This product is for customers that have already purchased our ZZP 1.0 pcm for your LSJ, LNF, LHU, or 2.2/2.4 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 LSJTuning@ZZPerformance.com (for LSJ) and Matt@ZZPerformance.com (for LNF, LHU, and 2.2/2.4) your file along with your complete mod list, order number, and we will modify your file and email it back to you.
