Frequently Asked Questions About CHKSuite
Everything you need to know about ECU checksum correction with CHKSuite.
What is CHKSuite?
CHKSuite is a standalone Windows application for correcting ECU checksums after map modifications. When you change any map data in an ECU binary (Stage 1, DPF off, EGR delete, DTC removal, etc.), the internal checksum becomes invalid. Flashing a file with a broken checksum can cause non-start conditions, immobiliser errors, or ECU malfunctions. CHKSuite automatically detects the ECU type and applies the correct checksum algorithm to ensure your modified file is safe to flash.
Which ECUs does CHKSuite support?
CHKSuite supports 500+ ECU types across Bosch (EDC15, EDC16, EDC17, MD1, MG1, ME7, MED9, MED17, MEVD17), Continental/Siemens (Simos, SID, SIM2K, MSD, MSV), Delphi (DCM, MT series), ACDelco, Marelli (MJD, IAW), Denso, Valeo, Visteon, Hitachi, Keihin, Kefico, Ford EEC, Motorola, Temic gearbox controllers, and more. New ECU types are added regularly with software updates.
Is this a one-time purchase or subscription?
One-time purchase of £99.99. No subscriptions, no tokens, no per-file fees. Use it on unlimited files indefinitely. Your purchase includes 1 year of free updates with new ECU protocols. After 12 months, the software continues to work forever on all existing protocols. Optional renewal at £40/year gives you access to newly added ECU types only.
Do I need internet to use CHKSuite?
Only for the initial license activation. After activation, CHKSuite works entirely offline. No cloud processing, no server dependency. Your ECU files never leave your computer.
Does CHKSuite work with my flash tool?
Yes. CHKSuite works with binary dumps from any flash tool including Kess, KTAG, PCMFlash, CMD, Flex, BFlash, MMCFlash, and others. As long as your tool produces a standard binary file, CHKSuite can correct it.
What happens if my ECU type is not supported?
Contact our support team with your ECU details. We regularly add new ECU types based on customer requests. If your ECU uses a standard checksum algorithm, we can often add support within a short timeframe. Support is available 24/7 in 7 languages.
Can I use CHKSuite on multiple computers?
Your license is tied to one device. If you change your computer, contact support for a license transfer. The process is quick and free. We understand that hardware changes happen.
What is the difference between CHKSuite and online checksum services?
Online services charge per file (typically £1–5 each) and require you to upload ECU binaries to third-party servers. CHKSuite is a one-time purchase with unlimited corrections, works entirely offline, and your files never leave your machine. For a workshop processing 20+ files per month, CHKSuite pays for itself within weeks.
