So I have a tune for a 21 l5p that I did for a friend, I have a 18 l5p. Curious what I need to do other than buy the credits to flash the tune to my pickup. I?m not interested in having someone else edit it unless absolutely necessary. Thanks fellas.
Someone in a different thread informed me the os is going to be different is there someone who has any idea on how to edit the stock tune I currently have? Or interested in trading tunes? This stuff would be awesome if it was open source. I have some ppei tunes for my lb7 and a single 90hp for a l5p.
Yes the OS will be different and therefore not recommended to ram that file into your truck. You will need a file created based on your OS to make sure everything operates correctly.
What’s all required to access the parameters to tune the file myself, I have the unlock tool and mpvi3. What else would I need in order to disable speed limiter and other fun stuff.
Once unlocked you can tune away once license your truck. But there are tuning maps for daysssssssss you can play with on those files.

Comms issue check continuity/load test the circuit, check pin tension. I?ve seen them slip out of the retainer.
All the parameters you need to tune the truck are defined in HPTuners.Originally Posted by Mtxcaleb

What changes to the stock tune were made? If purchased tune, i'd call them any reputable tuner will work with you.
