Ok i have only had my M42 for a couple months and already obviously know i have to run premium fuel. I was used to it from my last car which was a 325e with a dinan chip. Now im curious, since i already have to run 91+ octane fuel whats the best chip to get more power out of what im already running. I dont plan on running 93 octane or 92. Is the dinan chip any good it seems to run a lower redline then all the other chips out there. Mark D seems to be a popular name when talkin about M42 chipping. Anyone a pro at this shit because i don't know much. I assume "Dinan" is the big name in BMW performance but does anyone know why you get another +500 redline on other chips over the "GREAT" Dinan.

my 2 cents: Had both, Mark D better...

Hmm good info. Where did you get the Mark D chip?
-
Dinan stuff is O.K., but not the best most of the time. The nice thing about Dinan stuff is it won't void your warranty on a new vehicle. Hence they don't get the power out of the stuff that they could. I've always heard Marks chips are the best but have not gotten one yet...I will though in a few months :)

Good info! Too bad my warranty is already void! Hmm whats the price difference and the performance difference? What flavors does the Mark D chip come in?
-
mark can pretty much make anything you want, but I would recommend his 93 octane chip.

I can't run 93 oct. No gas station around here has that high of octane
-
I have the Dinan, and live in CA so I can only run 91 as well. My thoughts on the Dinan is that the tune is pretty conservative, but all of their stuff is. Im not bashing Mark D's tune, being a tuner myself, I just wanted to slap something on that I knew would be on the conservative side. Lets face it, there isnt a whole bunch of power to be found in our motors, but having the higher rev limiter was #1 for me.

Ya the best i can do is Chev 92 octane and its about 10-20 cents over priced most of the time ( because its fresher gas than wholesaler's gas ).. i have to a couple miles out of my way to not get that extra tax on each gallon. So Honestly i dont want a higher rev anyway.. Good way to blow up a motor, i want it to just be tuned. The dinan chip is cheaper but the rev limiter increase is only 500. Sounds good to me, I guess i should look and see if i even have a stock ECU since i just got the car!

Asking for a friend with no chip.
Could a Mark D 93 chip be used in Europe? We've got only 95,98,99,100 octane gas. I use only 99 and 100.:D

You guys suck! hehe I could only imagine would i could do with race fuel out of the pump!

Actually European Octanes are not the same as North American Octane. That's all I know though.
I have the 93 Octane MarkD chip. I saw a very nice increase when I installed it but then got used to it...then I drove a stock M42...boy was it slow lol. The 91 octane chip is still a very good one.
The M42 is a high reving engine and you won't kill it at 7100rpm, mine has 244 000kms and is track driven and it sees 7100rpm very very often. On the street I'm more conservative but I still beat the shit out of it every once in a while.
Morale of the story, don't let the higher rev limiter scare you and get you to buy a more conservative chip...I think you should go with the MarkD 91 octane chip.

Hmm so its Dinan Chip vs. Mark D's 91 octane. I'll have to do some research on these both, thanks for your guys opinions

man i dont even know how many octances we have here in malaysia....plus a chip from the states will cost a bomb over here..3.375 ringgit to 1 usd....plus its like 2.50 ringgit per hour to work at mcdonalds in malaysia...work hard...
-

There are places to get it from locally...
My parents live just outside of Minneapolis and one of their local gas stations sells higher octane gas. Point is, they are around! Just not common.
-
Also, I'm a big fan of Dinan chips. They certainly aren't the highest for HP gain ratings, but they always work.

Where in the power band do you see most of the difference?
-
I'll throw it out there since no one else has mentioned it...Jim Conforti is well known in BMW circles as turning out great chips. You can get them from Turner Motorsports, Bimmerworld and a few other places. Generally slightly more aggressive than a Dinan chip, but still a safe bet. Usually run around $250.
Whatever you do - DON'T BUY A CHIP ON EBAY!!!!
Don't forget to tell us what you get and how you like it.
-
Conforti and Dinan are both good, but Mark's chip is wayyyy better. i got the 93 octane, and the power difference was amazing. I can now pull cleanly in any gear (except may 5th due to the lack of power) from 1000 RPM, where the original tuning was very roulgh that low in the rev range. The midrange is much better as well.
-
Has anyone actually had any problems with the "eBay" chips? I bought one last year and I have put over 30,000 kms on with it and I have had no problems and I regularly take it to 6900 RPM. It seems to be fine and I run 91 octane Shell or Esso gas. From my understanding they were just burnt Dinan or similar tuner copies.
-
I actually had a stage 2 ebay chip in it from the previous owner, who is a bit of an ebay addict. The chip wasn't bad as far as improvements for the price go, and the low end was great. The problem is that the chip ran REALLY rich. So rich that a new set of spark plugs went in about 10k miles and the cat died in 2 years. With forced indution or something, the ebay chip might actually work pretty well.
-
I have just put in a 93 octane mark d chip, I ran 95 octane(euro) and I now run 98 octane.
I can not with hand on my heart say that there is a difference, I belive it is, but not much.
But to rev it to 7000 makes a world of differense, and it is strong all the way.
No regrets.

Thats probably one of my only downsides, like at idle and around town I think my car is running a tad ritch, mostly becasue tehre is always block power in my exhaust tip, but it really hasn't hurt my fuel ecconomy. But yea, for the $35 or so odd dollars I paid for the chip, it all seems to be worth it.
-
The problem with ebay chips is that you don't know what you are getting. Could be a great chip, could be crap. With Dinan, conforti, even independents like Mike D they have to turn out good chips because their business is dependent on it. Ebay sellers can sell and say whatever they want because there are almost no repurcussions. And with a chip unless it screws up your engine how do you know? Ship me the wrong water pump and I'll know the minute I open the box. Ship me a bogus chip and without head to head dyno testing I really don't know what I got.
A buddy of mine paid $50 for a used Dinan chip on ebay. He was disappointed that the car didn't really feel any different. When he took it out after a few months he discovered that it was really a stock chip with a dinan sticker applied to it. Of course by that time the ebay seller had disappeared (or more than likely was selling under a different user name.) Just remember ebay is a buyer beware world.

i have to get 93 octane here 89 is the next best so i dont run it. anyone know how much the markd 93 octane chip helps?

First and foremost many thanks to Arron Green (agreen) for volunteering his low mileage 318iS for the chip testing we are carrying out here at Evolve Autmotive.
The day started with the first dyno run at just under 136 bhp which is bang on the power for one of these.
We then moved onto testing a few chips.
The first test showed an abismal gain of 4 bhp when the quoted chip should have given an amazing + 18 bhp!
Had a look at some other chips we got hold of and compared them on our program and there was little point in trying them out as the ignition timing and fuelling values were pretty much the same and in some cases exactly the same (ie: Copies).
We then went about testing two of other chips which are under the Evolve Brand that had never been tested but the feedback was very high from customers.
We do quote around 7 bhp from one of these so we didn't really expect anything more.
To our surprise the gain was just under 12 bhp.
The second more agressive chip ws a little too agressive and we decided on not dynoing it at all.
Arron was with us all of the time and we done every test in the same way with intake and ambient temps very close to each other.
Graph of Before and after with the Evolve 318iS Chip:
(http://i148.photobucket.com/albums/s38/davem-sport/e30318iS.jpg)
On the road Arron gave the same feedback as others who have used this chip - considerably better part throttle power especially at low rpms, smoother power delivery and a noticeable gain under full load driving.
I'm sure Arron will give his own comments.

This is a great definite answer to what a good chip does to the M42 instead of all the claims people state.
The low down torque gain is crazy
-
that looks pretty good.. anyone have a sheet with the markD 93 octane or should it be around the same?
-
a friend is letting me use his dinan chip for my car.. just got to drive around for a few minutes and it really is nice. its forsale if anyone is looking for one..
seeing how this one runs really makes me want to get the chip i want

Just thought I would add a not about ebay chips. I have had 2 X 325E's, 2 X 325I's, 4 X E36 325IS's and 4 E34 525I's, a 735I and a 635CSI. I have used, TMS chips, Dinan chips and the cheapo ebay chips (xg-motorsports). I can definitely say that the cheap ebay chips gave the eta's the same performance gains with no adverse effects as the dinan chips did. I actually had 2 eta's at the same time one chippe dwith dinan and the other with a cheapo and the performance was identical. I have only used 1 other ebay chip on an E36 325is and there was a very noticable gain. The tms chip I used was for my S50 conversion I did and it was the kit with the 3.5" maf so there is no contest comparing that one. All of my E34's had dinan chips but I woul dnot be afraid of running a ebay chip from the right seller (in this case xg motorsports) I just ordered one for my 318I sedan and will post some butt dyno results when it gets here.

I'm interested in the xg motorsports chip also .
Look forward to your butt results. It doesn't say what Octane the chip is made for.:confused:

I sent him an email and he stated that it is for 91 octane like the rest of the, Also emailed me a set of instructions. Funny thing is that the instructions are written by ac schitzner. Maybe its just a copy of the eprom. No complaints from me on any of the other chips, im sure this one will be just as good as the others.
Heres a copy of the email.
Installation Instructions
Removing the ECU from the car
E30 3-Series
1.) The Ecu is located inside the car. Open the glove box. Remove the pins securing the glove box door to the mounting straps. You can let the glove box door rest on the floor
2.) 325E: Remove the Phillips screws on the front of the black plastic cover at the top of the glove box. Remove the black plastic screws at the rear of the black plastic cover. Pull this panel down and set it aside.
3.) Remove the 10mm bolts or the Phillips screws securing the engine control unit
(ECU) to the dashboard.
4.) Unclip the metal fastener locking the wiring harness into the ECU and remove the
harness. Take the Ecu to your workbench.
AT YOUR TABLE
1.) The Bosch part number on your ECU must be 0-261-200-175. If this number is not printed on the label – DO NOT INSTALL THE PERFORMANCE CHIP, your car will not be happy!
2.) Place the ECU on your table with its part number label facing down. Use a small pocket screwdriver to pry up the six locking tabs securing the ECU’s cover; pry each tab up only enough to insert the medium screwdriver. Use the medium-sized screwdriver to finish prying the tabs upward until they’re vertical. Be careful; the tabs will weaken with repeated prying. Remove the ECU cover and set it aside.
3.) Locate the socketed chip on the printed circuit board. Clue; the chip is secured with a white plastic clip in the shape of the letter “H”.
4.) Remove the retaining clip by inserting the pocket screwdriver into one of the small slots in the clip’s side and prying toward the other slot. The retaining clip will pop up on the side in which the screwdriver is inserted. Use your fingertip to hold that side up while you repeat the process for the other side. Set the clip aside – it will not be reused.
5.) This step is VERY important! By removing the original chip, examine how it is oriented in its socket. Particularly note where the “divot” is positioned. On some cars the divots maybe on opposite ends from each other. On others they may line up. IT IS CRUCIAL TO YOU THAT REMEMBER WHICH END THE CHIP’S DIVOT IS INSTALLED ON! Remove the chip from its socket with the pocket screwdriver. Insert the blade between the chip and the socket and pry gently upward. Alternately pry each end of the chip until it is COMPLETELY loose. WARNING: pry the chip from the socket – not the socket from the board! As you remove the chip from it’s socket, grasp it by the chip itself and not by the pins. THE PINS ARE FRAGILE! Keep the stock chip – you may want to reinstall it later.
6.) NOTE: the pins of all computer chips are very fragile! Every chip that leaves AC Schnitzer is inspected for quality. If the pins on the module, encryptor board ever become bent or tweaked DO NOT attempt to bend them back into place. AC Schnitzer will not be responsible for broken or damaged chips. Call us for instructions on getting a new chip sent to you.
7.) Remember the Performance chip must be oriented in the socket in the same fashion as the original chip was (this is why step 5 is critical). The chip has a U groove on it. This is the divot end. Rest one row of pins from the Performance Chip on the socket. Ensure that each and every pin lines with a corresponding socket hole. If each pin lines up then gently push down on each row to LIGHTLY set the chip in the socket. Avoid bending and flexing the printed circuit board while inserting the chip. Apply firm but gentle pressure on the chip during installation. Push down on the chip until it “clicks” into the socket. NEVER bend any of the pins to ease installation. Visually verify that all of the Performance Chip’s pins are in their corresponding socket holes and that all of the socket holes have pins.
8.) The white plastic retaining clip will not fit over your new Performance Chip. This is not necessary for the vehicle to run. Reinstall the ECU’s cover in the reverse order of step 2. Use the pliers to bend the locking tabs back into place.
9.) Reinstall the ECU into the car and plug the wiring harness back in. Start the car and ENJOY!

38 bucks looks like a very good deal if it does what they say .............
For under 50 bucks with shipping I might get one and put it in in the spring.
Xmas for me :D

Had an ebay chip in mine, was great for 6 months then just as people said to be leery of, it fried the ecu...
Pay the extra and get a good chip IMO. I coulda got a markd chip for what I ended up having into getting the ebay chip and then the new ecu.

my question is what about emissons performance. Dinan, IIRC is certified legal in 50 states for emissions.
Others may or may not have effects o emissions.
My dinan chip passed with flying colors on the dyno test...

It seems to me that if the chip was to blame, it would have fried the ECU right away? Maybe I'm wrong. You sure it wasn't a bad coil, I've heard they can cause damage to the ECU
-
I have a dinan Chip and I really like it. I always hear great things about the mark d chip and am really thinking about picking a 93 chip up from him.
-
Well, I just bought that XG Motorsport chip. I gonna dyno it within few months time (april, may maybe).
-
i ordered the markd 93 oct chip i cant wait for it to get in.

Thanks for ordering one of my chips instead of a clone from eBay. All those guys do is copy someone else's work and sell it to you. I've got more TENS of thousands in equipment (and countless hours of work) than you can imagine invested to develop my chips. (actually I should change the word "investment" to "spent" as it's not really making a positive profit. :(

The quoted dyno results don't show air/fuel. Their results are inconclusive without that because, sure you can make lots of power but how close or over "the line" are they to making the tune unsafe. That tune could be dangerously lean and timing far advanced, that would make power but be extremely unsafe for the motor, IE detonation..
I am only commenting on this because their claimed power gain seems unrealistic to be safe.

Mark,
Had I seen your chip first, I would have gotten it. I bought one from ebay, and you saw the results. Although, all in all it was only $50, when you did your GROUP BUY, it would only have been $150 bucks more. WHich is a steel for afew more HP.
Maybe I can unload mine locally and get one from you. Being a local bike shop owner, I know how important it is to support the locals and your sponsors. So, a sincere apology, and look forward to seling me one shortly...

Hello Hodge,
my post is not so much about asking you to support locals and sponsors (I'm in Canada) but a complaint about people who buy copies of other people's work from eBay sellers who have only spent $50 or so for some cheap programmer they use to clone the work of people who spent thousands on development.
If it wasn't for people like me developing what nobody else had and offering it for a reasonable price, there wouldn't be the opportunity to buy the m20 and M42 chips (among others) that work very well.

I ve just buy a chip from evolve ( brother gift from christmas =)))))... and i must say...more power at high revs...and more responsive a 2000 rpm...even the sound of the car(dynomax turbo exhaust) is different ( more raccey)..and the price is very good when comparing with others brands here in europe.
Best regards to bimmers fans =)

to Mr MarkD I want one of you chips but from the looks of it it seems you dont sell any 93 318is vanos chips? maybe i looked wrong? i dont know but what does your chip offer as far as hp/tq and i dont mind the 93 oct cause am all for it
