Home > THE FRP PROCESS/TECH DATABASE > HPTuners Tuning (96-2020)

HPTuners is kind of an unconventional method of tuning. Rather than using a handheld programmer from which to load tunes to and from, It communicates via the interface (the silver/black box if using an MPVI1 or black/blue box if you're using an MPVI2) communicating directly from laptop to the vehicle's OBD2 Port (located under the dash or steering column) . We also use the interface to datalog so as to refine the tune specific to the vehicle.

There are 2 programs you'll need to download. VCM Editor, and VCM Scanner. Editor is what we'll use to write the tunes to the vehicle, and Scanner's purpose is to datalog. You'll also need to download the drivers which should be included in the VCM Suite. Ryan primarily uses "VCM Beta Suite" so you will want to download the "Beta" version off of hptuners.com

HPTuners just reformatted their website as of June 2018. You will need to 1) make an account on hptuners.com and 2) register your device.


MPVI1/MPVI1 Pro Initial Instructions:

Once downloaded, open up VCM editor . Go to "Help", then "Application Key". The Application Key (henceforth referred to as "App Key") is how the software recognizes the interface. It is the interface's signature. This is used for recognizing the vehicle so we don't have to license it every time we do something with the vehicle. Once it is entered correctly , you can back out of that screen.

Next you'll need to read the tune out of the vehicle. For this you'll need to go out to the vehicle, and with VCM editor open , select "Read Vehicle". You'll need Key On Engine Off for this . Then select "Read" . Follow the prompts as it may require one or more key cycles for a successful read.

Reading the factory tune should take 3-15 minutes or so depending on the vehicle. After the read is complete VCM Editor will automatically prompt you to save the file. Please save this file as it is your original read. Afterwards, send as an attachment via email to ryan@frptuning.com

MPVI2 Initial instructions:

An MPVI2 requires a wifi connection to read/write to vehicle.

Once downloaded, open up VCM editor . Go to "Help", then “MPVI2 Verification Code”. The “MPVI2 Verification Code” is how the software recognizes the interface. It is the interface's signature. This is used for recognizing the vehicle so we don't have to license it every time we do something with the vehicle. Once it is entered correctly , you can back out of that screen.

Next you'll need to read the tune out of the vehicle. For this you'll need to go out to the vehicle, and with VCM editor open , select "Read Vehicle". You'll need Key On Engine Off for this . Then select "Read" . Follow the prompts as it may require one or more key cycles for a successful read.

Reading the factory/current tune should take 3-15 minutes or so depending on the vehicle. After the read is complete VCM Editor will automatically prompt you to save the file. Please save this file as it is your original read. Afterwards, send as an attachment via email to ryan@frptuning.com

General Instructions (not device specific) :

Once Ryan sends a base tune for your application (the original read is needed for this step to happen), you will open it with VCM Editor, and select “Write Vehicle”. Key On, Engine Off needs to happen for the write to happen.

After writing to the vehicle, it’s time to datalog. Open up VCM Scanner, add your device (see in “Help” folder), then once the program recognizes the device, add the channel configuration Ryan has sent (if you don’t have it, just ask) . On the left hand side , under where it says “Channels”, click on the folder icon, and if you go under the Downloads tab on your screen you should see the .XML file . Select that, and it should populate with a series of datalogging channels for which we need to record.

IF YOU ARE HAVING DIFFICULTY GETTING OBD2 CHANNELS TO RECORD (this seems to be most common with 96-2002 vehicles) - click on Vehicle, then “repoll for supported parameters”- to select the channels you need.

Should the config not work, please manually add the following:

96-03 models:

  • Engine rpm

  • Intake manifold absolute pressure

  • Intake air temperature

  • Engine coolant temp

  • Long term fuel trim bank 1 (bank 2 as well if your vehicle has 2 upstream/front O2 sensors)

  • Short term fuel trim bank 1 (bank 2 as well if your vehicle has 2 upstream/front O2 sensors)

  • Wideband (analog input, not a channel per se)


04-Present Day models:

  • Engine rpm

  • Intake manifold absolute pressure

  • Pressure Ratio

  • Aircharge

  • Short term Knock Retard

  • Long Term Knock Retard

  • Throttle position

  • Pedal voltage

  • Intake Air Temperature

  • Engine Coolant Temp

  • Long term fuel trim bank 1 (bank 2 as well if your vehicle has 2 upstream/front O2 sensors)

  • Short term fuel trim bank 1 (bank 2 as well if your vehicle has 2 upstream/front O2 sensors)

  • Wideband


You will also need to select your wideband O2 sensor as an analog input (excluding AEM X series which should show up as a selectable channel once plugged in). To do so, wire in your wideband to the HPtuners device (MPVI2 users will need a Pro Link) , then select the gear icon to add your wideband of choice into the data stream.


After all this is done, you are ready for datalogging!

Select “connect vehicle” then hit the big red button to initiate recording. Hit Stop (blue square) to stop recording. DONT FORGET TO SAVE!

Let the vehicle warm up, then start datalogging and drive it around- no beating on it, just light throttle, keep it below 3000 rpms, etc. A 3-5 minute long log session is enough to start off with.

Your log will be in .HPL file format. Attach to email and send to Ryan@frptuning.com for further review, then schedule a date and time for which to finish tuning.
