Remote Tuning 101: Getting Started, Reading & Flashing Tunes, and Data Logging!

At Gwatney Performance, we have always tried to streamline the pain points of modifying your vehicle.  Our goal (seeming ever far reaching) is to simplify this process as much as we can, while offering industry leading support along the way.  

We’ve want to provide a complete solution for our customers – from bolt on, cam / head install packages, forced induction builds, and machine work.  Tuning is a critical step throughout this entire process.  Although some builds will require a dyno (the big forced induction / nitrous builds) – almost everything else can be done remotely with minimal downtime.

We know the majority of our customers don’t have easy access to dyno facilities (and often times even knowledgeable tuners that are willing to stand behind their work).  

We started doing remote tunes years ago, and in the beginning we were able to manage the process to our high standards, but recently – the dramatic increase in volume became an overwhelming task for us (to the point that we actually discontinued the service – as the MANY of you that reached out realized). 

Because there are so many steps in the process (not necessarily hard – just a lot) – we were spending more and more time walking our customers through the Setup & Configuration process, and much less time getting to do the actual tuning.  

We are relaunching our Remote Tuning program today with a Complete Remote Tuning Guide that aims to streamline this setup process.  If you have remote tuning questions – they are probably answered here. From unboxing and setting up your HP Tuners MPVI-2 hardware to Data Logging, we’ve got you covered at every step along the way.  Let’s get started!

Remote Tuning 101: Getting Started

So you’ve ordered your Remote Tune Package from us, and just received your package in the mail that includes your HP Tuners MPVI-2 hardware?  Let’s get started.

Remote Tuning 101: Flashing Tune Files

At this point – you’ve read the stock tune file out of your car, and have emailed it to us.  We will return to you a modified tune file (sometimes called a startup tune).  This tune file is designed to get your vehicle started and running safely – but we still want to make some changes to optimize both performance and drivability.

  • Open VCM Editor (Beta)
  • Select “Open” icon in VCM Editor (first icon in menu bar – looks like folder)
  • Navigate to where you saved the Modified Tune File (“”Documents > HP Tuners > Logs and Tunes”), select the Modified Tune File, and press “Open”
  • Select the “Write Vehicle” icon from the top menu bar of VCM Editor
  • Select / Deselect Required Modules
  • Select “Write”
  • Cycle Ignition Off and then back On

Remote Tuning 101: Data Logging

You’ve made it to the final step of the learning process.  You are basically a remote tuning ninja at his point.  You have now flashed a Modified Tune File into your vehicle, but now we need to gather some data to determine what changes to make to optimize both power and drivability.  We call this the Data Log.

1) Setting up VCM Scanner

  • Open VCM Scanner
  • Download Channel Configuration File
  • Save it to “Documents > HP Tuners > VCM Scanner > Channel Configs” folder
  • Download Dashboard Layout File
  • Save it to “Documents > HP Tuners > VCM Scanner > Layouts”
  • Select “Open Channel Config” and select the Channel Configuration File you just saved here
  • Select “Open Layout” and select Dashboard Layout File you just saved here

  • Turn vehicle ignition to On
    • Vehicles with keys – turn two clicks
    • Vehicles with push button start – hold start button without foot on brake for around 5 seconds – until gauges light up
  • Open VCM Scanner
  • Select “Connect to Vehicle” button (blue car icon in top menu of VCM scanner)
  • Select “Start Scanning” (red record button in top menu of VCM scanner)
  • Start vehicle
  • Drive around for 10-15 minutes of normal driving with a couple of short full throttle pulls, will do more full throttle pulls later when we are comfortable with the tune
  • When complete with 10-15 minute drive, select the “Stop Scanning” button (blue square icon in to menu of VCM Scanner)
  • Turn vehicle off
  • Select “Log File > Save Log File As” and save Log File to “Documents > HP Tuners > VCM Scanner > Logs and Tunes
  • Select “Disconnect from Vehicle”

3) Emailing a Data Log

  • Reply back to the previous email we send with your Modified Tune and attach this Data Log File.
  • List any drivability issues, or concerns you have in the email. 

Remote Tuning 101: What's Next?

That is it!  You’ve done all the hard work.  From this point we will go back and forth with email communication.  We will send you revised Tune Files to flash, and you will send us new Data Logs.

On more simple bolt on setups, we can normally dial in a tune within a few revisions.  On a more complex head / cam setup – it might take 5 or more to get it dialed in perfectly.

An application from a returning customer may be denied, however, if that customer has failed to repay other Affirm loans on time or if the customer shows excessive borrowing behavior.

DOES AFFIRM PERFORM A CREDIT CHECK?


Yes, when you first create an Affirm account, Affirm perform a ‘soft’ credit check to help verify your identity and determine your eligibility for financing. This ‘soft’ credit check will not affect your credit score.

WHY WAS I PROMPTED TO PAY A DOWN PAYMENT WITH A DEBIT CARD?


Affirms tries hard to approve every purchase but sometimes can’t approve the full amount. When this happens, Affirm provides a debit card down payment option so that you may still complete your purchase right away.

WHY WAS I PROMPTED FOR A CHECKING ACCOUNT?


Affirm sometimes requires additional information to consider a credit application. Such information may include an active checking account, which helps Affirm verify your identity and your ability to repay the requested loan. If they prompt you for this information but you are unable to provide it, Affirm will be unable to approve your credit application.
