3800 PCM Update Service

The ZZPerformance 3800 PCM Update is designed for owners of the ZZP 3800 1.0 PCM who need to adjust their tune for recent modifications. This service accommodates changes such as different injector sizes, camshaft swaps, alterations to the MAF sensor, or modifications to the transmission gearing. This update service is exclusively for ZZP-related file adjustments. For custom tuning requirements, such as those for custom sheetmetal intakes or turbo kits, additional charges will apply. Turbo tuning is exclusively handled via .hpt email files. It is important to note that PCM updates do not include technical or tuning support. If you opt for the "Email me a file" service, you must already possess HPTuners software. You will need to email Bo.C@ZZPerformance.com with your current HPT file, a detailed list of your modifications, and your order number. ZZPerformance will then modify your file and email it back to you. If you choose to send in your PCM core, ensure it is accompanied by a detailed note including your name, order number, and a complete mod list. If products are ordered alongside this PCM update, all items will be held until the PCM is reflashed and ready for shipping. Delays may occur if a detailed note is not included with the PCM.
