Just a reminder about the E.A.T. winter sale, save $15

[MarkD]

Hello members,

the winter chip sale ends on Feb. 21, so now is the time to save $15 on the purchase of a chip. Also, prices will be going up soon, as two years ago I had planned on selling most chips for $199 USD + shipping, but had held the price. Now due to the exchange rate, I'll be adjusting the price sometime in the next month.

If you would like a chip, please order by sending a paypal payment to mdsylva@sympatico.ca Any $179 chip on my site will be $164 till Feb. 21.

Thanks

Mark

I don't think anyone bought because you mentioned it, but thanks for mentioning it anyway! I had 4 sales in January.

I am interested however I have a question. (No flames please) What is a non EWS engine? I couldnt find anything about this in the Bentley.

EWS is a security system on BMW's built after Dec. 1994. The key transmits a code that must match the one stored in the EPROM chip. (in the DME). If it doesn't match, the car will not start. More info here: http://www.bmw.co.za/Products/FIRST...t/pro-Theft.htm

Been lurking awhile and really appreciate all the useful information provided.

I've been intrigued by the potential of a new chip. But it sounds almost too good to be true. Will my 1990 525 actually experience a noticeable improvement with EAT chip upgrade? Now that everything else is fixed, I think I can upgrade a little. The car is completely stock otherwise.

Sure it will have a very noticeable improvement. I assume you have the M20 motor? Have a look at your DME number and tell me what it is. I've been testing the m20 chip and had great results. It's ready for release if your DME is 0 261 200 173.

I have a question for Mark. I read the description of the chip for my car. It says that the 94 M60 chip retains the stock rev limiter but removes the speed limiter.

Is there a noticeable improvement in driveablility or acceleration compared to the stock chip? What can I expect?

Thanks,

Both driveablility and acceleration are improved. Do you have an auto or manual? I raised the rev limiter in the manual. The 530 chip is not yet released.

If you have 1 744 050 printed on the outside of your DME, I have a chip that works well. There are many happy customers using it.
If you have some other number I don't have a chip ready yet. (the other number would be 1 744 606 )

KJBCPA, and anyone else considering purchasing an EAT chip for their car. All I can say is you will not be disappointed from the bang-for-the-buck Mark's chips provide. Someone on the board stated "The EAT chip turned my car into the BMW I had hoped I was buying." and I have to agree with that. Try it, you won't be disappointed.

Just out of curiousity, have you compared a JC chip withyour M60 chip, Mark?

No, I don't have a JC chip to compare. Do you have one? I'd like to send one of my chips to someone who has any competitive chip, so they could compare it.

Mark

[MBXB]

Mark, I do have a JC chip in my 540iA. We emailed each other last summer about it. I figured you got hold of a tester closer to you. I've had the JC chip for 2+ years.

Hi Ramon, do you still have your stock chip? I'd like to know what the number on it is. If my chip is compatible, I'll send you a chip for evaluation this week. And, there is a chip for the 540iA I don't have (a different stock chip) So if you have that one I'd like to borrow it to make the version I don't have yet.

Hi Mark,

i have an automatic-will there be a big difference in performance..say hp and rpm..have been hearing about a higher rev and a .5hp increase..is this correct? i can send you my dme number next time around. would you have a chip for this e24(formerly 633csi) which we put a 535i engine from an e28.the dme number #0261200061..

It's in the e-box on the passenger side, just in front of the firewall. Look on Bruno's site (www.bmwe34.net) for details. Look for "chip upgrade".

That DME is from the early Euro M30, in North America it should have the 0 261 200 059. I have made a prototype chip for your DME but I did not release it yet. I may do that in the spring. Typically a chip has more than .5hp increase. (5 - 8 % typical) For your car, it will be a bit less as it's already been tuned further than the NA cars.

Chris, this is the single best investment in my car I have made. The E.A.T. chip gave the car a noticable boost below 3K rpms. I used to own a 944 turbo that was also modified and chipped. When I went to the 540 it was a noticable dog in comparison. This chip has changed my opinion about the car and it is now a joy to drive. I am now looking forward to the next 100K miles!

Hello Chris, there was one response I made which did not get posted in the correct place, I was going to delete it and reply to the correct post (I think it was from you) but someone had already responded to my post so left it where it was.. Please ask again and I'll answer it. (I don't know which question it was)

more drivable, better throttle response. Makes the engine "eager to rev." Can't beat it. Do it!

Hi Kurt,

I've got a small contract job that is taking up my time, there are a few issues left to fix and then I can get back to chip development. Any chips currently not released will be available at the old price or even a special introductory price, so son't worry about the price increase yet. (thanks for being patient)

My question regarding the chip for the 540ia was regarding overall driveability improvements and the affect on gas mileage. Someone has already responded that driveability is greatly improved by your chip. My main question is how much of hit will I be taking in the gas mileage department?

Thanks,

Chris

I had responded to your questions here: http://www.bimmer.info/forum/showthread.php?postid=3659#poststop

You won't be taking a 'hit' as part throttle mapping uses less fuel, and WOT (which is not where you are unless you have your foot on it) uses slightly more fuel.

Mark

[Chris M]

I guessed I missed that post Mark. Thanks for answering my question. I will be most likely contacting you after I have verified that I have the correct chip in my car for the swap.

Hi Ed,
it depends what DME you have. The -061 is already highly tuned and you may need 93 if I enhance it's performance. If you had the 0.261.200.179 you can use 91 octane and my chip.

I am using 91 octane in Arizona. No pinging noted and it gets brutally hot here friends.

My gas mileage actually improved a bit.. but now that I am much happier driving more aggressively (read that as S4 mode all the time) I am back to where I was with the stock chip.

I've been waiting for the chip for my '95 540ia, but beings I live in California and have crappy 91 octane fuel (highest I've found)and pain in the ass smog requiremnets, will this chip (or any chip for that matter) work ok here?

Sure it will, but they recently switch the gas for winter and it seems to have lower octane. I currently have one 95 540iA owner (with EWS) using the chip in CA. I can get you in touch with him if you have questions. When was your car built? I am wondering if it has EWS. I don't yet have my generic EWS chip ready, so I need to read the stock EWS chip and then update it. (I have a little problem calculating the checksum on part of the code where the EWS function is)

Mark, besides the build date(which I think is 4/95), is there any other info you need and when my wife gets home I can take a look.

Hi Keith,
if the car was built in April 95, it has the EWS security system. There is a unique security code stored in the EPROM which has to match the code sent by the key. I had intended to make a generic chip for the EWS cars but ran into a technical problem, and have not had time to work around the problem. The only way I can currently make a chip for this car is to read the old chip for each EWS equipped car. I'll work on a better solution soon. Summary: I don't yet have a chip to send you. Hopefully I can get around it in a month or so. I currently have one field tester for this chip and have got good feedback.

Keith,
here is what I need to know:

1) what is the number on your DME? It should be 0 261 200 404, not 0 261 203 484 (the latter is the EWS DME)

2) the DME should have the number 1 744 050 on it near the number above.

If the 2 conditions above are TRUE, you can order a chip.

Check here for chip changing instructions, it helps you locate the DME also:

I'll offer the chip for the -173 DME for $164 USD, with shipping by airmail included, it would take about 7 days to arrive. I can't go any lower, it's a great deal at that price. (It will sell for $199 when the prices are adjusted in about a month)

This chip won't be on the site until I can get the PRODUCTS page updated. There's an error in the html code that I can't locate.

I edited this page, the price I posted here earlier was incorrect)
