The answer to all your hesitations!!!

[s-man]

Hello to all....To day is a landmrk day in the progression and painstaking time spent on my 73 s targa with mfi. I just wanted to let all know that all the reading in thisd g-d forsaken board cannot and will not cure the "plague" when trying to deal with a poorly performing mfi system.

I have read countless yammerings over and over, kind of like a song in a loop, yet it seems that more often than not the gospel of the "so called experts" never bears the "real fruits" the could be acheived.

While I do beleive that it is difficult at best to diagnose a car over the net, it should never be forgotten that the principles are static, they remain the same. For example, fuel supply, spark, ignition timing and air flow etc are the main principles in the combustions process, yet several of these will impact on one another if not in proper calibration.

It has been my beleif that some of the "hot dogs", whom are truly intriguing in there words, sometimes lack the logic to post necessary information, merely allowing many members to keep chasing their tales.

It is to day that I have decided to make this statement due to the fact that I at times have been caught in the trance of following the crowd. Luckily, I have nto spent hundreds, or even thousdands as some of you poor spould have on my car,becaus if you really thing about the cause and effects of fuel, spark and ignition, you'lle find whatI have to day.

No more sputter, miss, backfire or anything of the like. It was never the dizzy, fuel supply or any other nonsense that you have come to read over and over again.

What brought me down this road was some recent work I had performed on a 72 bmw 3.0 cs. I knwo its not the same system, but I gave me some ability to get some perspective on another Bosch system. remember, fuel , spark, air.

I kept rolling over and over in my mind, what is the basic difference in the mfi system that plagues we owners v.s. carbs, and even some carb guys too, the one thing that I rarely ever see a suggestion to , that is air.

Thew dybnamics of the air charge is crucial, basically it is the only adjustment that has no real easily defined process for the amateur, too may peple make changes, adjusments to fuel and gintion related items, yet rarely tune the air velocity to match.

Upon relaizing that I myself had not paid enough attention to this, even though I have always owned a syncrometer, any and all changes in Pupmp tuning must be accomoanieds by a pass with the sych.

I know that I am not much different that many of you others, I have read many egaggerations of peple and there toils.

So the moral of the story, ensure that the basics are all in check in the ten commandments, and anytime you futz with anything,howevewr minute, pull out the sych. and if you haven't one, dont even bother trying to do anything without it, you might as well use a cig. pack to set your points.

Ta ta... I invite any and all remarks.......

I SOMEWHAT AGREE.

ONLY THE OWNER OF AN MFI CAR WHO WENT TO ALL THE LEARNING AND TRIALS CAN HELP OTHER MEMBERS.

I choose to remark that you should change your posting name, so it doesn't resemble that of a frequent visitor here who knows what he's posting about...This, just my humble opinion. mind you...

[Rot 911]

S-man, me thinks you dost yammer too much. If you had done any search at all on this board you would have found the mantra of both myself and the other past and present MFI owner's has been to always tell anyone with an MFI question to read all the MFI articles on the Pelican Tech. section beginning with "Check, Measure, Adjust."

[CamB]

Has this fixed the hot-starting problem?

[s-man]

You betcha!!! Car starts without any problems at all.

I just wantd to comment that after the sychronizattion, the whole curve straightened out.

Remeber, "check measure adjust".......But if you havn't got a syncrometer, don't bother!!!!!

Betcha no one ever told you that Big Guy!!!!! It's just the real deal!!!! No peel.......

"Whats the difference btween a mechanic and a dentist?????" "The dentist knows what he's doing!!!!!!"

Shotgun anyone???????

[pwd72s]

For the information of all...I just got a PM from this "s man". I made the decision to delete it...with no response. Of course, what you decide to do is up to you. Me? I just got a new addition to my "ignore" list. The 2nd addition...

[Vipergrün]

S-man (not to be confused with Early S-man),

Begin rant -

I'd be really careful about how you choose to criticize folks on this board. We all know who the guru's are and I, for one, respect them all. You may have solved this particular problem *yourself* and have chosen to gloat about it, but you may find that these same folks will choose to not answer your questions next time. Who knows, perhaps they thought your solution was too simple to mention, I don't know.

This is a community of give and take, with most giving more than taking. Remember, the mechinics on this board are not being paid for their kind services and are volunteering information. Is it all 100% accurate for every situation? Of course not, but what do you expect? If you want that you should take your car to a shop and pay the full price.

End rant -

I'm with " bb80sc " on this one...and I respect everyone who attempts to help me..I'm lucky to be here, and I'll never forget it........Ron

(sigh) I don't think I personally ever offered you advice.

Either way, to recap:

In prior posts you have said you followed "Check, Measure and Adjust" carefully.

However, it appears this excluded going back over the check list - a fundamental premise of "Check, measure and Adjust" (this is something I have picked up only from reading the BBS - I don't even have an MFI 911 and haven't tried to understand the BMW yet).

Its page 10. Correlation and synchronisation is at #9 in the list after virtually everything else (especially timing). There is wording about never deviating from this sequence.

And "we" - the BBS collectively - are to blame for your own oversight in the first instance.

Appears to be a Canadian "dentist" who just doesn't understand the English language! Not that there aren't any Canadians on here that do, there are. This one just obviously doesn't. At least I can't seem to understand his rendition of it! I resent his statement as I have been an advanced level certified master automotive technician for over 25 years. My baby brother is a dentist. We have a mutual respect for each others professions.

[Bob Goding]

I guess I must be one of those " poor spould " as I have surely spent thousands on my Porsche.- Must be a Canuck term!
Its not on Waynes list of naughty words so it cant be too disparaging.
Nice weather up here Cam.!!

[CamB]

Weather's actually ok here - started about when you left

As a Canadian, with a father for a dentist, I feel pretty sure he isn't a dentist.

[Early_S_Man]

To my surprise, my w3dp0's are not so nice, sooty and black,

Funny ... I would never have guessed that the use of 'too cold' spark plugs that were fouled would be 'judged' as a MFI adjustment problem!

A search of the Pelican archives would have turned up several suggestions to use NGK spark plugs, and suitable heat ranges for normal street use, as well as high-speed road/track use.

[Matt Smith]

Cam has answered more eloquently than perhaps I would have.

I'm very happy that you have finally learnt how to read the Check Measure Adjust book. The realisation that you must do what it says is an important one.

Most of us here on the Pelican board have no idea whatsoever how to actually make our MFI cars run, so we pass on B.S just to make ourselves feel better. I wish someone had told me about this "air" thingy before now: it sounds rather exciting!

If you don't bother to think about buying a synch before you bother listening to all this bad advice, then don't bother us with your childish complaints.

[Jim Sims]

Just sounds drunk to me. Jim

[Fishcop]

Funny enough I just bought a synchrometer and can whole heartedly agree with it's use....makes things much easier than guessing.

And where did I get the info I needed to know I needed a synchrometer? Right here

Sorry S-man that you're not happy with the good-willed information you've solicited from the board, but disrespecting people that generously offer what is in some cases expensive help (at a shop) for free will not endear you to the majority of the board. A smarter response to the board would have included a constructive account of how you came to correct your MFI problems and a list of stages you proceded through to fix your problem would have been of far more help to the general board community. You would have scored yourself some kudos.

Glad your car is running well now.

Cheers

[Matt Smith]

He he. Fishcop, I just read my reply and yours again and got a reality check. We're nearing the end of day on Friday at work and you're about halfway through? That's why I'm grumpier. Time for a beer.

[Fishcop]

I've just spent the day up to my nuts in mangrove mud, so a beer is extremely high on my agenda!

I'll crack a cold one for you
