Where can I find a CHIP for 1995 525i?

[Russell]

Mark,
As we have discussed in the past, I have waited for you to complete a generic chip for the 95 525i with the EWS chip. If I understand correctly, you do not plan to do so at this time. However, you will ship the eprom reader to me, I read and furnish you the code, and you can make me a performance chip that will work specifically on my car. Let me know if this is the case.

Mark, I appreciate al the hard work you have done on the e34s. Thank you.

I was not able to spend time to find one last piece of the puzzle required to make a generic EWS chip, (cars built after 12/94 have the EWS-II anti-theft system) but I have a solution. I have bought an EPROM reader that is in the USA. I can ship it to anyone that has an EWS chip so you can read it. Then you email me the file for your chip, and I'll make a performance version and mail you a chip with the EWS code for your car. The reader is currently in Texas and will be there for a few more weeks.

The reader is quite easy to use and it takes about 5 minutes to set up and read a chip. (maybe 15 the first time)

Hello Russell,

yes you understood correctly. I can ship the reader to you in the future (it's currently at another member's home in TX) or I may also be able to arrange that someone with the reader can read it for you but then your car will be disabled while the chip is being sent out to read.

The issue with the generic chip is that when I added code to make the generic chip, a new checksum has to be calculated and I was not able to find the checksum location in the time I spent looking for it.

How do you tell from EWS-II from EWS? My DME shows the chip # as 0 261 200 413 but nothing about EWS-II or EWS.

Thanks for the info but I already seen this site. They don't have the chip for 1995 525i. They have it for 1994 or older but NOT for 1995 year.

Where are you located? As I mentioned, if I can read your chip I'll make a chip with your EWS codes in it.

Contact me directly for more info.

I will contact you directly in a couple of weeks and we can make arrangements. Appreciate your help.

Hi Ian,
yes my M50 chips work well with the Euro models and I have a few people in the UK using them. There is one DME that I didn't make a chip for as it never came to NA. (0 261 200 400)

If your DME ends in 402, 403 or 405, I have a chip for you.

(The Vanos DME ends in 413 but you don't have that one).

Mark

Thanks Mark, I will take out my DME and see what the chip number is.

In Chicago, IL (USA). I really don't want to send in my chip since I use this car as a daily driver. I was hoping someone might carry the performance chip so making a purchase is easy without any hassle.

I can have the programmer sent to Chicago in the future. You can read it yourself and email the file to me.

Is there any software available to the end-user to modify the code on BMW EPROMS? I have a GMC Yukon now and am considering purchasing a 95 540. I already have an EEPROM programmer and conveniently my Yukon uses 27C512 PROMs! I have tunercat that I use on my truck, is there an equivalent for the bimmer? What about for datalogging? Thanks for helping out a newbie.

EAT chip, installed mine yesterday and I could not be happier! Much more "get up" off the line. Simplest performance upgrade I ever did!!!
