So without employing someone to decipher the whole thread and not having tweaked a car in the past 10 years. One simple question.
Are these piggyback tuning boxes totally undetectable ?
Great to see the same questions being raised about tuners so many years later . Wonder when I have grandchildren if the same APR vs Revo vs xxx will still be ongoing
I can't see how they can be.
For instance if the boost is increased from say 16PSI to 20PSI, the ECU is surely going to log somewhere that these figures being requested are different????? Likewise if limiters on RPM were raised above manufacturer safe threshold.
Don't know how long it would hold the data for (a fixed time or indefinitely).
Unless tuning companies adapt, it's hard to know what they may offer in years to come as the combustion engine becomes a smaller piece of the car jigsaw. In 20+ years when cars are predominantly electric (guessing) that will be quite a different nugget to crack.
