Vishnu Procede disconnect switch - BMW 3-Series (E90 E92) Forum

Ander · 06-06-2007, 11:03 PM

Question:
Does the Procede function in a passthru mode when it has no power?

Per install video this appears to be true.

If so, can't we just put an inline switch on the exposed engine bay ground? This would allow a simple valet mode without drilling an ugly hole in the glove compartment.

It would require planning ahead and just opening the hood and switching off ground.

Risk: when Procede ground is removed, is there a risk of a negative ground leak thru the wiring harness into the ecm?

Disconnecting the power or the ground will not make the PROcede "passthru". Doing so will break continuity with all the intercepted signals. Use the bypass plug instead

But we'd like to keep it simple for now and just stick with the 2 discrete map limit for now

Care to share which wire, shiv?

If I had to guess, I would say all the magic is on the gray connector... connect pin 12 to ground to swtch maps, and connect a trim knob to pins 8-12-ground to adjust curves. Pin 8 has 5v, and pin 12 is the last analog input, which is where you connect the trim knob

DON't ! The PROcede is not similar to the Haltech unit. My guess is that we all won't have a valet switch, thus the PROcede has his own logic how the map's are stored, computed and processed. I doubt that there is a stock map stored in the device ...

However, a simple hardware solution would make such a switch possible.

Any one of the digital inputs can trigger the mapswitch. The only things, with v2, we are using ALL of the 4 digital inputs and 4 outputs. This means that we are making firmware changes to make an analog input do the map switch. If you guys can wait a bit, we'll have it all sorted out soon

awesome! Thanks!

It seems that I like my procede more everyday! We need some 6"*2" vishnu tuning stickers for our back windows.

My car will be stateside early september, so you have a little bit of time.

"firmware". Does this mean that existing customers have to ship the Procede back to implement the firmware changes?

shiv@vishnu · 06-08-2007, 01:14 PM

nope. customers can update firmware themselved. Just like uploading a new map.
