does lightened flywheel/driveshaft affect tuning?

[Fenvy]

it is to my understanding that tuning adjust your a/f ratio and input it in whatever a/f management you got

but flywheel/driveshaft seems to affect rpm so I want wondering if I can just get my car tuned, then install flywheel/driveshaft

[Alfador]

I'm not sure what you're asking. Are you asking if you can have the ecu tuned and then later install an aftermarket driveshaft and flywheel? It shouldn't cause a problem since both of those dont really have anything to do with engine operation, just how the power produced gets to the wheels.

[Fenvy]

yes that's exacrly what I'm asking

[180fan]

that stuff won't do anything to the ecu tuning.
