Afternoon all :D

 

Well it's happened, Eliza has become extremely ill! And I mean EXTREMELY!!!

 

I was driving down to Leicester on Friday evening, no problems all the way, until I got onto the M1, then I got a few 'coughs' and 'splutters'! Got off at junction 21a and pulled upto the traffic lights and Eliza died! Took a lot of starting again, then once it was started she was running very rough indeed.

To cut a long story short, after a lot of dieing on me and restarting, I was eventually able to get to Karen's house.

I suspected that the MAF and APEXi might have got wet somehow in the rain, so took them off and dried them out over night (the filter was a little damp) Replaced them in the morning, and took her for a test drive (as she started OK) round the village once and she started to die on me again!

Anyway Eliza is now back home (after another trip on the back of a lorry! :( )

I thought I'd attach my DataScan to Eliza and see if I could come up with anything! But no! Not in the sense of not finding anything out, but the CRAP software wouldn't connect to the ECU (again!) In the six months or so I've own DataScan I've had it connect to my ECU twice so far! This has got to be the worst waste of money I've ever spent on her! ConZult may be expensive, but at least it bloody worked EVERY TIME I wanted it to, DataScan is just CRAP!

 

So, can anyone help with suggesting where to look for the rough running/dieing?

And can anyone suggest what to do with the DataScan, to get it to bloody work?

 

TIA

Dave from what you said it was like what we had a few years ago in Wheelmans (Marcus'S) zed when the rain hit Castle coombe, took a few days to dry out properly.

but poss that the maf is now Damaged as there ment to be abit delicate

hth's graeme

it might not be this but these are the same simptons i got when i had water in the fuel

Hi Dave - I'm not able to give you advice as I don't have the knowledge, but I'm just posting to wish the very best of luck in sorting out Eliza's problem.

 

You have helped so many people out on this site, especially me, that I'm sure someone will come to your rescue and identify the problem.

 

Best of luck - Dave

does datascan give you an error? I had to change the port settings it was using on both datascan and conzult so they were the same. I've lent my laptop to a friend so i cant check what settings i have. I dont have any issues connecting either peice of software to the cars ECU, always works first time everytime.

Thanks to everyone so far....

 

The filter was only slightly damp.

PTU is a series two, which has been relocated to under the headlamp centre panel, and has had the old series one connectore removed, and hard wired to the series two connectors. All of the Coil Pack connectors have been replaced along with the injector ones as well.

Engine oil - OK. Gear box oil - OK. Water - OK. Water temp - OK. Oil Pressure - OK. Turbo boost - OK (when it does run at a decent RPM)

 

As for DataScan - It has worked with the settings and connections that are present, so I don't see why it just wont connect (it's NOT set to Auto Connect)

When the car re started each time, was there any popping from the exhaust ? not on the morning start up though, all the others.

Did you take the filter off the MAF to dry them out ? what sort of filter is it ?

Yes there seemed to be a little popping from the exhaust.

Yep, separated the filter from the MAF. It's a standard APEXi filter (bought from Danny)

I would of suggested PTU...but since you have a S2 then extremely doubtfull.

 

Unfortunatly water can permantly damage a MAF. Perform an ECu test using the old fashioned method to check for errors.

 

Sounds like using USB version of Datascan, if its been unplugged and you you've had other uSB deviced plugged in then the Port number will be different when you plug it in next and you have to enter correct port number in datascan. This does not affect serial version.

My DataScan is a serial version! David, can you remind me what is the correct procedure for stating DataScan up? Do you start the engine first and then plug the lappy in, or does everything have to be plugged in first, or what? Just so that I'm not doing it the wrong way round (although I'm pretty sure I've done it all ways round)

Meanwhile, I've just taken Eliza for a blast, or four, round my local supermarket car park :D and she seems OK :confused: I did a series of short and long blasts, along with more sedate driving, also kept stopping every so often to see how she was idling, and all seems fine, so I took her into town to fill up with petrol. Started her back up and she's running OK :confused:

 

Looks like I may need to investigate further still yet though!

 

Thanks again for all the help.

Have you tried running with the MAF unplugged? it will run as normal but the revs will be very restricted. Worth while if you havn't got another MAF to try in the meantime.

With the car popping it sounds more like intermittant temp sender problem.

As your driving the engine vibration is breaking the connection between the sender and the plug, this will cause overfuelling to the extent the car won't run, then when the car is stationary after a few pops of fuel being burnt off, she'll start gain and seem fine for a wee while.

It's worth checking by removing the sender plug, does it still hav ethe wire clip secured okay ? is there any water sitting inside ontop of the actual sender ? this causes intermittant readings. Another likely one for not as much, is the CAS connector, is the clip still secured okay, this will also cause car to die with vibration and restart when stationary and again gives of the odd pop as it dies.

Personally i don't think it's owt to do with the MAF or filter as neither would actaully cause the car to die, just run crap, however next time you do remove these, actaully clean the hot wire, this sends pulsed signals to the ECU, you can with no ill effect remove the wire gauze on the TOP side of MAF and wipe clean the hot wire inside with a clean cloth sprayed in brake cleaner or similar.

Oh and i couldn't be arsed with the datascan if it won't work, just do a simple ECU diagnostics or better still visit someone with a conzult to see the history of error codes.

Royal, Smithy..... :bow: :bow: :bow: Thanks guys, I'll see what I can come up with tomorrow evening after work.

There is no required set startup process. It should work anyway, do you have local Zed owners you can test your Datascan on ? .....just to rule out possible Consult plug problems

 

What happens when you click the connect button ?

I'll see what I can do on that one.

Nothing! It just sits there and nothing happens. I've tried the Find ECU proceedure as well and it'll go all the way through and won't find anything.

Like I say, I've had it working, in fact last time it worked fine. This time I've plugged it in and nothing.
