 Re: ecu remap
No, piggy backs are not detectable digitally. They can be sods to remove though, it's not always the ten minute job as suggested. And you will be tampering with electrical connectors, which might be noticed.
Piggy back ECUs are really not a good idea though. They're crude devices which interfere with the ECU's operation on both the input and output side.
It's possible to completely wreck the emission control systems on a diesel engine by using these for example by causing the particle filter to clog prematurely. These are expensive, too.
Contact a good tuner and ask direct questions about remapping your car. Even consider contacting Vauxhall UK. They might have a recommendation to make to you. After all, there's a production diesel Astra which uses third party ECU maps and it's sold directly by Vauxhall themselves. In the UK! |
