Is it necisary to tune a car with EFI?
Because i was under the impression that car's with EFI, don't ever need to be tuned because the ECU keeps the car in tune, as it doesnt have a carby to adjust. Because I've just got my car back from getting a few things fixed on it, and It really seems to be starting alot rougher and idling pretty rough, since my head and lifters have been changed. |

There is nothing to tune.

Nothing to tune as such, but plenty to do from a maintenance perspective.
A fuel injection system is exactly that - a system. Takes input variables (takes these at face value), processes the data and outputs variables (fuel injection, spark timing). So really, just need to make sure all sensors (inputs) and injection/ignition (outputs) are working ok.

I reckon the communication between the sensors and the EEC is a bit like chinese whispers.

if they disconnected the battery, this could be the reason for a rough idle, as the computer resets itself. try running it on premium, i notice some cars fire and run better with premium.
