Hi all. I have a strong suspicion that the programming for our
cars is purposely tuned to make the rev gain slow when you
put on the gas with the clutch in. When I am heel-and-toeing
for a down-shift, it seems like I have to mash the gas pedal
down a lot, and then wait a long time for the motor to spin
up and match revs, as if the flywheel were from a tractor...
Is there a way to get a really quick motor response for a
faster downshift?
thanks

It's largely due to the fact that you have a Turbo engine. All turbos spool up slower relative to their NA counterparts.

Dock says that putting the Europipe Stage II exhaust helped his rev more freely.

lightweight flywheel

Thanks. Yes, I just realized that this may be just the
worst-case scenario for turbo lag...

SteveH is right. Change to a lightweight flywheel makes a world of difference. Just try one that has it and compare for yourself.

if you have a chance to drive the CGT you really notice with the heel toe that the slightest blip and the tach practically red lines. The only problem with the lightweight fly is that you have to drop the engine to do it and that equals $ outlay.

The light weight fly wheel would help but I believe our cars are also programmed to cut fuel quickly when the throttle is released, this is one of the reasons cars with the lightened fly wheel used to have tendency to stall as I understand it. Perhaps one of the programmers could tell us more? It used to take a special program mod I believe in the pre OBD II cars.

James - how true. Therefore it becomes much more economically viable to do a few other 'under the hood' mods while the engine's dropped. Just think about how much money you will be saving!

Part on it may be the time delay in the egas.
