FAQ
Questions we get most often
Short, direct answers. If yours is not here, ask us.
Who does ECU tuning in Lahore at firmware level?
Hex and Boost is based in Lahore and works on engine and gearbox computers at the level of their program code, not only their calibration tables. Our published work covers the Honda Civic 9th gen 1.8, the Honda Civic X 1.8 CVT and the Mitsubishi Pajero 3.0 V6.
What is the difference between a remap and what you do?
A remap changes values in tables the manufacturer made adjustable, such as fuel, ignition timing and limiters. We also write new functions into the controller's program. That allows things a remap cannot do, such as boost control on an ECU that was never designed for a turbo, or paddle shifting on a car that shipped without it.
Can a turbocharged Honda Civic R18 run on its factory ECU?
Yes. Our development car, a 9th-generation Civic 1.8 automatic, runs 13.5 psi on its factory ECU. The firmware was modified to add boost control, a 3-bar pressure sensor, speed-density fuelling, an electronic wastegate and protections that reduce boost on knock or a lean mixture. It still controls the 5-speed automatic.
Can you add paddle shifters to a Honda Civic X CVT?
On the 1.8 CVT we have enabled the 7-step manual mode that exists in the factory software and mapped it to the cruise-control buttons in S mode, with no new hardware. It was driven and recorded in November 2026. The instrument cluster on that trim does not display the gear number.
Which cars do you work on?
Our deepest work is on Honda controllers of the Civic 9th-gen and 10th-gen 1.8 family. We have started on Mitsubishi with the 2008 Pajero 3.0 V6, and we are expanding to other manufacturers. If your car is not listed, send us the make, model, year, engine and gearbox and we will tell you honestly where we stand.
How much power does your turbo Civic make?
We do not know yet, and we will not guess in public. The car has not been on a dyno. We publish what we have measured: boost pressure, mixture and timing from 81 logged drives.
Is it safe to modify the factory ECU like this?
It carries risk, like any engine modification, and we work to control it. Every change is tested off the car before it is flashed, and checked against the previous version so that nothing which worked stops working. Protections are added with the performance, not after it.
Do you sell tune files or share ECU dumps?
No. We do not distribute manufacturer firmware, files derived from it, or customer files. We work on a specific car for its owner.
Do you work on cars outside Lahore?
We are based in Lahore. Message us with your location and your car and we will tell you what is practical.
How do I start?
Send a message on Instagram to @hexandboost with the car, model year, engine, gearbox, any existing modifications and what you want the car to do.
Have a car the usual tools cannot touch?
Tell us the car, the engine, the gearbox and what you want it to do. We reply to every serious enquiry.
