ever since I got a Jeep Wrangler, I pretty much put my RX8 in the garage most of the time, but occasionally, I took her out for a little spin. my Jeep being a 2.5L with only 120hp is no where near as fast as the RX8, but it has a cable throttle body. I've been driving the Jeep lately, but every time I drive my RX8 I notice the small delay between you get on the gas and the engine actually puts out power. on the Jeep there is no delay being a cable system, but on the RX8 its very noticeable.
same happens to my motorcycle. I had a 600RR before, and it had a cable system, and I liked it a lot being very smooth on and off the gas. then I got an R6 which has a drive-by-wire system just like the RX8, the jerkiness between on and off throttle is driving me crazy especially at low speed low gear riding just constantly jumping back and forth. sometimes on the track it would unsettle the bike quite a bit in a corner.
sometimes, I think being more advanced isn't always the best case, especially for high performance machines you want the best driving experiences, but just some small details could ruin the feel a little bit.

 

At least the RX-8 has a proper hydraulic clutch - not some darn cable operated thing. Throttle by wire has become universal I'm afraid and yes thay are laggy but I'd take that over a cable clutch manual tranny any day

 

Try taking your meds ....

 

Should be moved to the Lounge

 

i agree heavily with op. drive by wire throttle is bother some and very slow in reaction...i preferred the cable throttle from the rx-7 better..and far more responsive then the **** the rx-8 has

 

yeah, that half a millisecond lag really pisses me off... grrrrr and stuff. oh wait, no it doesnt.

 

its more than half a millisecond Id say. more like half a second.

 

Half a second? You seriously need to learn how to control your right foot i'm afraid

 

half a second is a bit too much I admit, but its not instant.

 

never noticed any lag - maybe you got a lemon .

 

I got a lime and the throttle is very good and linear, don't notice any lag.

I notice the delay, but it hardly bothers that much. Plus, one of the 7's I owned had a broken throttle cable, so it was rigged to barely work. That made me love my 8's throttle system so much more. Sure, more electronics means more **** to break, but at least it won't stick on WOT until I turn the car off D:

 

i just got an r6 im going to try and pay attention to this

 

Not as much feel, but I am not complaining at all with the drive-by-wire throttle.

At least the RX8 doesnt have DBW brakes like the E55.

 

should look into a throttle controller to customize to your liking blitz makes one and a few others do also

 

I must agree, i'm fairly against taking anything that works perfectly well and overcomplicating it with computers and servos, but the minor lag doesn't bother me much. My other car is an old van with a cable throttle body, but that engine is a bit worn out and delays even more when i step on the gas. I don't think it's so bad. I'm actually not a fan of the brake pedal feel, though. I'm a bigger fan of a harder brake pedal. That's just personal prefference, though.

 

I had no idea the 8's throttle was fly by wire until some time after I got it. Never felt a delay - not even after I learned that's what it had.

There is no delay - it is instantaneous.
The onset of torque in the rotary motor is not, however.
We have the same DBW system as the Mustang. Try that car and then report back about the "delay". lol

The throttle opening angle as it is proportioned to the APP sensor is fully programmable. It is just like changing the bell crank on a carb and just as responsive.

lol

 

hummm, maybe Im an idiot dont know how to drive.

 

More likely that you are mistaking the lack of torque from the engine at low RPMs or high gear loading for a delay in throttle opening angle.

Try driving along in first or second gear at a steady 6500 - 7200 RPM and then tip the throttle in. There will be no delay.

 

I can say my throttle response during competition is if anything, too responsive

Couple of us just discussed this not too long ago

 

after thinking a little I completely agree can drive a high rev engine like others. when I first got my 8 I wanted to shift as if it were a piston engine and I was annoyed byt he lack of power or response. shift at higher revs you wont see the same lag

 

Improved throttle response is listed as one of the improvements in the Series II. I've never driven a Series I RX-8, but I can say that Mazda has the throttle programmed pretty damn quick on my 2009 Series II. I love it. It's the fastest throttle response I've ever experienced. At low RPM, it may not have a lot of pull, but I immediately feel the throttle respond when I touch the gas pedal. It all comes down to programming with e-throttles.

 

i think perhaps the drive by wire has more of a limp pedal feel compared to a standard cable setup..but its a smooth setup and once you get used to it, its not bad at all. i'm still in the old school mindset and stuck in my rx7 ways, so i prefer the cable setup..but i love my 8..so as with any car, there are some tradeoffs.
