    I know the HPT bypass only connected one of the two cables going into security module so assume this is a "Single Pass" unit Have seen statements of "Double Pass" units and is what AlfaOBD told me I had to have. I could not get a return confirmation when changing tire size from the BCM module. Sent message to Alfa saying wouldn't work. They recomended SGWlink bypass from Zautomotive. Noticed right off had both cables from secutity module connect to bypass. No connection at all to stock module.

    Was nice that made HPT ABS Initialize command work after installing new bypass.

    Wonder if one of the HP reps are willing to comment on the differences in the bypass cable?

    Dought it as I contacted support several times through last year asking for any news on getting ABS initialization to work and was told nothing new.

    Do you know what Proxi alignment is or does? Have seen various mentions of it to fix problems with ECUs. Searching for way to fix loss of Park Sense that was caused by first Tire Size Change part of whole tire and ABS routine. Afraid if go to dealer they will reflash everything to stock Trackhawk. Can not even find what technical name to use for Park Sense. (have seen Forward Collision Control mentioned) Searched through Alfa but no luck on Park Sense.

    Thought maybe you ran across.
