  • In stock, ready to ship

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 Bo.C@ZZPerformance.com 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.

3800 PCM Review

0-40 with my 99 Lesabre with 2.86 axle ratio and original GM updated flash took 5..1 seconds. Avg mileage was about 26 mpg. After I installed ZZ's flash, 0-40 time was 4.5 seconds and mileage was just over 27. Shift firmness and throttle response is much improved. Both tests were with 87 octane gas and mostly highway driving.

Remote tune, awesome service!

Tim from ZZP handled my PCM update. We exchanged multiple scan and tune files to get it right. Next day response with tune updates, flash and send in a scan file. It was that easy!
