Shadow Codes Discussion

GeorgeSmooth · 05-20-2011, 05:59 AM

I have experienced quite a interesting development. I sometimes use the BavTech tool and read some faults on a E92 M3 2011 that has the new anti tuning software installed. What was very interesting is the part where you click to go into shadow codes was blanked out and could not be accessed. Has anyone experienced this with a N54. I am having my software updated soon so would like to know before hand.

perhaps you don't have any so the software grays out the field.

I spoke to my Shop manager about this. He said its called FASTA data. FASTA Data
this is the data transmitted to BMW technical assistance from the diagnostic tester when they are troubleshooting a trouble code, or problem.

They will perform a "Short Test" and transmit the FASTA data prior to programming or troubleshooting. In many instances, the "uncontaminated" FASTA information may be helpful in determining the root cause, which in this case, would be that a piggyback had been installed, tripping the "tuner protection" codes.... even if they have been cleared, because this contains the RAW data that tripped the codes, not the codes themselves.

This has been discussed here ad-nauseum. A search for FASTA will illuminate the subject a great deal for you.
