Where can I get an RPM signal....

...for my EBOOST 2. It can also serve as a super accurate tach and the rpm signal allows some advanced features for boost mapping, etc.

I am looking for a square wave pick up point.

Any wire at any coil or fuel injector that is NOT red or red/light green will be your tach signal. Remember to multiply the signal for 8 cylinders.

I picked up the rpm signal for my Dynojet Wideband Commander from the connector on the driver's side firewall (pin #3, COP cylinder #4).

Thanks!

How did you connect it? I saw the description for the switched power you used, but nothing on the rpm signal.

No, that is the PPM wire and measures pulse per mile for speed dependant volume. It is gray/black.

See the 2nd post on that thread. The WBC came with some 3-M Scotchlok t-taps. I hadn't ever seen them before... they work great, but they're a bit pricey:

The above link has a good picture, but you can find them on other sites cheaper.

A regular wire tap would work, but a good soldered connection would be better.
