Data-drive™
Road-test logger
A road-test data logger for the workshop, to be used alongside a scan tool. It produces data-based figures you can use in the diagnostic process, and reports that help establish and prove an effective repair.

About
Data-drive takes the readings available on the OBD port and makes them usable. Known formulas turn that stream of data into a general picture of engine health, performance and efficiency: how well it is breathing, how it is fuelling, and what it is making. Those figures can aid the diagnostic process, beside the scan tool.
The data can be exported, and it can be printed. The technician keeps a copy for the job. The customer gets one they can read, with the registration on it, so the repair is something they can see. If the car comes back, the next trace has a reference.
User guidePlansTools
Each one opens on its own. Nothing is tucked behind another card.
Vehicles
More than one car. Pick the card, then tick its tools.
Battery and charging
Key-on, the dip while cranking, then running voltage.
Live data
The channels for this job, and up to four on one graph.
BHP
An estimate from the pull. Not a hub dyno.
VE and BHP together
One pull, both graphs.
Relative compression
A long crank. A low slot is worth a gauge.
DPF pressure
Idle, then 2,500 rpm. A restriction index and a graph, not dealer soot %.
Freeze frame
What the ECU stored when the fault set.
Mode 06
Catalyst, O2 and EVAP, pass or fail.
The log
Saved road tests. Mark A and B, then Compare.
Android only. Use a workshop Android phone or tablet, in Chrome. An iPhone or iPad cannot open the adapter.
It also needs a decent Bluetooth LE OBD-II tool. A Veepeak BLE+ or a similar ELM327 BLE adapter is what it was built around. A very cheap clone often connects, then smears the pull.
Generic OBD-II only. No coding, no adaptations, no security access. Privacy
