Part 3: The Quest for the Perfect Tune

[69Mach390]

I am not sure that one is timed right. I mean it shows valid on the dragy but we've never had any other 4s hit 10 seconds.

BTW keep in mind if you are driving 30-45 in the city then consider stock quartermile to be over 12 seconds as you can't use launch control.

Just wanted to follow up on this. Took my 2024 4S tuned to the drag strip tonight. 21” RS spyder wheels.

10.99 @ 128 mph. 96% charge and 80 degrees out. Very happy. Raced and Ioniq 5N. He did 11.1 at 121 mph.

10's is very nice for a J1.1 4S.

“For the first time, the Manthey Kit also includes adjustments to the powertrain: optimisations to the high-voltage battery, control unit and pulse inverters increase the maximum discharge current while driving from 1,100 to 1,300 amps.”

Wondering if they gimped the power of the Turbo GT from the factory so they can sell their kit with “full power”.

Note "while driving"...
They just upped the power in attack mode and base power. The LC power remains the same 860kW afaik.

For sure. Looks like my numbers are almost identical to a J1.1 turbo, but the trap speed means neither the turbo nor turbo S would want to race without launch control.

I ran 2 more runs, both 11.0. Highest trap speed was 129.

What is a trap speed?

Amazing numbers for 4s!! Tuned turbo can do 10.5? Anyone with some real numbers?

What is a trap speed?

The speed at the end of the 1/4 mile. Usually it lines directly up with how much horsepower a car makes and is an indicator of how fast it will be in a rolling race.

For example- the Ioniq 5N I raced was only 2/10th slower but going 8 mph slower by the 1/4 mile.

He launched harder and beat me to 60, but above 100 mph I was significantly faster.

His trap speed and mine were both 101 mph at the 1/8th mile mark. But by the 1/4 mile I was doing 128-129 vs him at 120.

crazy how fast the Ioniq 5N is.

I just installed the MapEV ASG on my new to me CPO 2022 4CT and could not be happier!

I am coming from a 2022 Model S Long Range and before the ASG swap, the 4CT felt slow. Even when engaging launch control, the car was slow. Even worse when launch control was not engaged. The plan, even before I bought the car, was to get the MapEV ASG as soon as I bough the car.

Here are a few before and after Draggy slips. All Same day, same place and roughly same SOC (about 50%):
- 3.72 is post-install, from a dig, no launch control
- 5.57 is pre-install, from a dig, no launch control
- 4.61 is pre-install, from a dig, with launch control

Hoping to see sub 3.5 with cooler weather and higher SOC, but overall the car feels great!

Now try with launch control with the tune, it should be slightly faster still.

Tried again yesterday with launch control and got it under 3.5:

Hi, just wanted to ask for the fast-ASG-changing-parts? Is there hope to get it? I would be very intrested to tune my 2024 CT4 BP+
thanks for Information, kr Gü, Austria

Summer happened, so not much getting done, I'll update here if there are any news.
