Pedal Commander - first impressions - 2.0T

[irtg]

Installed a pedal commander yesterday as accelerator felt laggy, especially in comfort mode - first 20% of pedal input felt very unresponsive.

Wow - what a difference - feels like a sports car now! The driving experience feels like a lot of extra power (I know it doesn't actually increase power). Really enjoyable to drive, instant response from throttle, gear changes are a lot less delayed - and the best bit is it's like driving in sport mode but without the high rev hang - you can accelerate hard in comfort mode, when you lift off the gears change up quickly and don't leave the engine screaming at high RPM.

Loving this mod for such a cheap and simple device. Only took 25 mins to install (15 of those were waiting for the ECU to shut down before plugging it in).

Highly recommended for the 2.0T.

Yeah I have one and love it makes a huge difference. People on here will say it doesn't, but I have a different experience. I'm usually negative three dots on the upper level red. Other wise shifting is too aggressive

This is something other than turbo lag? Because the one difference in the 2.0T and 3.3TT is turbo lag, much more pronounced in the 2.0T. I've always thought this was the difference between the TT and twin scroll turbo. Pedal Commander is saying that the "delay disadvantages" are "electronic gas pedals". So, not turbo lag after all? Talk to me.

I had the K5 turbo lag in that car was terrible in my Stinger 2.5T I can't say I feel any lag.
Maybe the twin injection GDI and MDI compensates for that

Is that different from the 2.0T? I confess, I've never really educated myself on the different engine designations and what those mean mechanically. I thought that the only difference between the 2.0L and 2.5L is the capacity and resulting HP upgrade.

There is actually quite a difference between the Theta 2.0T and Smartstream 2.5T engines - the main differences being the water to air intercooler for the turbo, dual fuel injection (direct and port), hydraulic valve lifters, and a coolant distribution valve to heat up or cool down the engine more rapidly. The power bump also came with a decent fuel economy improvement over the old 2.0T.

The Smartstream 3.5T (which replaced the 3.3T in the Genesis lineup) has the same improvements, but the Stinger never received this upgraded engine for some reason.

Yes this only relates to the pedal sensitivity. Felt like there was a big dead zone and damping effect with stock settings - had to push the pedal pretty far to get any sort of reaction, even to get it to drop a gear.

Was driving my wife's mini and the reaction from just a slight accellerator push was instant. Made the stinger feel really sluggish off the mark unless you floored it. I would say the first 20 - 25% of pedal input did practically nothing. There may be a delay/damping threshold deliberately programmed in to conserve fuel / reduce emissions?

The pedal commander fixes all that and the car now responds quickly to pedal input. Night and day difference for me. Makes comfort mode feel more responsive than sport mode, without the really high revs and rev hang. Sport mode feels even more responsive off the mark.

Before the Pedal Cmdr, I was using sport mode most of the time and manually changing up a gear when I stopped accelerating to avoid the rev hang at high rpms.

Bingo. When you switch between comfort, sport, and eco, it changes the accelerator curve. Sport is much more linear and ramps from 0-100% pretty much how you would expect it to act normally. In comfort the first 25% or so or travel ramps up a little slower. Eco even more so. The idea is to make it easier to conserve gas and make acceleration less jumpy and active.

I don't know the actual curves, I believe someone posted them in the forum at some point.

Thanks guys for the information. So, not turbo lag after all, just a nanny to make the first travel of the go pedal more or less useless. No wonder my wife drives in Sport all the time.

Haha yes I guess so. Worth it for me, feels alive now.
