I haven't made any changes to my car. Those parameters are the default when using Simulation mode in XENTRY. Simulation mode lets you explore and learn many of the functions in XENTRY. However, it's not perfect and can be frustrating.

Tks! It could be just simulation mode of Xentry playing tricks in this case. My E400 has this parameter set from the factory at 2. I'm trying to understand what it actually does.

Launch creader x431 mercedes. The horizontal screen one is what I have. After more driving I will say there are still scenarios where there is a long lag getting back on the throttle after nearly stopping but certain scenarios are definitely improved. Basically it's recommended but won't fix all scenarios.
I have the Launch CreaderX431so am I able to change the throttle setting please? I saw another post of yours in which you mentioned BenzNinja coded out your throttle lag - I have a 2017 C43 and find the throttle alternatives between crisp and spongey which drives me nuts….

This is not uncommon, my stock 2014 M276 3.5-NA was getting increasingly heavy with slow-poke driveability.
I don't know much... here to learn about you guys experimental throttle response coding.
> HELP & OPINIONS ....
The good news is *ALL* THROTTLE-BY-WIRE engines response are computed based on maps learned from historical combustions. That's nearly every engine since 2000, here including MB M276 TT/NA.
Can you confirm your LTFT numbers at warm idle are LEAN below -10% ??
