In comparison to my AE86 GT-S...

So just for curiosity's sake, what would need to be done to go from throttle by wire to mechanical linkage?

EVERYTHING! custom made wire, custom throttle body, custom acceleration pedal, Standalone ECU, & list just goes on and on

Everything is technically in place aside from the actual shielded line and possibly a few sleeve retainers, the issue is with how the computer is going to cope with you making adjustments outside of the predetermined route. For instance, from what I remember of the unintended acceleration trial, the computer will cut the engine when it determines that the throttle body is stuck.

just get lighter wheels and a crank pulley

Hi SuperDave, sorry not meant to sound trolling and please don't straight jump to conclusion trolls (if you mean by trolling is me..)
I have never driven GT86 so I cannot say for sure. English also not my first language so sometime its hard for me to explain what I really mean.

What I'm trying to explain is the response when start to step on the throttle, for example when i drive either my ae86 or my integra when I tap quickly the throttle and the rev will react straight away. However on my Altezza if I tap quickly the rev almost no reaction at all so I have to press and hold for fraction of second before the rev will start to go up. Took me sometime for getting use to this. Even I'm used to it, I still prefer the response from my ae86 and integra.

Yes, I think you get what I mean. the reaction from the time hitting throttle.

ive noticed this too, but on the FRS if i have my foot at least 10% on the throttle then give it more gas or modulate the gas during a drift, the response is pretty immediate

Thank you for the confirmation carbonBLUE, how 'lag' the response from FRS? is it closer to car with fully mechanical wire or closer to Altezza?

On the other end, the gts is slow as dirt. This is slow as snails.

fully mechanical wire will always be better for NA,
as for rotational mass upgrades on my celica

high compression lightweight pistons
7lb flywheel
lightweight pulleys

that thing sang all the way to 9800 rpms almost revved as fast as the lfa does, the flywheel was so light i had to adjust idle to 1000 rpms because it would bog and die if it was set any lower, cams also had a part in that too


still deciding if i want to go all NA with the FRS or turbo, i love NA power so much supercharging is also an option

i dunno, i think and so do many others, that the throttle response is great, if you're talking about getting an immediate kick from the engine, i think that has to do more with torque, but if i press the throttle hard or in any fashion, i get massive revs, i can hit 60 in 2nd gear at 6k rpm when heading on to the freeway by pressing the throttle at like 30%.

With torque I can feel my Altezza has way more torque compared to my Integra, what I'm trying to explain and trying to 'lag' as well get an idea how new 86 rev so I know what to expect. By tapping I mean its not like step and hold on the pedal, its more like 'staccato' in music? its like . instead of _ (hopefully this explain?). I've been driving cars like my other 2 cars (dual carbs or individual throttle bodies) for about 10 years and using manual transmission so I'm so used to that instant response. Don't get me wrong, I don't mean this car is bad car but i really wish new modern cars still has that same throttle response.

[SuperDave]

of course, i agree whole heartedly, but honestly comparing my previous daily driver civic to this car, it's a wonder machine. i have friends that don't like electronically assisted power steering or throttle response like a german vehicles, but it is what it is, and to me it's really responsive and most all other reviewers and people tend to agree that the throttle is electric...

I know exactly what you mean and some cars have a shocking delayed response but the 86 is very quick compared to most of them. I was told the ECU capacity has a lot do with it. A small capacity ECU takes longer to compute the command it needs to make from the throttle pedal position, so there's a longer delay. I had a Corolla for a while and found it hard to drive because the delay was so marked. You could tap the throttle and nothing would happen, then the engine would do a rev! The engine revved during gear changes because it was so far behind what was /had already happened.

Don't let it put you off, it's a tiny delay on the 86 and there are aftermarket throttle pedal units that boost that signal to make it virtually instantaneous. I'm sure there will be one for us too.
