Default Re: Differences between v2 and v3?

The differences between v2 and v3

HFS3...
1. V2 has one flow table compared to 3 on v3. It may not read Di signals after 2010.
2. V3 has a more advanced Di signal decoder that will handle 99% of the engines up to 2015
3. V3.1 can decoder 99% of DI signals from 2008 to now.

Flow sensor/failsafe construction, gauge and controller circuitry has also been improved.
