Vapor Trailtech

[darren]

Can any body help with my Vapor trailtech.

I have a 1998 EC250

I have been trying to set up the PPR (pulses per revolution)

There is three pages in the book in the data setting mode
Step one needs to know how many pulses per revolution the options are 0.5/1/2

Step two states that the pulses on certain vehicles change over a certain RPM, I need the RPM that the PPR changes (if applicable)

Step three is subject to step two, if the PPR changes at a certain RPM then the PPR needs to be ammended again options are 0.5/1/2

I have checked the trailtek website just to see if there is any information with regards to makes and models unfortunately there is nothing there.

help would be much appreciated.
