Off idle hesitation

I just traded my 14 M7 Z51 for a new GS a few days ago, and reading this thread I just realized, over the 35,000 miles I put on it I never had it in eco mode more than a few minutes and only then on the open highway.
. It never occurred to me that it could be used on startup or in for city driving.
90% of my driving was happily in sport mode.

This +1 million. I also own one and am simply, utterly amazed at how much it transformed my 2019 Z's driveability with off idle throttle control and precision. Soler Engineering's MTB is THE real deal.

All that this does is increase the speed you travel through the crappy throttle range. You could just as easily press down harder on the pedal. You have to correct the actual problem instead of just moving quickly through it.

Yep, and the only REAL way to do it is through tuning. Ever see a stock z gain .3 on the 60’ and .5 in the 1/4mi with just a tune? It won’t happen with a throttle body but it can with a tune.

I'd be interested to see it on this one. I'm getting tuned plus owning this so my data goes out the window

I'd argue that the only real one is a physical modification, for software is only virtual and depends on hardware. What you are actually doing with tune is removing restrictions and letting the mechanical/physical part unrestricted, freer to act at your command.
Thx,

This topic has been discussed widely. Throttle body physical modifications and tuning are not mutually exclusive, they rather complement each other. Not enemies, but really good friends they ought to be.

i also have a 17 M7, its a little hesitant off-idle sometimes, yes. you kinda learn to drive it just a little more snappy, for lack of a better word. much about this is subjective as it also is gonna depend, no offense, on your footwork. some ppl are just slicker, more snickety with their pedal kung fu. bottom line though its just not all there, while still down low. then theres the thing mentioned by that Fran guy (rpm@youtube) about how the throttle isnt even close to fully open until after 3200 rpm. something like that. so especially from a standing start, youre not getting nearly all of it, not even close, regardless of how far in the pedal is.
anything beyond all this requires your friendly neighborhood mike@soler to help correct. for my part, i'll likely get one then let it relearn on it own and forego a tune. i dont wanna change stuff until my warranty is nearly done, THEN i'll throw on the supercharger and this and this and that. natch, another few hundred bucks for the TB is a no brainer, probly gonna be considered a standard mod someday.

Mike, please check us out. This is what many of us perceive, but not normal by any means. Check this thread:

Then I got the MRC upgrade software and now drive the Grand Sport in Sport Mode to get that nannie threshold, etc and it provides a faster throttle tip-in per the tables below. I now don't need or use the Vitesse as the tip-in is find for me in that Drive Mode. So IF you can solve your perceived throttle problem in Track mode, it's tip-in you may want to change.
However regardless of how fast the throttle opens there is a delay in getting air to start moving through the throttle body. That can be improved with the Mods that Mike@SolarEng provides. Definitely will help.

Hi,
I have a 2017 stingray, base engine with a stick shift. I only have 3k miles on the car, but have noticed it has a off idle hesitation during any light throttle acceleration. It acts like the car is "Cold" and running lean, but it does it all the time even after warm up. In the "Eco mode" it is very rough as it switches from 4 to 8 and I'm wondering if this is normal. I've heard of people with other vehicles ( with automatic transmissions ) that they cannot tell when it switches between 4 and 8 cylinder. Mine is very noticeable. Is this normal?
Thanks,
Mike

I have heard something today that may help get my "Off Idle Hesitation" problem corrected by a dealership and would like to know if I'm understanding this correctly.
The GM Global Connect system is used to look at my automobile's ECM Software, cross match it with my VIN number, uses SPS programing, looks at my current software number and then, if their are any ECM software updates available it can update my ECM with the latest revision..
Is there someone familiar with this? Am I understanding this correctly ?
Thanks,
Mike
