  1. Not to get off on a tangent, but if break a connector and can't find it anywhere you can sometimes find

    something that will work if you search around on digikey or mouser or somewhere similar.

    I looked for the connectors for the cluster in case I completely broke one but the part number is only available

    over seas and in bulk. $50 min order was the best I could find.

    I found something which would probably be compatible at digikey. Although you'd have use some tape or something to snug it up.

    Molex Connector

    There are links to crimp sockets if you break one off. Couple dollars for roll of a hundred.

    Or if you're a real cheapskate notice the "request sample" link. ;)


  2. I've been looking at some circuits, and I'm pretty confident that the spoiler can be made to be

    completely adjustable, and have a LED.

    And I think I can do it without soldering anything, or even cutting any wires on the car.

    It would probably cost around the same as the LED kit and a dash switch.

    But it'll be a little while before I can get started on it. I've got projects lined up for a mile.


  3. This problem started about a week after I had my spark plugs and oil changed back in July. I didn't think it was related at the time, but going back over my receipt I saw that after "Spark plugs" they mention "Slight tuning." I'm wondering if this isn't completely computer related due to Firestone's attempt at "Slight tuning" and if I should go have a Porsche specialty shop re-tune it.

    Well there's your problem. :rolleyes:

    I'm not sure how the IACV is set up because I don't have one.

    Some cars use a 3 position soleniod. So there's your 3 idle speeds.

    Sometimes one or all of the adjustemnts are on the throttle body.

    So changing the valve won't change the adjustments.

    If the mechanic "slightly tuned" (sheesh sounds like took the screw out and

    threw it away) one to 2000rpm he wouldn't have known because didn't drive

    it enough.

    That's my last guess. If that ain't it, give it up and go to the dealership. :lol:


  4. I thought a 99 was 37 and 75 mph.

    I've always been told the speeds were not programmable. Maybe they are?

    Would you happen to know the part # on the cluster?

    You might also ask the indy what tool he used and what version it was.

    I've been thinking of hacking the spoiler speeds for a while.

    My first thought was to use the 'speed gong' speaker output to trigger a relay.

    I went so far as to completely disassemble the cluster down to the board to find the speaker.

    There's what looks like a little speaker clipped to the board and it has 2 leads.

    I was about to cut it off but in a fit of temporary sanity I checked the MSRP on a new cluster. OUCH!

    Adding to that, I'm not positive that's where the tones come from. It could be something else. (Temp sensor?)

    So I chickened out, and decided to find a more elegant solution.

    I looked around for circuits that could use the speed signal. I THINK that radio control hobby servos use a similar signal.

    I haven't had a chance to get a meter on these signals yet.

    I stumbled onto a very very interesting site.

    AutoSpeed

    NOTE: The good news is prices are AUD so they're not as expensive as they look. Bad news, shipping from AU was $18 for my order.

    It should be here any month now.

    I ordered the voltage switch and frequency switch kits to experiment with.

    They also sell a book that I think has diagrams for most of these circuits.

    I bought the kits for the convenience of the printed boards, but I will probably end up buying the book as well.

    These circuits could be used to control just about anything on the car based on speed, RPM, pressure, temp, etc.

    A few project I'm considering;

    Adjustable spoiler speeds.

    One touch convertible switch. Switch disabled above X speed.

    Adjustable rev limiter.

    Adjustable redline indicator light.

    Adjustable flux capacitor speeds. :)

    Adjustable PSE activation speeds.

    You get the Idea.

    I have a lot of things going on right now so it will probably be a month or so before I get to any of this, but

    if I come across anything interesting I"ll post it here in the DIY forum


  5. A LED may operate down below a volt.

    Usually ppl comment that the flashing gets slower as the battery dies.

    I'm just saying I would try to find a known working battery.

    Maybe try holding the key right up next to the A-pillar.

    I've never heard of the continuous flashing, perhaps a button is stuck. Sounds like it may have bit the dust.

    There's allot of voodoo written about keys. There are some instructions on 'resynchronizing' your key

    by putting it in the door and pressing the lock/unlock button or something like that. I've never had to try

    it but apparently it works for some people.


  6. You can use a cig lighter if you're carefully.

    I usually just lightly brush the soldering iron against it.

    IMHO the shiny vinyl kind from radio shack sucks.

    It doesn't seem to shrink as well.

    Try to find the kind rubbery kind with a flat finish. You can get it at a hobby shop that sells RC cars and planes.

    It shrinks up better.

    But remember it's only gonna shrink maybe 50% so get the right size.

    Definitely best to solder.
