I have been offered a re-mapped standard ECU for a GTR.. The ECU was mapped in japan by a company called Saurus?? anyone know anything about these people. The map is done to suit very similar mods to the ones I am running. But I have some doubts it will just plug into my car and run fine? also what about the fact it would have been mapped to suit jap fuel?

Any info welcomed.
Thank you

Lee

OK.. sorry for my stupidness here.. But what exactly is detonation?? I gather it is avoided by retarding the ignition timing?

Thank you but that didn't explain what detonation actually is?! pinking?
pre-ignition? can you hear it or is it only picked up by a special sensor?

In answer to the other bit of your Q: you can quite often hear det if it's reasonably bad. Skeleton's [email protected] in a biscuit tin or shagging a bag of crisps is the best analogy i've heard, though quite where they came from i've no idea.
Always best to use Det cans to hear it though, as it's something the untrained ear can miss.
