Haltech TII with E6K - road speed value
#2
Lives on the Forum
Did you get it to read correctly???
I tried to get it to work when I was up there, but it wouldn't want to register correctly.
I think the waveform was not something that Haltech likes.
The A'PEXi electronics (i.e. S-AFC and AVC-R) seems to work fine though...

First off how are you reading on an FC for the RSS? are your models fitted with ABS i take it, in any case, the value for the RSS to work correctly needs to be how many teeth the sensor sees for every kilometer traveled.
Also, since on RX-7's this sensor is most likely a magnetic reluctor type this will require an MSD-8509 magnetic signal stabilizer, becuase the Haltech expects a square wave pulse.
Anybody know exacty how many teeth per kilometer (or mile) the sensor sees?

all FC's do have mechanical speed input from transmission to gauge cluster
at gauge cluster is signal converted to electrical and wired to powersteering computer and cruise control computer
i wired haltech road speed signal wire to stock road speed wire which goes from gauge cluster to powersteering computer
i believe its green/red (in S4 TII)

But as you can clearle deduce this isnt a real pragmatical way of connecting it, becuas if you have wheel spin or different size than factory wheels this reading will vary.
That is why i asked about ABS equiped 7's, they do have a wheel sensor, which would be more beneficial and accurate.

Well i guess if you calculate for proper wheel size and dont mind the value increasing with wheel speen then i guess its ok.
Do you know the variables to calculate it properly? Also, there's the question, is that signal the the dash puts out is it a square wave?

Haven't we ALL heard this
Also, if you have the mouse belts there is a wire coming from the gauge cluster going to it.
And the best part the brain / computer for the passive belts is right under the glove box. Take your glove box out and there it is.
I will take a picture of the box and the right wire when I get home.

The FD and FC sends a speed signal to dash may it be by mechanical in the FC's case or electronic in the FD. From the dash the signal is converted to a square wave signal and is sent to the various computers on board. The green wire with red stripe (G/R) is the one .

^^Thats what I did.
With the value at 2500 pulses/km it reads higher then the speedo by about 15% (100km/hr on the ticker = 115km/hr on the haltech)
But it was mostly for reference during datalogging so the actual figure wasn't too important to me. Great little feature though.
