What it is
ME7 is Bosch’s Motronic petrol ECU of the late 1990s and 2000s. OpenRemap’s examples: the Audi S4 2.7T biturbo (ME7.1), the Audi A3 and VW Golf 1.8T (ME7.5), the Opel Corsa D 1.6T (ME7.6.2), the Porsche 996, the Ferrari 360, and the Peugeot 206 and 207 (OpenRemap).
What a file from it looks like
A whole ME7 read is between 64 KB and 1 MB, depending on the variant. The Opel Corsa D’s ME7.6.2 is 832 KB (OpenRemap). Some Peugeot reads hold only a calibration sector of 64 KB or 256 KB (OpenRemap).
What the numbers look like
The software number is ten digits starting with 1037 (OpenRemap). Unlike most Bosch diesels, ME7 keeps its hardware number in the file, in an ident block that starts with the letters ZZ at address 0x10000. The Peugeot 256 KB sector reads are the exception (OpenRemap). Bosch petrol hardware numbers start with 0 261 (Autotuner).
One detail for the curious: Marelli’s ME1.5.5 also puts a ZZ block at 0x10000. OpenRemap tells them apart by the third byte of the block (OpenRemap).
What EcuInside reads from it
The family and variant, the software number, the hardware number from the ident block, the carmaker’s part number when the file has it, and the size check.
Full read or partial?
The size rule here is wider than for the diesels, because ME7 variants differ so much: from 64 KB to 1 MB is a whole read. The result names the variant, so you can check the size against it.
Have a Bosch ME7 read? Drop it on EcuInside and see its variant, its numbers with the bytes they came from, and whether it’s a whole read. Free, and the file isn’t kept.
