does anyone have oscilloscope data for series I rx8 wheel speed sensors?
I am trying to use haltech for traction control and it's asking sensor voltage at 500, 1k, 2k, 3k, 4k, 5k, and 7k wheel revolution. I don't have any oscilloscope to find out.. does anyone have this data handy for our wheel speed sensors? Thanks in advance.

thanks for the response. The reluctor sensor generates higher voltage amplitude in sine waves as wheel speed goes up.. haltech needs to know the amplitude voltage to pick up the speed sensor signal properly..
I may have to buy an oscilloscope just so I can measure it.

oh man that would be awesome. It would help out with anyone looking to go with aftermarket TCS solution since most detect the wheel speed with ABS sensor. if there's FSM PDF available, I would love a copy, and will look into it as well. Thanks!

yea I just found it too... it looks promising. has all the variables I need (voltage and ms which is inverse frequency). maybe I'll just wait until your grounds thaw
haltech wants multiple points (voltage and frequency of sine wave) at multiple wheel rpm's, so unless someone can make sense of that equation, oscilloscope is the way to go.

I did simple math..
it's 0.0773106060 x rpm = mph on the dash
so for rpm=500, it's 38.7 MPH
for 1000 wheel rpm = 77.3 mph
for 2000 wheel rpm = 154 mph
for 3000 wheel rpm = 231 mph lol
this is little ridiculous.. so I asked haltech whether they really expect us to rev the car upto 231mph, and they said if we just fill in the 500, 1000, and 2000, the computer can extrapolate. besides, I don't think I would need much traction control after 154 mph

Forgot about this thread. Attached chart works after 25mph. Can't get it to detect lower speed. If anyone can help out with oscilloscope for 5, 20, and 35mph voltage amplitude, that would be really helpful, but if not, this chart works after 25mph on rx8 which isn't too bad. It lets you do little burn out and by the time it hits 3-4k in first gear, you have traction control kicking in so works great for turbo rx8's.
