Got there before me lolIt would run fine.
If you fit a decat (or certain types of sports cat) you will get the engine warning light.
You can turn this off by:
Disconnecting battery for 10 minutes.
Removing KAM fuse for 10 minutes.
Fitting a lambda spacer.
Running wise, you don't need a remap though.
However, I would disconnect the battery overnight so it can adjust and relearn (the ECU) to your new setup.
Sorry but I beg to differ. Yes our ECU is clever but it is NOT that clever. If what your saying is true then nobody should be running any tune other than the stock one and we could have every hardware mod ever developed for the ST and the ECU would just learn to adapt?Not true for the ST.
Other cars you do need to remap to suit each mod, but the ST has a clever ECU.
