM327 cable, you'll need to use some different software. You're using Windows 7 aren't you? I've just tried it on a Windows 7 machine and you need to manually install the driver for the interface as it doesn't look like the installer is compatible.

[The Batman]

Yeah windows 7 how do I do that? I dunno it was sold to me as a obd to laptop cable. For a link to one that works on eBay??

[smiley]

Complete shot in the dark here. You are one of few running a Phenolic Intake Spacer and a very efficient SC. Any chance of minor misallignment, as you had to adapt the inlet manifold bracket?

[The Batman]

You don't have to adapt the inlet manifold adaptor just space it out with the ones included. Presides wouldn't this just give an air leak and erratic idle?

[techieboy]

There's two kinds, one is an OP-COM interface which is specifically for GM cars and has a different pin connected in the plug, so it talks to ABS and airbag etc.

Then there's a generic ELM-327 interface, which will talk to pretty much all cars but in some cases doesn't talk to everything (like on our cars).

If you have an OP-COM then you want the OP-COM software to use it. If you have an ELM-327 interface, you can just use a generic OBD application like ScanTool or Engine Check.

If you're using OP-COM, it barfs on the configuration of the drivers but does install everything you need. When you plug the cable in, WIndows will tell you it's trying to install the drivers then fail after a while. You then need to go to your Start button and click on it then you need to right-click on My Computer. It'll bring up a new window with a link on the left hand side for Device Manager. Click on that link. Now if you scroll down the list in this window, there should be a device with an exclamation mark at the side of it called OP-COM USB v2 interface. Right click on that and click on update driver software. In the next window, click on Browse My Computer for Driver Software and point it at the C:\OP-COM\drivers directory and it should find the driver okay.

Obviously, all of the above is bollocks if you haven't got the OP-COM interface (although some of the manual driver install might apply).

My OP-COM interface looks like this:



My so called TECH-2 interface which I've never been able to reliably get working



And a crumby universal generic ELM-327 OBD interface

[Exmantaa]

Is it not that you need to manually install a driver "A" and a driver "B" for Opcom? Anyway, look for the exclamation mark(s) etc.
