3800 PCM Update

Electronics - PCM Update

This product is for customers that have already purchased our ZZP 3800 1.0 pcm and need a basic file update.  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 using your own laptop for remote tuning, download the latest stable HPTuners VCM Suite here.

Really ties the car together!

Biggest performance increase since reducing the pulley size, and your engine really shows it's appreciation once everything is working in sync, especially with E85! Highly Recommended!

PCM update went smoothly. I already owned the HP Tuners interface and the update was delivered promptly by Tim. I appreciate the prompt service of ZZPerformance staff.
