LTG PCM Update

Electronics - PCM Update

This product is for customers that have already purchased our ZZP LTG 1.0 pcm and need a basic file update for their ATS, CTS, or 2.0 Camaro. For example, you changed your injector size, changed cam(s), swapped to a different style MAF, changed gears in transmission, etc.  This simple update only applies to ZZP related file updates.  If you have a custom sheetmetal intake, custom turbo kit, or something similar that requires a lot of custom tuning, there will be additional charges.

PCM updates do not come with tech or tuning support.

  • If you selected "I am sending in my PCM core" ship the core to the address below with a detailed note including your name, order #, and a complete mod list.
  • If you selected "Email me a file" that means you have HPTuners already and then you will email your file along with your complete mod list, order number, and we will modify your file and email it back to you.

Ship PCM cores to:

ATTN: (Enter order #)
2450 28th Street SW
Wyoming, MI 49519

*If you order products along with this, everything will be held until the PCM arrives and is reflashed for shipping.
*If you do not include a detailed note with the PCM it will delay your order.

*If you have a 2016+ car you likely will have to purchase credits to re-license the PCM if choosing sending in core first. If you have any questions about this process or how many you'll have to order please email

If using your own laptop for remote tuning, download the latest stable HPTuners VCM Suite here.

down pipe install

It was pretty straight forward. if you've done the pcm update, you just email your file to Matt if whatever part you've installed requires a tune.

No brainer

Why spend the money on mods without getting them dialed in? These guys will take care of you.
