Citrojim's AX, Pixo, C3, Running and Cycling Tales

[Zelandeth]

Might just take you up on that Jim!

The old Telequipment D61A (with the obligatory touchy triggering) I've got has done just fine for most of the stuff I've needed a scope for before, but this sadly needs a precise readout of the duty cycle %age in more or less real time, so I need something with some math capabilities built in.

Had a chance to play around with a mate's Rigol DSO a couple of years back and had to admit to being floored by the stuff you could do with it, never mind by how user friendly the thing was. Definitely on the longer term shopping list...

An old fashioned dwell meter measures duty cycle, you need to apply a conversion factor to get the right number.

[Mandrake]

According to Mandrake you can disconnect the left hand unit, as this is the microphone.

My Ultrasonic sensor replacement/repair thread was written for the Series 2 Xanita.

I think I read somewhere that the transmitter and receiver sides are reversed on the Series 1 but I have never followed that up to see if that is the case - the ultrasonic sensors on my S1 V6 are also faulty, if I set the alarm then it will often have the warning light on the dash flashing when I come back to the car, however as the Siren doesn't work you would only notice flashing blinkers when it happened. My Lexia can't communicate with the alarm ECU so I can't confirm the cause although I don't think it has ever happened with the ultrasonic sensors disabled through pressing the bypass button.

Disconnecting either transducer will prevent the alarm triggering, however its possible that disconnection of the transmitter may be detected by the alarm ECU as fault, so disconnecting the microphone side may be preferable.

Zel, my Hameg should be fine for your needs.... Yours whenever you want it and for however long.

Simon, thanks. Mine is an S2. I shall go and study your guide later today. It'll save me having to remember to press the defeat button every time I lock up!

[Zelandeth]

Could do it with a dwell meter (the Crypton can do that), though being something I'm fiddling with in real-time having a actual number I don't have to convert in front of me is a lot easier, especially the first time around. Plus saves me wheeling the thing out just now - that will be easier once the garage is sorted out at least.

When you next likely to be about Jim? Will drop by when suits you to grab it. Really appreciate it.

Any afternoon this week after about 16:15 or any time on Friday Zel...

Jim, i've just found these in my boxes of crap in the spare room



If the connectors are the same for yours you can happily try them. My ultrasonics work but the sirens dead so they're of no use to me!

[CitroJim]

Thanks Stu

I'll have to pop the door cards off to check... I'm not sure now exactly what the connectors in mine look like now...

Luckily, in an S2 it's only a five minute job to slip off the door cards...

Due to the adverse weather I drove Gabriel to work today. She's a lot quieter now she has a back box fitted!! In fact she was a real joy to drive..

Next week she'll be going on a trip to Somerset. I'm actually looking forward to it...

I never found the S1 cards to be too difficult either. I've got some coloured mirrors to fit but I daren't disturb the clips that I managed to save last time the cards were off

I always find mine sounds horrid but drives beautifully. The clatter of an IDI diesel is fairly alien to most people nowadays. Infact when the cold idle was screwed a colleague thought the car was going to blow up it was rattling that bad when cold at least it's sorted now.

They always benefit from a little tweak to the fuelling and boost, mines got plenty of get up and go once it's past 2k, up to then it just makes loads of noise and it seems to cruise brilliantly. I still get decent enough mileage to a tank if i've been, erm, tanking it infact I think only a HDI will cruise as well, and definately in a larger car where you can properly waft

[CitroJim]

That's very true Stu, it's a proper old diesel and I have to be honest it's a sound that I find really quite agreeable

Yes, it certainly has a nice bit of waft about it and I can tell you from experience that neither an HDi nor a 2.1TD are any better in the waft stakes... The HDi is perhaps a little quieter and a little more refined but that's about it...

It's also quite surprised me at just how comfy it is and how well a non-Hydractive Xantia on good spheres rides...

Coming back to a 1.9TD after all these years is a pleasant surprise at just how good they are and how well they still stand up to the competition...

I'm really rather happy

[chinkostu]

I'm glad jim! I can honestly say mines the best car i've ever bought, even with the matrix dying on it.

Has Zel fitted new spheres recently? If I were nearby i'd compare it to mine as I can't decide wether mine could do with a replace/regass on the front as it gets a bit jittery now and then :-/ although it soon tells when I take the wifes fiesta out and shake to bits!!!

Yes, and not long ago.. I helped him swap the rears...

I know what you mean about the Fiesta... Yesterday when my 1.9TD was in for its MoT and new exhaust I took my C1 to the shops... 'Nuff said!

With a Xantia you tend to get very sensitive to every little change in the perceived comfort and ride after a time and it takes a drive of a conventionally sprung car to bring it home again just how good the Xantia is and to reset your expectations....

[Zelandeth]

All new corner spheres were fitted back at the end of May if memory serves. Jim will be able to confirm the exact date as it will be noted on the slam panel.

Have made myself up a conversion chart to do dwell-duty cycle conversion - according to my brain it should be:

Dwell angle in degrees/(360/number of cylinders)*100 = duty cycle in %.

Reckon borrowing the scope would still be handy though to see what is going on in real-time as both my meters are quite sluggish. Also curious to have a look at how the lambda sensor is behaving as I'm becoming increasingly sure that is half my problem, and is switching levels as it should, but is being sluggish, and I think the whole system is effectively oscillating as a result.

[CitroJim]

A good stock of instrument bulbs have now arrived so either this evening, tomorrow or over the weekend I'll make Gabriel's instruments shine brightly again

[superloopy]

Write it up Jim ... mine have just gone off on the left hand side ... fuel gauge et al.
