ive read about the chips but it seems there are different ones for different years and engines,mine is a 1991 850i,if i wanted to chip it out which should i get and what can i expect without modifying the intake or exhaust?

Wokke chip. Check the archives. Best bang for your buck! Highly recommended!

Have wuffer's Version 2 chips in my car, just upgraded this last saturday and even from version 1 to version 2 there was a big noticable difference. I STRONGLY advise you get them. He has a limited quantity so act fast. I have a 91 myself. Go to www.wuffer.net (http://www.wuffer.net)

^^^The chip is actually not Tom aka Wuffer's chip... He doesn't make chips :D It's Wolf's chip, known as the Wokke chip.

Wrong dat!! Straight from the Fatherland: GERMANY

Thats not what Tom said on saturday when I was at his wrenchfest :nutz:

lol

Wuffer's Version 2... "He has a limited quantity so act fast." How interesting...I am sure Wokke must be selling his stuff through Wuffer....

I've sent a few to him because my/his customers had them installed by Tom.

do the chips look like on the picture below. If yes, than they're mine, if not they are ??? I'm sure Tom knows that I'm in Germany :stickoutt

Limited quantity? Please don't tell me your running low on those Wokke! I am going on vacation next month and can't budget the chip yet, but I gotta have it....need...more...time....
:cashwalle

no worries. It was said, that Wuffer is running low. I have enough.
Enjoy your vacation.

how much do these go for? is this a diy install?

a complete V2 set incl. shipment via registered mail is US$479,-
V1 set (for those who don't need the much more agressive throttle responce of the V2) is US$329,-

I tried the Ver 1 EML chip, and found that the car had lost about 400+ rpm of throttle control when coming off idle. Made it seem hoppy, though had really just lost fine throttle control coming off idle. This also made cruise control jerky at lower speeds settings. Particullary noticable in S3 mode.

I didn't notice any other benefits other than the off idle jump, perhaps not a benefit.

I removed the Ver 1 EML chip and reinstalled the stock EML.

Wuffer had heard of this same problem before, and he mentioned a sensitive throttle issue that BMW had on some early 850's.

I was wondering if the Ver 2 EML had fixed this problem or exaggerated it? Should I try the Ver 2 EML?

sure it is my V1 chip? Can't find you in my data base with location Champaign.

Wokke,

No, I don't think it is. I believe it is a copy of your early EML chip.

Maybe you were confused with Tom's selling of the Phoenix Motorsports parts which are out of England?

Wokke,

If you did "buy" a copy of Wokke's chip, then you got what you deserve.
This is the FIRST time I have ever heard of "negative" results from Wolf's chips. You should also be aware that some of these "performance" chips that are offered on Ebay for reduced prices are actually a direct copy of stock BMW E31 EML chips.
If you did purchase one directly from Wolf, he is one of the most honest and trustworthy guys out there and he will make it right.

Good luck either way.

I bought the chips off ebay, over a year and half ago. And at that time was when I first heard of Wokke's chips. My car had had Dinan chips installed years before. Back then everyone was saying that Confortti chips were the way to go. I was looking on ebay and found a number of chip marketers, and thought that most where selling the same chips with the same programing. I did not realize that Wokke's chips were of his own design, only that he was just one of the markerters trying to make a buck and selling for what they could. The chips I bought listed the same specs as the Wokke chips also on ebay at that time. All this before I was at all active on the Forums and "knew" of Wokke.

So apparently no one else has noticed that coming off idle with a light foot causes a jump in the the RPM of about 400 or so and not a smooth increase in RPM's.

The issue that alerted me to bring this up to the Forums was a description of another Forum member's car as being really "Hoppy" afer installing the Wokke chips. That is exactly how I would descibe the "sensitive throttle" issue that BMW apparently had with the early 850's and that I had with the EML chip I bought. I have reinstalled the chip that was in the car when I purchased it. It appears to be stock? At any rate it now does not have a sensitive throttle responce.

So my chip must not be a Wokke copy, but a copy of an early BMW chip that had the sensitive throttle problem.

I'll have to save up for a Wokke V2 EML chip.

Thanks for the help.

...it sounds to me like you got "duped". The V1 Wokke chips would have shown a slight improvement over the DINANs, and the V2 chips - well that is like night and day.
Sorry you had a bad experience. You will like the V2s when you get them....

So sorry if this is a silly question but just to be sure, From eBay the chips selling from the eBay user id, wooke_2000, are the good ones and not crappy knock offs? $479 or are they available for less elsewhere, doesn't look like it but I just thought I'd ask?

wokke_2000 is my ebay alias (wokke is blocked unfortunately).
If ordered directly the cost for insured shipping (US$30,-) is included in the US$479,-

P.S. It is NOT a silly question :D

There you go sickle, you can't get much better than a fast response directly from the source. Is this a great BMW board or what?........ :stickoutt

I have a set of Wolf's chips (V2) in my 91 850. My car had the issue of the ~300rpm "jump" since I purchased it. It had the chip replacement BMW did in the 90's to help with the problem. After installing the Wolf's set of V2 chips, yes, the car is more sensitive - but rather like the difference you would have by driving grandma's old chevy wagon as opposed to a corvette. After getting used to it, I really like the response. It is even more smooth after I did some maintenance this weekend - I replaced the distributor caps and rotors (among lots of other things). I also own a CSi, and now the 850 drives much more like the CSi in terms of engine performance.:redspot

And - I'd like to echo a comment above. Wolf is a great guy to do deal with. I happened to get a bad chip, and he replaced it right away - no fuss - no issues.

Thanks again Wolf!

absolutley correct tx because i had order chips directly from wokke and one of the chips(dme 2) was damaged in the shipping and he sent me another free of charged and it worked perfectly fine and the car has so much throttle response and accelerating. he is one of the most honest businessmen that i have ever dealt with. the other dude got dupe big time buying fake cheap replicas of wokkes original chips but then again, he didnt know so its not his fault.

:kissthanks a lot guys for all the compliments

Does the animation looks like a BJ or is just me :devillook I know call me sick but I could not resist....

thanks a lot guys for all the compliments :bj

what is BJ ? I did edit it, just to be on the safe side :stickoutt

BJ= Blow Job . That picture is the visual of a BJ if you ask me.... Don't make me go into details.....
Is not a mechanical term at all :devillook is something that you do in Vegas.... Kidding....

I'm glad I edited it. :eek:

Hi, you guys seem to know what you are doing. I just bought my first 850i, 1991.

Almost immediately after starting it starts idling at about 900-950 rpm. I have not checked the EML or the chips, but I was told tough hav not checked that the car may have had a chip swap. Would they up the idle rpm? if not any idea of how to trouble shoot?

Thanks

Your idle should be normal regardless of chipping.

Btw, welcome. Start another thread and introduce yourself to the forum members.

Cheers

vacuum leak somewhere (very likely suspect are the intake gaskets).

Thanks to both of you. Yes I am new to the forum, still figuring things out.

... Yes I am new to the forum, still figuring things out.

You definitely found THE best place for that. Welcome to a crowd of real enthusiasts.

Hi, Today, I had the chance to monitor the idle thing. When I start the car it idles normally at 700 to 750. Once I dirve it and it warms up the idle is almost a 1000rpm and stays there. If I stop the engine, and while still warm and start again. it starts at 750 and within few second starts to smoothly climb to about a 1000 again.

I took a very quick look at the a couple of the vacuum pipes without removing much stuff, nothing see disconnected, but I have not spent enough time on it. I will have much of next weekend to work on it.

But just to get your opinion would a vacuum leak have these symptoms only when warm? also when you said the intake gaskets, you meant after the stepper motors right?

Thank you very much.

P.S Let me know if you prefer I start another thread.

IMO definitely a vacuum leak. The reason for the high idle occuring only when the engine is warm is due to the expansion of the various parts. When cold the leak is "closed". Check part #5 in below picture. This gasket likes to go bad. And of course parts #10 and #11 as already mentioned above by someone else.

You guys are amazing. thanks! Is hould probably be able to test that with compressed air or something before I take it apart. I will report back next week.

that's what we're all here for - to help each other.
There is a much easier way to check for vacuum leaks than using compressed air:
Run the engine until it is warm.
Take a can of brake cleaner and spray it on every spot where you think a leak might occur, i.e. all gasket areas. If all of a sudden the engine rpms go up you've found the leak. The brake cleaner will be sucked in and acts like additional gasoline.

Hi I had the chance to spend sometime on it . I have checked gasket number 5 on both sides of intake and both side of engine and as much as i can got some brake fluid on the 10 and 11 gaskets (not all around), no change in the rpm. I now doubt that the leak is at these gaskets. I checked the two vacuum tubes just after the step motor on both sides of engine, no leaks there either.

As I was working I accidently disconnected a wire that I think energizes the injectors on one side of the engine, and the engine was idling perfect at around 600, and I thought I had it! Amazing how this car can runs only on one side of the engine working. As soon as I connected the wire the rpm within 20 seconds climbed back to 1000 rpm and stayed there. It is clear, the EML increases throttle to get both sides of the engine in sync, to compensate for a leak on one side.

The part that made the most differnce in idle was a tube that connected the intake just after the step motor to the intake just before the step motor (like a bypass), but it has tee and connects somwhere else?. If I squeee that tube the rpm dives, I am now looking for schematics of that section for more clues as to what that does and to see if anything is wrong with it.

Any other ideas? It may still be the intake gaskets 10,11, but I would hate to take it all apart and it turns out not to be the problem.

Thanks

thanks fellas.

much appreciated btw.

you wanted to use 'brake cleaner' in a spray can... not 'brake fluid'. Gasket #5 is on the back of the intake plenum. Have a check engine light on ?

Those gaskets seem to be fine. today I tried propane gas all around gaskets and pipes. The leak must be somewhat small because I cannot hear the difference. I took the the injectors and fuel rail off on one side, couple of the nuts were not tight all the way on the intake manifold. AS I was tightening one bolt broke:(, and the other tightened fine. Instead of taking everything apart, I am going to get a coupler and retighten it that way. I don't think it is the manifold gasket. I checked all other tubes. are there vacuum tubes on teh rear end of the plenum?

If I don't figure it out this weekend I 'll take it to the dealer. no engine lights, it driver and handles great, but when I shift it to park or nuetral the rpm is 900-1000 and stable, it should be a bit lower.

Thanks for the support.

I hope this is a typo. Brake CLEANER you need, not brake fluid.

Yes meant brake cleaner :-)

I really wanted to find the leak before taking out the manifold. If I do take it out aside from gaskets 11 and injector cleaning and o rings anything else I should plan to replace since I am at that section. Thanks

Funniest thing just happened. I was at the BMW dealer picking up some parts. Iasked a service guy about bringing the car in to check the high idle problem. He said it was normal for the 850 to idle between 800 and 1000 and unless ihad a check engine light not to bother.

What does your 850 idle at once warmed up. Thanks
