No Engine speed... out of ideas.
I have checked double checked and recheked everything. My CAS does not seem to be talking with my Haltech E6X, the connections are right, While cranking it shows 0, I did see it go up to 60 once but that was the once and only time, could my CAS be gone, or the haltech have an error?

try another cas? you can plug it in and spin it by hand to see if it works.
how did you hook it up? e6x is different i think, than the e6k

Check out K2RD?
They have wiring diagrams posted.
Also, some guy mentioned on the Haltech Support list that the CAS wire colors were wrong when inspecting the pick-ups in the CAS itself.
You might want to verify that the wire pairs are going to the correct pick-ups in the CAS by popping off the cover.

You want to verify that HOME wires are connected to the pick-up that tracks the two teeth gear.
TRIGGER wires should go to the other pick-up that tracks the 24 tooth gear.
We won't worry about polarity until you've confirmed that the wires are connected to the right pick-up.
Also, if you're using the stock CAS plug, you might want to take it apart and clean the pins. I've run into LOTS of headaches tring to reuse these plugs on Haltech installs.

I had already pulled apart and cleaned the pugs and pins prior to splicing it with the haltech harness.
As for the pickups, they are correct.
Fuses are all good... and still no Engine speed..
This is really starting to frustrate me... this is all i need to get the car on the road!

dont you have to wire it differently, because the e11 and e6x have the ra8 built in? mine works but i dont remember how its wired up. i think you just ground the - side of both pickups?

alright today I went to try a new CAS, and now my laptop will not communicate with the Haltech, I mean nothing happned to the laptop, because it stayed in the car... never moved. so what would cause this... could my haltech have a problem?

built my own engine
i am having the same problem, double check your grounding on the ECU...
please remember, there are essentially two grounds on the haltech harness, one really long black ground which grounds the relay to turn the haltech on, i assume this is done properly since you are communicating with the haltech via laptop
the other is rather short, and if not grounded, the ECU has nothing to ground the CAS with, I am currently experiencing this same issue, and have discovered my ECU ground wire to be loose, I have not tested since tightening....letting my battery charge back up

verify all wiring to the correct ECU. I do not have any experience with the X model, but I have had a similair problem with the K model. the ECU did not read the CAS signal correctly. after trying several CAS's I called the guys in Australia and they said that sometimes the ECU had to be modified for different OEM type pick ups, they said a "pull down resistor" needed to be removed and it should work fine. I spoke with someone at Haltech USA(when there still was one) and I sent them the ECU and when it returned it worked correctly. I never could tell what was done, but it worked after the FED/EX trip to dallas and back to LA. I don't know if the X model has any of these issues, but I would call and talk to the tech guys in Australia if the wiring is correct and sound. the Mazda CAS is very robust and isn't prone to failures.

I just encountered the same problem yesterday. Does your injector duty cycle and timing read zero in addition to your engine speed? If so, then it should be either the cas or the wiring to the haltech shield wires.
I checked the wiring and it was correct according to Hitmans site so I figured a connection or the cas itself. I clipped off the stock cas plug and sautered a gm 4-wire weatherpack on Then I clipped just before my sauter job on the Haltech side where the stock plug was wired on and also (obviously) sautered on a gm weatherpack.
Basically I had either a faulty sauter job or the plugs themselves were bad because I wired it up the same as before (according to Hitmans site).
Problem solved in my case.
Or a bad ground somewhere. Someone (RETed maybe?) just posted pics from the inside of the Haltech loom and the ground wires were sautered together like ****. Supposedly many (if not all) are like this. Of course I found this out just after mine was installed. Could be worth looking into...
