Throttle Pedal Lag

12GoFast · 08-22-2021, 06:26 PM

My question is, has GM corrected the Pedal Lag in the later Camaros? I recently acquired a 2019 Silverado with the 6.2L and the pedal is super sensitive, to the point have to watch when pulling out that it doesn't go into tire spin. I have read about the throttle controler, but to me it is just a crutch feeding the computer misinformation. JMO

At least my 2016, the tip in is slow to the point where a throttle controller changes that to be more sensitive. I bought a Solar to solve the pedal lag, but that sounds like the opposite of what you have for your Silverady. I put my TC on SP 5, and it is very "sporty" now. Much to my liking.

2020 LT1 here. I installed the Solar throttle controller to make mine quicker. So I'd say yes they did fix it for what you might like. At least on the camaro's. The Solar is a nice product for the price. It can be fine tuned to what you like easily.

I installed a throttle controller in my 2019 2ss no lag any more….

That sounds like an unusual problem. If your truck is still under warranty then I would take it to a dealer to have it checked.

This is a topic that is commonly approached like this - that it's a "problem." It isn't. This is purposeful tuning.

The LT1 motor is capable of significantly more than it rolls off of the line with. That has been proven time and again from all of the folks that do bolt-on's and tune. When the mapping is developed for the engine, MANY factors are taken into account. And the engine is tuned to be "responsive and power enough" while also adhering to emissions standards and ensuring that GM can provide a solid powertrain warranty as well.

Little things like differences is actual octane of a fuel, whether or not there might be moisture in the gas, a plug misfire, and about a thousand other variables are all taken into account and are part of the equation. If you're racing the car, you care about the off-the-line response and can tune to remove it because you're modifying the car anyhow. Otherwise, it really isn't an issue.

Fully track what you're saying, everyone understands this is done purposefully by GM. Why people think its an issue is because it definitely feels off and really odd. At least in the 6spds, it is abrupt and very jarring if you aren't ready for it.

I've had several friends, who also drive manuals for their daily, stall out not expecting such a sudden throttle dead zone.

I've stalled the car a couple of times in Tour. Never in Sport or Track because the fuel mapping and response is different. So, I understand that the feel is somewhat unexpected sometimes.

OTOH... Give it some gas and go. As long as you get the clutch out quick and don't over-rev when you do, the car will take it fine.

I'll agree with you about track mode, to me though sport has the same poor response as tour mode. If I could get sport mode to have the response of track I'd be happy. Having to click down to track everytime I get in the car gets old, same as Rev match.

Your car is no different. The lag off of the line is there because of how the drive-by-wire programming is done.

The Soler can add lag to the pedal as well. They call it “economy” mode and it does take a fair bit away so you aren’t drinking as much gas from jackrabbit starts.

It was 10 times better in my 2021 LT1 than my 2019 C7 Vette. I felt there was no need for a ported TB in the Camaro.

Wasn't the OP talking of TO MUCH throttles response in his truck? A throttle could tone that down for him I would think.

As far as a LT1 m6 goes I have found it easier to take off without stalling using an eco setting (slower throttle response). I think it because it feels more like my other manual cars. Other than the take off part I prefer the feel of the higher settings. I'm only at 4000 miles so I'm still learning the feel of it.
