Limit to how many times car can be coded - BMW 3-Series (E90 E92) Forum

kfrazie1 · 05-16-2012, 08:55 PM

Was speaking with an ind tech today and we were talking about coding. He mentioned the car can only be coded a certain number of times (15 or so) before modules are damaged. Any thoughts?

Bullshit mine was coded about 100 times when i was learning to code two years ago , and not a single module get damaged

maybe he was thinking re-programming?

Maybe... But he was still wrong. Im doing coding and update firmware on modules for two years as i mention before, some cars have major problems and was updated many times in this years ( my clients usually stays with me) and they have their car update many time ( as many as daten files versions were out from this time) again not a single problem.

Re-programming can only be done a set number of times I believe. WinKFP will give you a warning about it. Coding is unlimited.

WinKFP and/or Progman will give you a warning something like: "Programming Module xxx. Module can be programmed xx more times". However, I've seen the exact same number upon multiple programmings (I had to program my ABS several times because I fat-fingered the VIN [and the ABS takes the full VIN, not just the last 7] and it read the same every time). I'm not sure if it is a bug or some internal "health" measurement of the ECU, or what, but it seems that the message is BS.

Yea I see the same thing.

It always shows me that the module can be coded 1 more time..but I see that message all the time when coding the module again.

Is it true that the dme can be flashed 30-50 times? Flash meaning "vin flashed". I don't think tuning the dme counts as a cycle as you arent writing the vin number again. I heard that writing a vin results in a recorded flash number. Confirmation?

Winkfp always shows that , if you use autologic or isss online this "warning" didn pop up.

Flash memory in general has a maximum number of flash reprogramming events it is designed to handle. However for consumers it's a non-issue. For folks like me who design automotive ECU hardware we re-flash lots of times for a given vehicle program, and we still don't come close to that limit (lmits vary by flash technology and supplier).

Bottom line, I don't think you have anything to worry about.

Now, if BMW puts in their code to limit reflashing, that's a different issue and they've decided to insert that limit.
