Hi I'm wondering what software is best for tuning denso ecus through obd2 port. Specifically Toyota Hilux kun26 1kdftv d4d models years 2006 to current with 175800-8471 denso number on ecu and Toyota Land Cruiser 1vdftv. I have kess v2 software and can't access either. Do I have to purchase ktag and do ecus on bench or does fgtech work through obd2 or a different software.
Cheers
