Hi

Question , i am trying to tune a old race car , that have a "bastard " sw , It seems to be a "bosch-motorsport alterd sw for regulated racing purpose "

I have not found any other stock software that matches this one and i can alter some minor things in the sw , but other areas cause the sw to go into limphome , with a max rpm limiter of 2000 rpm .

wish to get a straight boost of 2500 mbar Abs all the way to the limiter that i wish to set at 7250 rpm , but the sw intervents to do it correct .

 I use  CMD for flashing , with CS corr , and have also tryed to BDM it with Winols and the CS corr - no difference

Best Regards

Any ideas ?

attach your mod file please, so it is easier to see if you forgot something or if the own approach would have been the same.

Hello Claus,

Next week I will try to program the exact same ECU, maybe we can share experiences. I also have an original ECU with the 330hp "mod" from Seat Sport.

where are you guys racing ? I thought Tuning ECU is illegal in Copa ? :)

Hi, as the mK2 Supercopa is not elligibly anymore in the official Seat Cup, we race it in various series where we can basically do whatever we want to the ECU  ;D

Claus, I have had the joy of tuning a newer firmware version of the Bosch Motorsport Copa ECU. Had no issues like what you describe - that was about a year ago.
Your version seems ok in terms of checksums too in Winols. Everything is there.
Based on your description, what is happening is a checksum problem. That is the only case when MED9 ecus produce a safe mode and allow you to go only up to 2000rpm.

@Claus:

I see that you modified LDPBN, LDRXN and KFLDHBN. And then there are a few more changes in the hex that I have not yet defined, can you please explain?
