Strategy. That’s Why.
Modern cars are complex. Your diagnostic process shouldn’t be a guessing game. DiagFlow gives every tech the same systematic approach.
📋 13-Step Workflow
Systematic diagnostic process from vehicle entry to final verification. Never skip a step, never miss a clue.
📊 Scope & Pinpoint
Built-in scope waveform library with known-good references. Relative compression, VE, cam/crank, in-cylinder, CAN bus — all right there.
🧠AI — When You’ve Earned It
AI diagnostics unlocked only after you’ve done the homework. No silver bullets. Garbage in, garbage out — so we make sure the data goes in first.
🔗 DVI/CMS Integration
Reports flow right into your shop management system. No double entry, no lost data. Currently in Alpha with more integrations coming.
🆘 Get Help
Built-in support request system. Tech completes the workflow steps first — so when help arrives, they’re not starting from scratch.
🔧 Parts Request
Techs can request parts needed to complete the job — right from the workflow. Just communicate what’s needed, keep the job moving.

Scope & Pinpoint
At times, the most valuable tool you’ll use in diagnostics. Our built-in scope library gives you known-good waveforms to compare against — so you know what right looks like.
- ✦ Baseline Testing (Relative Compression, VE)
- ✦ Cam/Crank Correlation
- ✦ In-Cylinder Analysis
- ✦ CAN Bus Communication
- ✦ Amp Probe & Misc Testing
