Back in February, we published a blog called “Do I Need a Tune When I Put Parts on My CivicX?” It has been one of our most popular blogs and shared by many of you. For that we thank you. Today, we want to share with you a part 2 of sorts. 

While the above question is single-handedly the most popular tuning question, we get asked many others. In this blog, we share with you the top 5 questions we get when it comes to tuning the Honda CivicX with L15 and AccordX with both the L15 and K20.

1) Do I need a PC to use a tuner?

Yes, a PC is required to set up your tuner. You need to download the appropriate FlashPro or Ktuner device software and then make a USB connection from the device to your desktop/laptop. When you launch the software and connect your tuner device to the computer you will be required to register the device. You need to supply basic info so that your warranty and device register with the maker of said device. You don’t need the device hooked up to the computer all the time but will need to when actively tuning.

2) Do I need to keep the tuner plugged in at all times?

No, you do not need to leave the device plugged in at all times. Once you have successfully flashed a calibration onto your car you may unplug the unit from the OBD II port and store it away. We suggest the glovebox so it's always in reach just in case. You will need the device plugged in for live tuning and data logging. KTuner V2 users will need the unit plugged in to get the real-time data to display on the screen.

3) Is there a tune for my specific mods/car or can I run a regular map? For example, does my intake or tip require a tune?

This question is a bit trickier to answer because of all the variables that exist in regards to the tuning device being used. To best answer this question you must first understand what a calibration/tune is. To know that you need to read this blog now.

The OEM tune file is typically good for about 1-2 basic bolt-ons like a street intake and exhaust. The tunes loaded on your tuning device are base calibrations so they are a “general” tune for a typical car and parts. In most cases, those maps are a fine starting point and you’ll get a nice boost in power along with your first bolt-ons on your way to a custom tune for your specific car. Now it goes without saying that a custom tune will always be the best bet but until you get there, any of the base calibrations on your tuning device are a great place to start.

4) How do I find MAF Scaling for race MAF’S?

Easy. you watch this video below.

5) Do I need 4-bar MAP sensors?

If you are running a W1 or stock turbocharger. Then the short answer is no as neither of those turbos can operate safely beyond ~27psi. If you are rocking or plan to rock a W2 or larger turbocharger and intend to make more than ~27.5psi then you will want to upgrade the sensors so the car can safely and accurately read the new levels of boost.

And just like that, your next 5 questions were answered. I hope you find this useful and encourage you to share it with your friends who are just getting into the tuning game so they can be that much more prepared. If there is another round of questions that you want to be answered leave them in the comments below.
