What you get

The detail you need before the car is on the ramp

Not a history check. The working information for the job in front of you — from one plate, in about four seconds.

🔌

ECU, location, and how to read it

Which ECU is fitted, what type, where it sits on the vehicle, and whether it has to come out and be opened. Then the tools that will read and write it — each with its method, and whether the job is OBD, boot or bench.

📈

Stage 1 figures

Stock and tuned power and torque for that exact engine, with the gain in percent — so you can quote before you commit.

BHP stock → tunedNm stock → tuned

Fuse boxes

Every box on the vehicle, drawn and interactive. Hover a fuse to identify it, search by circuit, rotate the layout to match how you're looking at it.

🔒

What we hold — and what we don't

You get the working detail a workshop needs, VIN included, so you can decode the build. What we don't hold is the person: no keeper name, no address — that isn't in the data we receive and never reaches us. Your report is tied to your code and isn't published or indexed.
