Getting started with HP Tuners Editor and Scanner
Read your stock existing tune and save it to downloads. Label the stock read as "your name stock read". Do NOT read the FPCM, the last box — check that as "Do Not Read" or it will cost 2 more credits.
We will supply the LFX scan config file to use. Click "Load config" on the far left and pick where the file saved, usually in Downloads, then do a 5-10 minute drive and save it as "your name here Stock Drive Log". Do not click on it directly.
Then email us both files and we will go from there. Download VCM Suite from hptuners.com/downloads.
Once we study the scan we will adjust the parameters in your tune file and send a new revision back to you to flash in, then you do another drive log and email it back to us. It usually takes 2-3 rounds to get your individual car dialed in.
