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 Alan.M@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.

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.

I had a wonderful experience with the original tune. Bumped my ss manual psi to 25 from stock. But that wasn't enough. I replaced all my stock exhaust with zzp parts. Still not enough, I replaced my charge pipes, and intake, added a bov, which required me to relocate the maf to a charge pipe and block off the bov. I needed a retune and zzp was quick about it. I only have one problem now, the clutch slips, too much power. I'll deal with it later. For now the retune functions perfect. If I had one tip, replace all the parts you think you'll want to. If you're short on money, save up and stock all parts needed. Do it all at once. They (zzp) don't take long to tune and send back. The cost is only 60 for retune but you'll still have to pay shipping to and from. It'll save you about 150 bucks to do it all at once. But customer service was amazing.

Cobalt ss m62 remote tune

With only one base file and one revision my car runs amazing. Ran so awesome off of my remote tune i went to the local track the next week and set a all new 1/4 mile record for a m62 ecotec at a 12.07 @ 115.92mph. That result Speaks for itself thanks zzp

Hpt update

Getting a pcm update is absolutely amazing with Matt. I'd email him at 4 in the afternoon and he had the new tune ready by 930am the next day. And the car runs amazing
