I am located in the Rhondda South Wales. I will get the 58x, if it does not do the job I will make it available for sale / or to try, as I am grateful for the advice I have had from this forum. Cheers Rae.

I saw a picture of an Ecu on E bay with a thing that looked like a 58x on it and there were a few numbers on it.

Yep, you can see the label with CCF002 on there.

Ah yes, you have the EGI system.

I'm not 100% sure about that.

I have checked the wire colours and they are identical.

And code 12 stored in the LPG ECU for an EGI system is the crankshaft signal amplifier that has failed.

Well it may cost a few quid but at least I know what is wrong now :D I have electronic injectors on my car so I thought it was the gsi type. Thanks for all your help, I will now get one and report back :D :D :D. And the different CSA are not interchangable?

Nope, sorry, my mistake, I looked back at your previous posts to see which system you had and read your first reply which said EGI. I didn't read your correction a couple of posts later.

You do have the GSI if you have the electronic injectors.

The signal amp. in that picture should be fine so long as it's a worker.

Code 12 for you does mean ready to supply codes.

Right, got a ccf002 and the gas was working fine and I have done 200miles on it :) However this morning the car started missing in gas I have found that no1 cylinder is not working. I done the code and it is giving me the 12, followed by 3 and then 2 anybody know what that means?

Code 32 Official description. petrol injector off short to ground or open. This would normally appear if the vehicle has run out of LPG or the LPG ECU has seen a concern and it has changed it back to petrol. i.e incorrect fuelling.

Above is the official description for that fault.

I assume you have found that cylinder not to be working because you have read the petrol ECU. Have you confirmed by crimping that feed pipe to that injector.

Rather than me repeating myself, if you have a read of this recent thread it will point you in the right direction and you can ask any further questions you want here still.

Basically, just work on the misfire you have got.

Running on 4 on petrol but 3 on gas and I know which one because I took a look at the plugs. Also I put a noid on the petrol injector wire to see if it was knocking off on that cylinder when turning on to gas and that was ok. Wonder if I have run out of gas :oops: ?

Oh well filled with gas but still the same I think it is an injector sticking open. I am now looking at getting a set of ultra injectors for 40quid new and fitting them and be done with it. Rae.

You cannot just buy a set of injectors from anywhere.

The Koltec system will only work with the Koltec injectors. They have to be a specific impedance and speed and size injector hole. If you do happen to find some that work identically, you would have to re-drill the manifold because they will not fit on the Koltec spuds.

Read this post, maybe you can save the injector. As you will see, the injectors are very expensive.

Also, check the wiring to the injector, sometimes the insulation rubs through where the wire are tied up at the brackets.

Will check the rubbing. Anyway I fitted a romano type c injector to no,4 cylinder which I know is too big, but is all I had at the time and that is working Ok. I can get a set of brand new (anyone can) Ultra injectors for 40 quid. My intention is to remove the manifold, drill and refit with a set of these. Any thoughts on this are welcome, and I thank you for your help so far. I will of course update with my results for our mutual benefit. Cheers Rae.

It may be 'working' OK but, you need to consider the following.

Can the LPG ECU modify the injector timings enough to be able to run at the correct mixture?Adjusting the pressure may help if not.

Is the impedance the same? If the impedance is lower, too much current will be drawn and in time permanently damage the ECU/ emulator.

You would be very lucky to find anyone with winmonio software to assist in the setup if needed.

I have heard of an installer in Wales that replaces the injectors with another type but I don't think I ever found out what with. I know another installer that has been attempting to find a replacement but has found that although some will run at first, damage is caused to the ECU eventually. The last time I spoke to him he had not found a suitable replacement.

Following are the specifications for the Koltec injectors.

GSI Gas Injector Specifications
Recommended Inlet Pressure 80-200 kPa
Max Flow Rate (2.75mm)
LPG (196-204 kPa): 3 g/ s
CNG (100-200 kPa): 1.95 g/ s
Durability 500 million cycles
Minimum Injection Pulse 3 ms
Operating Temperatures -20°C to +125°C
Linearity +/ - 2% (above 5ms Ti)
Static Flow Deviation +/ - 2%
Opening Time 2.0 ms
Closing Time 1.5 ms
Inlet (top feed) 8 mm hose connection (E67R-01/ R110)
Outlet To customer specific requirements
Coil Resistance 19 Ohm +0.5/ -1
Driver Saturated

If you do go ahead with this, it is appreciated you are willing to keep us updated either way of the outcome.

OK That will help :D . I am going to try, as it is not going to break the bank, and if it does not work, well there we are. Will keep you informed :) Cheers Rae.
