Anyone have an ECU for sale?

[Jim Haseltine]

The question then is - whose stage 3 map? The last 5-10% of the work involved in creating a map is getting the checksums to balance. Back in the early days of 'chipping' and remapping ecus a company that doesn't exist any more offered a remap for the quattro turbo MB and 200 turbo MC engines which had a duff checksum, Nothing really wrong with the mapping and you'd never know it wasn't 100% until you tried to trigger the ecu self-tests or dump the error codes and got absolutely no response.
