yeah, it's definitely noticeable if you upshift really quickly and immediately let out the clutch. the lag makes the engine maintain too many revs and can cause fast upshifts to be very harsh

I doubt its circuitry lag - maybe a delay built into the software but not a hardware delay.... these ECU's are very capable.

I notice it as well. If there is a delay, it is programmed for a reason. Electronics are as fast as a cable.

Agreed. Unless this 'alleged' issue is hard coded into the circuitry. I tried this on my car and could not replicate.
