DIY chip tuning question

[rarudduck]

I currently have a custom chip from Turner Motorsports for my racecar. It works great for the most part but I would like to custom tune some areas. What I have been trying to do without any success at this point is dump the chip so I can emulate it with an ostrich 2 and make my edits. It seems like the chip is somehow uncopyable, which seems really odd to me all things considered. I can dump my stock chip, which I could tune, except for the fact I am not sure how to remove EWS2 from it. That was really the whole reason for getting the Turner chip in the first place.

I realize this question and its answers could be considered sensitive, so if you have any information or even a general direction of how to get this done that you don't feel ok to post, just PM or email me. I figured of anywhere on Bimmerforums this forum was the best place to ask.

TIA,

Robert

Is it seriously odd to you that a company makes a product they have spent time and money creating "uncopyable" by the general public as to protect it from being copied and bootlegged?
really?

Not odd that they would try to do it, odd that it was possible given the fact it is just replacing a ROM chip in a 17 year old ECU.

I really don't want this to turn into a thread about copy protection. I just want to make a few changes to a chip I bought for my race car. I have no interest in piracy or anything of that sort, hence why I asked for PMs. If the chip isn't tunable that is fine, I will just cough up the money for one that is. It is sad that the first thing people turn to nowadays is the "OMG you want to pirate it" mindset... really sad.

wasn't my first thought. I was more amazed by the fact that you found it odd that the chip was uncopyable. you may not want to pirate it, but they have to protect themselves.

Gotcha. I can understand the desire, just didn't realize the tech existed to do it all things considered. The ecu has to be able to read it, so it must be readable in some capacity. Hopefully someone has some ideas. I just need to modify the rev limit and lean it out a bit on the mid / top end. Pretty simple stuff in theory, just don't want to spend $400 bucks on yet another new chip if I don't have to.

Thanks.

:wave ah theory, if we could only live there.


Rarudduck, I know this doesnt help you or answer your current question but might be of use to someone in the same shoes.

Our custom OBDI software $650 with 15% off now for $552.46 provides the type of support you are looking for, need a different rev limit? tad more fuel in the mid range? need a revision after dyno tuning? not a problem, we make the adjustments and send the new chip to you as part of our support for custom tunes.

Interesting. If this doesn't pan out I may be coming your way. I assume you guys can kill EWS and that sort of thing?

I live there. I find it makes things interesting. Sorta like being kicked in the balls.

You are in good hands with TRM.

pm'ed with various options.!

[Brody @ Miller]

Rk-tunes is good, or you can always go with the WAR chip and not have to deal with chips coming from here or there for simple revisions. All the power is at your finger tips with the WAR chip. It's only 389 an comes with all the same support others charge a premium for.

How about me sending you the bin file that you need for your setup for free??? Isn't this what the BMW forum is about helping each other so we can enjoy our cars for less money.

Dude, just PM me with specs that your car is in now and I will send you a tune, then you can adjust it to anything you want.

You can't copy it with the eprom reader because it is not an eprom. It is Xilinx programmable logic device (PLD)

Yes, we would be more than happy to fix that and answer any questions you might have concerning the tune.
