Frequently asked questions

Can Softechpro tune the Denso (Toyota)?

Yes. Softechpro Solutions reads the Denso (Toyota) map, applies the requested service (DPF/EGR/AdBlue/DTC off or Stage tuning) and recalculates the checksum & CVN so the file is flash-ready.

Does it correct the Denso (Toyota) checksum automatically?

Yes — every Denso (Toyota) output is checksum and CVN corrected automatically. You can also use our free online checksum tool.

What hardware do I need?

Softechpro is software — it processes the BIN/read you obtain with your own bench/OBD tool (KESS3, Autotuner, Flex, KTAG, CMDflash, etc.). It does not read the ECU itself.
