Throttle Pedal Delay Solved

My nephew just bought a full size pickup with those BIG tires on it. This truck will tear the tires of of itself in a heartbeat.

it is a stock 5.3 engine. when you hit the gas there is NO lag in response! What a difference, it lights up 35” tires right now!

the trick is it has a programmable upgrade called pedal-commander. Www.pedalcommander.com. Appears easy to install and will take you back to your youth. It is integrated into the gas pedal at home in your garage.

look it up and check it out. This thing takes throttle response to a whole new level !

This product is a good option for those who have not had their R tuned or don't want too.

Throttle delay is removed on my R. It was removed as part of "Tune".

My tune, 32hp more, 3 more mpg, drop throttle delay, fan setting change to prevent overheat, firm transmission shift.

Had tune done in 2006 and "retune" every five years or so. That was 140,000 miles ago, my 04 had 8,000 miles when I bought it. That was 15 years ago!

There is no real delay in throttle movement on the SSR. What you are actually feeling is a slow “tip-in” of the throttle. This “Torque Management” is controlled by the computer to guard against aggressive torque spikes in the drive line that can damage the transmission. This is because we have really wide rear tires and 5,000 pounds of vehicle weight. The software is also in place to prevent detonation possibility. The key data inputs used in controlling throttle movement are: inlet air temp, engine rpm, vehicle speed, manifold pressure, engine temperature and transmission gear.

Competent engine tuners will improve the throttle movement with the trade-off of richening the mixture during tip-in. GM doesn’t like to do this, because of emissions, but we understand that it is because they are held to tight EPA limits.

GM addressed the main driver of slow tip-in with the 2005 SSR air cleaner change. The foam seal around the air cleaner is specifically designed to eliminate ingestion of the 160-200 degree air in the engine compartment when you are at a stoplight. This is felt at the inlet air temp sensor and drives the computer into a retarded ignition condition and slower tip-in. On a hot day in Phoenix, a hard launch from a stoplight will finally have full throttle someplace about the middle of the intersection......

Not being negative...... just cautious.

Regards,

Mike

Thank you for clarifying Mike. I was hoping to hear from you on this. Maybe I should warn my nephew to keep away from the higher setting. The trck he bought is a Silverado with a 5.3. It was last owned by Jon Bonjovi.
it appears That. All the upgrades are professionally installed. Included in the many many upgrades is this pedal commander. She really hauls groceries when you hit it in the highest setting. I can’t believe the power applied to the wheels.
ill ask him to be careful.

I find this topic very interesting as I had this problem in spades with my old street rod. My '39 Chevy last engine swap was to a '97 LT-1 with the 4L60 trans. When I would stomp the gas pedal, It would seem that if you counted to 3 fairly quickly, you would be at 3 before anything happened.:oops:

Never realized this was something that could be adjusted and/or eliminated.:(

Well, your reply brings back some scary moments. First of all, I don't think my '97 LT-1 setup in my street rod was what you would term (fly by wire). There was indeed a direct connection from the gas pedal to the linkage atop the motor going to the opening of the whateveryyou call it.........top front of engine.

Here is the scary story that relates to that........Took a trip south on Rt. 31 near Myrtle Beach and didn't notice anything out of order. On the return trip going north on Rt. 31, (I guess because of prevailing wind directions), my hood started to rise up on the driver side. The only way that could happen on a '39 Chevy hood, is because the handle latch did not get closed to hold down that side.

So half way up Rt 31, I pulled to the side of the road and got out and latched the left hand hood side. As I got back in the car, I glanced back down the road and there was oncoming traffic maybe about 1/2 mile away. So i jumped back in and cranked it and figured if floored it, I could stay ahead of the on rushing traffic.

So........I stomped the gas pedal and indeed saw a few cars closing in on me........but my acceleration soon caused me to start pulling away. Thus, I took my foot off of the throttle only to find that (that had NO EFFECT):oops:

So, i'm now going up Rt. 31 at over 85 MPH and growing in speed. So...........I switched off the ignition. While this killed the speed, it also (locked up) the steering column so I couldn't steer away from an upcoming slight curve in Rt. 31.

So, I eased the switch just enough to regain steering ability and was able to steer over to the side of the road again

Popping the hood, showed me that the throttle linkage was (snagged) by a mini "set screw" that held on the custom air cleaner on the front of the engine. it seems the last time i removed that filter (held in place by a set screw on each side), I forgot to screw down those set screws and the drivers side on stuck out just enough to capture my throttle linkage upon a "full stomp" of the gas pedal.

Sounds like you handled a scary moment well. I lost my brakes once. Slightly pulling on the brake always sends 1 of the rear tires into a squeal.
Another time I took a 318 out of my 66 dodge coronet and replaced it with a 440cu. I was on a remote road and thought how cool would it be to burn tire on that wooden bridge over there? Well, I’ll tell,ya how cool,it was, I completely broke the motor mount on the torque side of the motor during the burnout. The motor nearly flipped on its side breaking the transmission mount as well. This also caused the throttle to stick. Like you I shut off the key, got out my bumper jack and managed to pry the engine close to where it should have been. Once back in the drivers seat she started up ok, but when I put it in great the engine would flip on its side and hit the hood! Long story short, I had to drive the car backwards nearly 8 miles back to the house and replace the motor mount on the torque side of the engine. I also put a chain on that side “just in case”. When I sold the car, it still had the dented hood on it!
Lots of funny looks as I drove home backwards! I was getting pretty good at it by the end of the trek. I laugh at myself every time I think of it.

Stupidly, I also had to do the backup trick one time for about a half mile to get back to my house. Earlier in the day, I came home with my pickup and decided that I wanted to check the oil. So, I popped the hood release and got out and raised the hood.
Then I thought to myself, I want a really accurate read on that oil level, so I'm gonna let in drain down and sit for a while and then I'll come out and check the level. So with that thought, I lowered the hood down but not enough to engage the safety latch.

Of course, hours later I came out needing to go somewhere and jumped in the truck. Got out of my subdivision and was gaining speed on the main road when BAM, the hood flew wide open and jammed itself in that position.:eek:

So my reverse trip got me back home where luckily, I was able to pop the hood back down without any hinge damage nor bent sheet metal at the hood corners.:(

I put a peddle commander on my 15 Ram 1500. Made a big difference in the lag. The high setting is almost undeliverable. I keep it set up on the 3rd setting and now it's just right.

My 1932 Plymouth, 4 door, 4 cylinder had "Floating Power" was Chrysler production. They mounted engine and transmission on "rubber" to create "Floating Power"

It worked until the rubber started to crumble from age, (like me). 22yrs old when I bought it for $120 bucks.

My 4 cylinder (32hp) with "down draft carburetor" would crank and "hit" both sides of the hood until it started.

I removed hood, put 2X4 between engine and fender to keep engine from hitting fender when starting or accelerating.

Doors opened away from each other. Handles were close together. Called "Suicide Doors".

Regular gas, no PS, PB, ABS, Automatic, Power Windows.

No such part is available for a Chevrolet SSR. I have Diablo preditor tuner. No problem getting going
