By this I mean are all fuel, boost and timing maps overwritten completely with the factory tune stored when you first perform a flash tune.The reason I ask is I am getting some pinging at high RPM which I am investigating, but assumed it would be resolved by going back to the factory tune - thinking it was just too much boost/too hot/too much timing or something. I never had any pinging on the stock tune before flashing the car. However, it now pings even after reverting to the factory tune.I am not looking to diagnose the pinging (I have a different thread for that and am changing plugs, fuel filter this weekend to see if that helps). I am just wondering if flashing it back to stock does a complete job or whether it possibly leaves some of the data in there that was altered by the flash tune, which would explain why the car could possibly be pinging even after running the stock tune again. I am guessing this is probably not the case and I need to be looking at other things as I am (fuel filter, fuel pump, plugs, coil packs etc.)Car in question is a BF2 TAdam Link to comment Share on other sites More sharing options...

A counter saying how many times it has been flashed doesn't say much - I didn't buy the car from the local dealer. The dealer I bought it from may have reflashed it with updates a few times.

adamw Member 143 Member For: 20y 5m 30d Location: Darwin Posted 04/03/08 05:31 AM Author Share Posted 04/03/08 05:31 AM I think any reputable tuner would be able to see that data, and since it is alterable (I.e. it is logging what has changed), the tuner would also be able to alter it to remove that.Would be interesting to know for sure - its the sort of thing lots of myths are likely to come out of.Either way it pings on the factory tune with no mods - I don't think it is unreasonable that they try and diagnose it.

adamw Member 143 Member For: 20y 5m 30d Location: Darwin Posted 04/03/08 05:37 AM Author Share Posted 04/03/08 05:37 AM I know what the F slot holds.. it holds the factory tune, downloaded the first time you reflash the car using one of the tunes on the box.What I'm saying is, the data that is held in the F slot.. is it complete? I.e. When you reflash the car with say, an 8psi tune, and then revert back to the factory tune (by reflashing the car from the F slot), does it completely overwrite everything in the ECU that the 8psi tune changed?
