Frequently Asked Questions
Why use DDDL 6.50 instead of DDDL 8?
DDDL 8 is primarily built for newer DDEC VI to DDEC 13 / 16 engines. For older DDEC III, IV, and V systems (including pre-emissions Detroit Series 60), DDDL 6.50 is the dedicated factory tool required for full diagnostics and testing.
Will you configure it with my Nexiq or DPA5 adapter?
Yes, our remote installation includes full communication adapter driver verification and port testing live on your computer.
