Sounds like you've reset the tune by removing your battery. Keep driving it, it'll sort itself eventually.

what?

what?

An ecu will "self tune" to a point, using the sensors the vehicle has. It will be loaded with a base tune, and if the ecu thinks it can get more power, or it can improve the efficiency of the engine, it will tune itself. Removing the battery resets it to the standard factory tune, and it will self learn again, eventually. It's not often noticeable, but if old mate had something seriously wrong, the self tune could have masked it.

I had a mate with a vz ss, who said his car was down on power and the idle wasn't as "lumpy" as he remembered it to be. We let the ecu reset by removing the battery and she all came sweet. Back to angry LS idle.

Just repeating what a lecturer taught me.

Lol.. old Nissan ECUs are very basic, the only "tuning" it can do is closed loop feedback on the narrowband and even that's primitive unlike WRX ECU which uses the factory wideband to trim fuel

Unlike EVO ECUs and even they don't "self tune", but run multiple maps one for low octane and high, naturally moving from high to low on knock.

Ah yeah. Disregard my previous posts then. Obviously VZ is 2008ish so newer ecu. Cheers for the feedback though.
