“ACCELX reduced my baseline setup time by roughly 80%. I can now spend practice refining the final details instead of wasting most of it finding a usable starting point.”
Elias S.
Semi-professional club driver
“I had everything working in about three minutes with no engineering experience. Engineering always felt inaccessible before, but Tessie explains the changes in language I can understand and test.”
Priya
ACC community racer
“The first setup it created for Spa was incredible. I completed two full stints looking for something to change and ended up keeping every suggested value.”
danielbuttired
LMU endurance racer
“My profile follows more than lap times. It tracks consistency, braking habits, setup preferences, and the areas where I keep losing time.”
K. Nair
Casual Assetto Corsa driver
“Driver Profiles are brilliant for returning customers. We can immediately see what they previously worked on and continue their coaching without starting from zero.”
Schulz
Sim centre instructor
“I mainly raced iRacing before getting more serious about ACC. ACCELX made the ACC setup process easy and quickly adapted to the way I prefer the car to rotate.”
arjunpls
iRacing regular and ACC driver
“It helped me separate driving mistakes from genuine setup problems. That alone stopped me from constantly changing the car when the real issue was my technique.”
Hana
Track-day regular
“I genuinely cannot race LMU without it now. It detects what I am driving, reads the setup, analyses the session, and gives me a clear plan before the next run.”
n0tLiam
LMU Hypercar driver
“The telemetry traces are detailed but still approachable. I can compare braking, throttle, steering, and speed without needing three different programs.”
Sameer
ACC league driver
“My Driver Profile noticed that I was consistently releasing the brake too quickly. Correcting that gained more time than changing the setup, and the car became easier to place.”
M. Laurent
Semi-professional endurance driver
“I have years of rFactor 2 experience, but LMU setup work still felt awkward. ACCELX made the LMU workflow dramatically faster and easier to understand.”
jamieinnit
rFactor 2 regular and LMU driver
“The personalised advice is far better than downloading a random setup. My profile knows I prefer a responsive front without a nervous rear.”
m1ra
ACC endurance driver
“I gained eight tenths at Imola in one evening. More importantly, the car became predictable enough to repeat the lap over a full stint.”
probablynina
LMU community driver
“Assetto Corsa setup management used to mean folders, notes, and guesswork. ACCELX makes the whole process organised and surprisingly easy.”
Dev
Assetto Corsa league driver
“My unusual setup folder added a few minutes to installation, but the developers responded quickly and helped me fix it. Everything has been effortless since.”
noahh
ACC beginner
“I love how it connects what I feel through the wheel with the telemetry. It makes every setup decision easier to understand and properly evaluate.”
Amara
Track-day enthusiast
“I told Tessie that the rear was snapping during direction changes. The setup it created fixed the problem immediately, and I did not need to alter another value.”
joshbutworse
LMU prototype driver
“Customers understand the feedback because it uses normal language. The adjustable layouts and accessibility options also work extremely well in a public sim centre.”
Zofia
Sim centre coach
“I gained just over a second at Bahrain. Tessie improved the braking balance and traction without making the car feel slow or lazy.”
vikkk
LMU driver
“The advanced telemetry screens took some time to understand, but the standard coaching view is very easy. I needed no engineering background to start, and the recommendations became more personal as my profile developed.”
emliy
LMU beginner
“My Driver Profile is easily one of the most unique features. It remembers how I like the car, recognises recurring habits, and gives me more personal recommendations as I complete more sessions.”
schulzie
LMU league driver
“I knew almost nothing about dampers or aero balance. Five minutes later, I was making sensible changes and understanding what I should feel on track.”
snehaaa
Developing sim racer
“Individual profiles have transformed repeat sessions at our centre. Customers return to their own progress, handling preferences, and previous coaching points.”
Aisha
Sim centre manager
“My Driver Profile makes improvement visible even when I do not set a personal best. I can still see better braking, cleaner throttle use, and stronger consistency.”
Mei
ACC community driver
“Tessie makes engineering accessible without removing the useful detail. I can stay in the simple interface or switch to engineering mode when I want to dig deeper.”
S0PHIE
LMU league driver
“Driver Profiles give me a long-term view of each student. I can see how their technique and consistency are developing across multiple sessions.”
Thabo
Sim racing coach
“I used to avoid setup engineering because it felt like homework. Now it is a quick conversation, a generated setup, and a few focused test laps.”
rahulagain
Assetto Corsa community racer
“Automatic setup versions are brilliant. I can test ideas without overwriting the setup I already trust, and every change stays organised.”
Yusuf
ACC endurance racer
“The app looks serious, but it is incredibly easy to use. I was collecting telemetry and building my profile within minutes, even though I had barely touched setup work before.”
Nadia
Casual sim racer
“Automatic detection and setup writing save our team hours of repetitive work. Preparing a rig for a customer now takes minutes.”
Kwame
Sim centre technician
“I use my profile as a record of my simulator development. It brings together my tendencies, progress, setup preferences, and recurring mistakes.”
L. Bianchi
Club-level track driver
“I saved almost an hour preparing for our last league race. The baseline was so close that I only adjusted tyre pressures for the conditions.”
Farah
ACC endurance racer
“I went from being afraid to touch the setup menu to understanding what the important settings actually do. It made engineering feel welcoming and simple enough to use straight away.”
Shreya
ACC beginner
“Corner events, phase analysis, telemetry channels, Driver Profiles, and confidence indicators give us a complete coaching workflow in one application.”
N. Kim
Sim centre telemetry coach
“It makes engineering easier without pretending there is always one perfect answer. I receive a strong direction, test it, and remain in control of the final setup.”
C. Bennett
Amateur club driver
