370z has fancy rev-matching. I'm not a fan...

I wonder if the perception of lag or a need for a more aggressive or sustained blipping action is due to the throttle pedal dead zone. I know it was causing me to screw up downshifts when I first got the car, especially coming from an old-school Miata cable throttle. Other people have also commented on it when driving the car for the first time. I has assumed it was par for the course with a throttle-by-wire system, but apparently it's pretty bad in our cars.

It's pretty bad, yes. My 08 STI didn't have nearly as much lag. Actually, I can't even recall having this sort of complaint about the STI.

How heavy is the OEM flywheel?

Interesting. So, in otherwords, and I'm just throwing out random numbers here, my 1 second "blip", in reality, is only registering on the accelerator for .5 seconds? If that's the case, along with the other factors already mentioned, I'd say that's gotta be it!

Compared to my old e30, the frs is a dream to rev match in. To get the same amount of revs as the frs I would either have to floor the pedal or blip twice.

Yup, the revs fall quickly. Light flywheel to blame?

This car does not have a light flywheel by any stretch of the imagination. It's been weighed at over 20lbs. Don't recall the weight off the top of my head, but it's posted somewhere here.

Agree on this. The first ~3 mm of throttle pedal does nothing. May not sound like a lot, but it is for some drivers (including myself).

Electronic throttle :(

Disagree completely with the deadzone theory. My truck has some slack in the cable and I can feel it, I can also feel the play in the FRS pedal, there is a noticeable delay in the FRS from when I am engaging the throttle pedal (after the deadzone) and when the engine actually responds compared to my 20 year old pickup truck.

Come to think of it, it might not necessarily be the electronic throttle, it may have to do with the ECU switching over to "compressor" mode for fuel savings but it's definitely an electrical choice by Toyota.

But what the hell do I know.

Dual-mass flywheel? I noticed my 318is is sluggish to rev, too. Can't wait to swap out for a single mass.

Electronic throttle, pedal deadzone, and throttle tip-in tables are all to blame here methinks.

Omg how many cars do you have man?!

I've found blipping on the car to be much easier using a throttle controller. Consequently the car is more touchy in traffic, so find one thats easy to turn off and on until someone has a tune that adjusts on the fly to our tastes (lower speeds less jumpy throttle, higher speeds decellerating, more sensitive).
