    Default 505 Econoscope

    All,

    I know it's a stupid little thing, but I like things to work on my cars! I dont know if its blown globes or that vacume - electrical unit under the bonnet. Has anyone spent any time playing with this thing ? as neither my Haynes or factory 505 Manual mention the setup at all. Is there anyway I can bench test the vacume unit ?


    Any advise would be great!

    Thanks

    Ben

    Default econoscope

    The problem with these can be either or both. The vaccum control has a diaphragm which moves two sliding contacts, if the diaphragm has holes in it the scope will only show the red light. Common problem. The scope can also have blown globes. Regards Pete

    I am gunna get another 403 on the road........one day

    Yep, when I first bought my 505 it didn't work, it was always lit up on the red. As I at that stage I had no mechanics experience, I took it to a Pug mechanic to get it serviced. They found and fixed vacuum leaks, which caused the econoscope to start working, and the air vent position lever to start working too.

    I noticed the green globe for the econoscope didn't work so I pulled out the instrument cluster and replaced every single light globe back there. Made a huge difference to the lighting for the speedo etc too. All you do is take off the steering wheel, then get two little hooks into the holes in the sides of the instrument cluster and pull.

    Guys,

    For those that care its all fixed, the history was that it had been taken off the car in another life and the wiring tucked away and vacume point blocked off, I grabed the vacume solinoid off another wreck and plugged it it to no avail.

    Today I checked the globes......3 blown!

    All fixed

    Cheers

    Ben

    PS Funny that none of the manuals cover the topic!

    It's also possible to repair the diaphragm in the vacuum unit if it's full of holes. Get some Silastic or other silicon/rubber based sealant and smear it over the rubber diaphragm to cover the holes. When it cures, it seals the holes and remains flexible enough so the diaphragm is still free to move inside the unit, and bingo, working econoscope!

    It's how I fixed mine after I got the tip from Jason (Pug505Exec) some eons ago.

    Cheers,

    Lol, well anything more than gentle throttle pressure will tend to put them on red

    I aim to get green when cruising along, as it helps you work out how little accelerator you need to keep a constant speed. That said, at 100km/h or above it can be hard to get them off orange, as these cars don't hold a constant speed well with crosswinds, hills etc.

    As for accelerating from the lights, well I don't think I've EVER managed to keep it below red, then again I've been known to rev my poor pug to 7000rpm in the past so what would I know about fuel efficient driving?

    I'm actually a little surprised that it got there. I was only thinking today as I drove home in my 505 GTi that it's not an engine that really wants to rev. It runs nicely but it doesn't feel like it wants to go much past 3500rpm.

    Once you get past the fear that the engine's getting a little too noisy above 3500rpm, you'll discover a hidden abundance of power and acceleration in the narrow band between 4000 and 5500 rpm! (OK, maybe not an abundance, but there is some there...)

    This is the case with my engine setup (EFI) but I don't know that much about the carby engines. I imagine they'd behave in a similar way though.

    Mine's also EFI so it should be the same. I'll see how it goes but I don't feel like pushing it too hard (I've got other cars that'll do that).

    Yes, I have the Pushrod Carburettor 2L engine, which is far more 'rev-happy' than the ZDJL EFI engines you 'gti' guys are running .

    It is insane driving it that hard, but I still have an engine and it still runs sweetly. I'd never do it again, but it has certainly proved its durability .

    Hey Silverexec, the econoscope they are talking about here, I don't think I have it on my '88 GTi Wagon do I? I can't see anything in the owner's manual either. It must have only been on the GR.

    My GTi is an '85 model - a series 1 - so I do have the econoscope located at the bottom of the tacho.

    All series 1 cars came standard with an econoscope, don't know about the series 2 (from roughly 1986 onwards). I can't recall seeing an econoscope in these, maybe Peugeot realised how pointless it was by that stage...
