Very cool. Why only 2? I guess the procede will pass through the analog signals when off?

The relays emulate the bypass plugs. When you turn off the car, the Procede will be switched off as well and the relays close. The rest is done by the standard harness

Ahhh, great info. I knew I should have gone in to EE.

A little late to this discussion but what is the desire here; just to have the procede shut off when the engine is off? Sorry, but that is all I garnered from browsing the thread.

This configuration really has some advantages. Thus the relays are intercepting the PROcede harness, you will never have a "disconnected" status, even not for a nanosecond

When you install a remote power on / power off switch for the PROcede, you will be able to switch back to stock. No need for a stock map, ideal for diagnostic purposes. There is no need to wake up the PROcede when the car is off thus the bypass plugs are virtually installed.

You only have to add another relay in the future when Vishnu adds another wire to the bypass plugs and you will exactly know where

p.s. 1 relay has been < US$ 1.00

Eugen, are you still working on the wireless solution to map up and downloading?

That does make more sense.

What kind of relay are you using? Obviously not mechanical...

The reason I ask is that I have wanted to look into making a mating harness to ease the install removal process of the procede. Building the relays in might be advantageous when under construction.

Yes and it works already, but don't expect effective datalogging functionality. It's slower compared to the physical cable.

All fine but slower.

The PROcede itself will be connected to switched power.

Thanks, Eugen!

Mechanical. Finder 30 series subminiature D.I.L. relay 2 A 30.22 / 12V. Industrial / automotive use, RoHS. You hear a nice, silent klick .

You can expect the DIY PROcede wireless remote access within the next 2-3 weeks. It will be a challenge for me to describe how to set up the devices easily .

I also tested the approach to get it to work using the laptop's built-in bluetooth interface. The PROcede reader is not able to open such a COM port. Also, please forget about all those Home-Office devices. Using 2 SD100's emulating the cable is rugged and works good ( for me ). I don't care about e.g. to have to wait a little bit longer for loading a map when I can do it without touching anything mechanical in the car. Currently the SD100's are running all the time to verify that all is good before I will motivate you to spend ~ US$200 for the 2 devices and propably getting issues. It looks very, very good except you plan datalogging ( to slow, at least for me ). Its a professional solution and supports overall PROcede reader functionality.

Sorry for offtopic.

Being mechanical there has to be a momentary open period. Granted the gap may be minimal but it if can support 2 Amps at 12 VDC it will have a latency period when no contact is made. Otherwise there would be a short between the throws.

However, the period is most likely in the µs range.

Interesting endeavor and something I will be eagerly following. Thanks...

Sorry, your guess is wrong. You cannot disconnect something which is physical connected all the time. The only thing I do, is short-circuiting these wires. The origin wires are still there and not interrupted in any way. The relays tap into the wires.

Thus normally a car idles before the engine will be switched off and the PROcede doesn't intercept signals in that rpm/load range you are on the 100% safe side , again without any nanosecond of line interruption. The ECU won't see something unusual. I wanted to make it like this.

That's why it's that safe.

No guess, just curious based on experience.

Are you saying that with this relay both throws will, momentarily, be connected concurrently? In other words, there is no 'make and break' for this relay?

Coming from the industrial controls industry, we deal with relays daily. But most are opto or mechanical and all mechanical we work with have an 'open' period.

I apoligize but I am not following. I did a quick diagram, please excuse the MS Paint rendition, to show what I have envisioned is the method. But I can certainly be way off.

No ...

I will post it tomorrow in this tread, it's 2 am already here.

You will see, it's really simple. Perhaps unusual

Thanks, and get some rest. I was beginning to wonder if you actually slept.

Sorry, just jumping ahead and will look for the correction tomorrow. But I was wondering if you were allowing the PROcede driver to force the voltage level as in the below:
