So I searched the hell out of the site and have tried a bunch of stuff... here is where I'm at, any help would be great, up against the wall on this one. Firmware issue? Bad haltech?
All other sensors are registering.

So I quadruple checked the following...
Proper connection from CAS to loom:
CAS - Loom
Red - Yellow (trig +)
White - Red (trig -)
Green - Green (Home +)
W/Black - Blue (Home -)

and you cant see the obvious error here????
why have you hooked the trigger (-) to the 12v bus??? the whites in the CAS tie together and go to the BLUE haltech wire

ignore the 12V,, its for hall effect and optic senders, not for mazda Vr

Vr negatives are common,, this amounts to the CAS ( whites ) being tied together into the ECU ignition input earth wiring ( blue )

for FC type CAS--

24 tooth multitooth trigger in the CAS ( red ) goes to input trigger ( yellow )
2 tooth home event trigger in the CAS ( green ) goes to HOME input ( green )

Any cure to this problem? my car is down at mazdatrix getting a ps1000 and they are having the same problem.

Nothing yet, PM me if you find a solution. I was thinking of sending the Haltech out to have someone swap it into a working car and see if it is a ECu issue.

Your wiring diagram refers to an E8, this is an E6x, the wiring is correct.
http://www.hitman.hm/installation.htm

try it, i am pretty sure i am right
cause thats exactly what i have done on a previous E6K ( on a 13bt ) and also for a toyota 1JZ on an E6S ( which have notoriously difficult Vr )
and also have on my current e8 setup

the 12V has no place in Vr systems !
( check out also the sprint 500 notes ! )

what do you have to lose????
one snip, one solder at the CAS, join the CAS whites to the haltech blue wire, bingo, crank signal

i am having the same exact problem, no rpm or any trigger or home counts at all

should add some specifics sorry, also e6x, manly stock setup, have all trigger settings correct will not pick any signal with any combination of gain and filters

i did this way back had the same problem. double check hitmans wiring diagrams with another and i bet you find a difference in the cas wiring diagram

Your CAS wiring is correct for the E6X. The E series has a different pinout for the trigger loom than the E8. The E8 is different than the E11v2.

not trying to ignore any advice, but i didnt use hitmans's, mine came with a cut harness that was very short so i extended all the wires and labled them per the haltech diagram on there website, then i used bdc's notes, ill double check the wiring again tomorrow when i get the chance to and compare with hitmans
