Deactivate Start&Stop (ISG)

I spent an hour or so probing all the wires to the connector, and found the signals I needed.

So here is a video of the prototype 'fitted' to the car, turn on captions to see what's going on:


Now it has been tested, I'm putting together a neater version of the hardware

Nice will you also be workign on a module to make the car startup in custom mode?

This would be a bit to much I think. And you'll get problems with your warranty. It should be possible to measure the N button wire, when it's not wired in a matrix or networked via CAN.
 
Awesome job you did there!! Will you produce units for the forum members too?
Thanks! It's just a hobby thing at the moment, but maybe, I'll produce a decent compact version first, then see what I think

Interesting idea. All it'd need to do is simulate a double press of the right flag button shortly after startup, so shouldn't be very different from this ISG module. As here, the main issue will be identifying and accessing the relevant wires
Food for thought: Link, link and its full specs here.
Cheers, yes could buy off the shelf for this one, but I like a bit of DIY

Great piece of work... Love to see examples of electronics of this nature... being designed and made as a... "thought i would knock one up" in my spare time.
Nice to have such skills in electronics.... Well done.

I found this on a german site. what do u think about it?

Minus-Version needs following parts:

1x ATtiny13A (nicht 13V)
1x LP2950-3.3 oder 78L33 Spannungsregler (LDO)
1x 1µF Kondensator Keramik (oder größer)
1x BC548 Transistor NPN
1x BAT43 Schottky-Diode
1x 1 kOhm Widerstand
1x 10 kOhm Widerstand
 
Hi guys, I've been running the first prototype (as in post #70) in my car for a little while, all works as intended.

During this time, I've drawn up and had made a batch of 3 PCB's, to make a neater (and easier to assemble) version:

Here's the fully assembled module, which has now been swapped into my car, and works as before:

So the time has come where I could make up some more for anyone interested.

One thing to note, my car is a UK RHD model with heated seats, and I've used a signal line used for the heated seat switch, as this is the only one available at the multi-way connector which indicates when the ignition is on. So if you have a LHD car, or no heated seats, someone would need to confirm first that the connections needed are still present at the multi-way connector. (Chances are that they are, as cars tend to have common wiring looms, and certainly on mine there are more wires to the connector than are used).
Also, any work done on your own car is entirely your responsibility!

I reckon it would be best to supply everything needed for an installation, which would comprise of this module, the other half of the 5-way connector, 5 piggy-back connectors, and some velcro sticky pads to mount it on the inside of the transmission tunnel near ISG switch. I could do these all for £20 (may be revised depending on part availability and effort required!), plus whatever it costs me to post it to you.
As I hope you'll understand, I'd only order in the parts and build them for definite orders, and some parts are best ordered in small quantities, so it could take up to a few weeks. And also please remember that this is a background 'hobby' for me.

Let me know if you'd like one!

Great work!
Any news about the "set driving mode to custom automaticall" device yet?
Thanks. That is something I also fancy having myself, I've worked out I can do it with the same hardware as this ISG module, and I've even written the firmware, the thing missing is finding the correct wires around the dashboard somewhere, any help with this will be rewarded!

I have looked for this in the Hyundai GSW but it did not show the scematics for the N mode buttons :confused:
