Rovergauge soft ware

[LenChim]

So I have a problem with my Chim 4.5 2001 . When it gets hot it hunts, the tick over goes from 1500 to 0 rpm, sometimes it trips over itself and stops. I was told that the "Rover gauge" system would give me an in-site to what is happening with engine.
I have bought the rovergauge cable and I have been told that I can down load the software from the net. Now not being a computer nerd I type in "Rovergauge soteware" I get lots of info about codes etc but nothing that says "Down load software here"?
Can anybody give me a link and any instructions as to what is required?
Many thanks.

I have not been able to work on my car due to damaging my knee but I am now back. I have downloaded the software opened it up and plugged the computer into the car. Now I am to not cleaver with this sort of thing so of course I ran into a problem straight away. I assume what is the normal screen came up on the computer. Ignition on and engine running.


Pressed connect and got this message :- Error connecting to 14CUX no serial port specified. Set a serial device using " Opions-->" Edit settings.


So what do I do in :- "Put in serial device name"

The problem is there is nothing there when you press the drop down arrow on the box, I have tried typing in com1 and com2 but there is still no change.

Right you need to get into your operating system to define your com ports.
What OS are you using ?

This thread might help.

OK Back again, I have tried many things.Made sure all the connections are clean ECU and rov cable socket etc.
I am running windows 7 so the info on 10 did not help but gave me an insight.
The device manager gives me the following:-


So what do you think I should put in the Connect to box?

This is the Wire I bought:-


As I could not get a connection I wanted to check the continuity from plug to plug, these are the fingers I got are they ok or do you think the lead is duff?

I have tried 1 through 4 , the computer has 3 ports.

When I plug the cable in it makes a clunk but does not show up on the comp or try and populate the field in the software.
Has any one in west Sussex got a cable I can try? I am going to try the cable and computer on another TVR Chim later.
As you can see I have tried to make some seance of the cable connection with no luck. I contacted the supplier of the cable and this was his reply:-

Dear len

Hi there
plug the cable into the cars 5 pin plug
switch ignition on
plug into computers usb port
run software

what com port does the software use
options
edit settings
serial device name
NOT com1 that is the physical com port on the back of the computer, should be another com port if not the usb lead drivers have not been installed

The usb to serial connecter has an intergrated between the two plugs so you won't get any meaningful readings

connections 1,5 and A are the zero volts or chassis connections whatever you want to call them.

How are you getting good connections with the usb connector with your multimeter

It really did not help much.

You need to install the driver software for the FDTI chipset that the USB cable uses, or it wont appear in device manager.

I can not find software for a FDTI chip set but can for "Utilities - FTDI Chip"! Was FDTI a typo?
Thanks

Ok, I am back, I have now got the system working.
These are the Fault codes after a run when the engine got really hot! Fan on stuck in traffic, The revs ran up and down 2000 to 0 then bounced back up again. If I put my foot on the throttle I could stabilize the revs at a fast tick over 1100 rpm. When I got clear of the traffic the temp dropped,the car seemed to run ok but if I did a slow gear change the revs dropped right down past tick over possibly 200 revs.


I canceled all the fault codes to try again.
This is the engine running cold just started up.


This is the engine hot. Running fan. Still just ticking over.



This is what it came up with for fault codes. This was all static running in the garage.


So the implication is low fuel pressure?

Its likely both lambda probes have dropped to 0 volts for a period, so the ECU picks up a "lean" mixture that could be low fuel pressure, but a low lambda voltage can also be a bad misfire and the ECU cant tell the difference.

I have looked at the plugs again, they all seem to be about the same grey/fawn in color for the electrode and the tip but the outer ring of the plug has soft black soot as though it is running rich at low revs. I do have a misfire sometimes that you can drive through seem to be 2200 to 2400 rpm. I have not checked the fuel pressure yet I understand that is supposed to be 36psi but is that static or with the engine running at a number of revs?
