I recently had a full freeflow system fitted to my Opel/Vauxhall Astra Turbo Coupe. Along with this, I had a stage 1 STO map done to take full advantage of the new exhaust characteristics. At any rate, I asked the tuner whether I could use the Torque Pro app I had on my Galaxy Tab to read boost, temperature, timing advance, etc from the OBD port like I did before. He said that attempting this would corrupt the map. He also stated that the STO software he flashed to the ECM would report false readings.
Now, I know the answer is reasonably obvious to someone who is a software developer and knows a bit about the OBD protocol, but rather safe than sorry. It seems the guy thinks I want to reverse-engineer his map and sell it or customise it even further, so talking to him is like talking to a brick wall.
- Is it possible to make the STO software (or any software loaded onto OEM ECU's) report false readings on the OBD port?
- Can the STO software (or other software) be used to trash a map if it detects communication on the OBD port?
I never had issues with reading stuff from the OBD port when the car was still standard.
