Tachometer question???????

Gumba11 · 02-16-2005, 10:21 PM

Hey all,

Im new to this forum but always on turbo911.com , Ive been spending a lot more time here in the last 2 days. (Shhhhh)

I like what ive seen here so far. Amazing forum, lots of info.

Here is my question. When you run an Autometer tachometer on a stock 930 ignition system is there any trick to it to make it work with capacitive discharge ignition, or is it the same as any ordinary setup?

Thanks for any help. Just trying to get an idea before I purchase my new tach tomorrow.

Hi Chris,

It may be that you haven't gotten any response to your question, because you already have a tachometer in your car, and why would anyone want to have two.

Most of us have found over the years that the Porsche (and Bosch) engineers REALLY knew what they were doing when then engineered these cars. Replace your bad tach (I'm guessing that's the REAL gist of your question) with a used Porsche tach, and it will give you lots of years of enjoyment.

First of all lets not question my IQ here. I am not putting TWO tachs in my car I am replacing the factory unit with an Autometer. I guess the multiple GT Porsches I have seen with Autometer tachs in the factory spot must be missing something here. Maybe we are all just stupid but Autometer is used the world wide by some of the finest race cars for the accuracy!

My question has already been handled by Autometer tech support. Thank you for help?

The real "gist" of my post was to let people know I was replaceing my tach with a BETTER one, not 2 tachs, and to add a LARGER boost gauge in the clock location.

Sorry to piss off the purists out there, but the sun doesnt rise and fall with VDO.

Hi Chris,

Didn't mean to piss you off or even to be snide (which I didn't mean at all). I'm just a old pussycat, not a bastard, really.

In your message you never stated why you were asking for information, and did not imply that you were going racing with your car. And I do admit that I should have said "replace" your tach, not "add" a tach. Sorry.

So, with the new information that you just provided, and the fact that you've already made up your mind to purchase the Autometer ("before I purchase my new tach tomrrow", your quote), perhaps that's why no one has responded. This has happened a lot on this Board - someone will ask the Board to help justify a purchase that they made yesterday. Most of us like to help from our past experience, but we might find it futile to help others justify a purchase for their peace of mind.

My experience on this Board is that people are willing to help when you ask specific questions. Please see my other posts, where I've gotten annoyed when people don't answer my very specific requests, or when they steal or highjack the thread.

The art of getting a good answer is to ask the right question.

Not meaning to be snide, just making an observation.

Point taken, but the response did sound a little snide. The question Is very specific though. I am not angry but only trying to make a point. I dont need to justify any moneys I spend on my cars. I do much research before I spend it. That is why I asked this question in the first place. Even though it has been handled, and not to argue but I think most would agree it is quite clear even though it didnt get a reponse. I will quote myself from above.

"When you run an Autometer tachometer on a stock 930 ignition system is there any trick to it to make it work with capacitive discharge ignition, or is it the same as any ordinary setup?"

Thanks for your clarification though, and again I am not angry.

Cool.

Chris,

You needn't justify your choice to replace your factory tach ... but trying to pass off use of Autometer by current race teams as a preference [while getting sponsorship money] won't fly too well here, either! Get REAL ... VDO tachs were good enough for the 917s, 936s, and 935s that won Le Mans multiple times!

There is only one Autometer user here that I am aware of in a vintage 911 racecar, and a few others that have used them in the past on other brands of cars. So, really, you aren't asking a question that many here have any experience with ...

The following thread has reverse-engineered documentathion for the 6-pin Bosch 0.227.300.004 CDI unit ... if you need information on the TD drive circuit in addition to the Autometer response to your question:

6-pin SC/Turbo CDI unit repair documentation

Consider yourself lucky that Loren didn't answer this thread!!!

I can tell already by the complete B.S. responses here that there has been a good reason I have been over on the Turbo911 forum for the last year and a half.

Too many self riteous pricks here for me. One cant even state his opinion here without getting a ton of flack for it. I will be sure to warn local club people about posting here. That way some other innocent newbie doesent come along and clearly upset EVERYONE!!!

Unbelievable...................................... ......

Clearly I am at the wrong forum. I will post this simple question back at my home site. A simple question should get a simple answer and not some diagram that still wont help. AGAIN, I DID STATE EARLIER AUTOMETER HAS ALREADY HELPED ME. PROBLEM SOLVED!
Sorry to say this but unless I run into a nicer crowd here like so many I talked to here the first three days, this will probably be one of my last few posts here. I probably know as much if not more than most about the history of Porsche and what makes them so great. I dont need to be reminded of this and never stated that VDO was not good enough to be in our cars.

Very disappointed.............................C

Since you sent me a message asking my opinion, I will echo again, I believe that you have severely over-reacted to all the responses to your posts here. I see nothing specifically inflammatory - except from you!

The Internet is a place where things that are said can be mis-interpretted very easily. I believe that is what has happened here. This is easily the friendlist and most knowledgeable forum in the Porsche community - just don't jump the gun and assume the worst of everyone (as you clearly did with Andras).

Just my $.02, since you specifically asked...
