Tools the software directory
Volvo software, in one place — with the maker credited and linked. We archive the freely-distributed tools so a working copy stays available; for the paid ones we send you to the developer. Most of these need a DiCE (or a good J2534 clone) to talk to the car.
● P3 CarConfig & keys
Read and write CEM CarConfig, search the CEM PIN, sync BCM settings. A one-time-fee tool built as the alternative to per-change subscription pricing.

Re-use an old Volvo P3 key on another car — clears the transponder's immobiliser marriage by reprogramming the PCF79xx chip. Ships with 5- and 6-button key firmware and the BluePill programmer firmware.

● CEM PIN cracking
Recover the CEM security PIN by exploiting the seed/key timing — the DIY route to the same PIN P3Tool searches for. Open source; build from the repo.
| Maker | vtl |
| Needs | Arduino / Teensy + CAN shield |
A purpose-built CEM cracking dongle so users get quick access to their own controls without building a rig. Not released yet.

● Engine & transmission tuning
ECU tunes with the maker's own softloader + logging over the Volvo DiCE — the differentiator over other tuners. Software + tune delivered with a licence key.
| Maker | Robert Hilton |
| Needs | DiCE / J2534 |
Transmission (TCM) tuning for the Aisin TF-80SC / 8-speed — sharper, firmer shifts and improved torque-converter lockup. Also ECU tuning.
| Maker | RICA (Netherlands) |
| Needs | DiCE / J2534 |
● Other platforms & official
Diagnostics and CarConfig editing across the older platforms. Capable, but priced per change / by subscription — which is exactly what P3Tool was built to sidestep.
| Maker | D5T5 |
| Needs | DiCE / J2534 |
Diagnostics, configuration and flashing for the newer Volvo & Polestar platforms — the SPA/CMA equivalent of what P3Tool does for P3. Enable paddles, drive modes, Polestar tweaks.
| Maker | SPAyceTech |
| Needs | DiCE / J2534 |
The official dealer workshop + diagnostics system — the source of truth for procedures, wiring and part numbers. Licensed workshop software; we run it, we don't redistribute it.

We don’t make these tools and we don’t take credit for them — every maker is named and linked above. Archived copies are freely-distributed or open-source software, mirrored so a working version stays available; verify the checksum and prefer the maker’s own download when it’s up. Paid tools are link-only to the vendor. Editing a car’s configuration, keys or ECU can disable features or brick a module — back up first and work at your own risk.
