FAQ
Questions I get most often
Short, direct answers. If yours is not here, ask me.
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. My 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. I 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. My 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 I have given the car a 7-step manual mode, shifted from 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?
My deepest work is on Honda controllers of the Civic 9th-gen and 10th-gen 1.8 family. I have started on Mitsubishi with the 2008 Pajero 3.0 V6, and I am expanding to other manufacturers. If your car is not listed, send me the make, model, year, engine and gearbox and I will tell you honestly where I stand.
How much power does your turbo Civic make?
I do not know yet, and I will not guess in public. The car has not been on a dyno. I publish what I 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 I 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. I do not distribute manufacturer firmware, files derived from it, or customer files. I work on a specific car for its owner.
Do you have a workshop I can visit?
No. Hex and Boost is one engineer, Haris, working by appointment in Lahore. There is no walk-in workshop. Message first on Instagram and the details are arranged from there.
Do you work on cars outside Lahore?
I am based in Lahore. Message me with your location and your car and I 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 me the car, the engine, the gearbox and what you want it to do. I reply to every serious enquiry.
