New ISG auto-off module in development (no more testers needed)

[sprengBoard]

What's the price point gunna be at with these ?

Don’t have a set price yet, but I can assure you it’ll be very competitive.

Tested the module temporarily in my car this morning. One small change is needed to a resistor value, otherwise it works great (sitting in my driveway). I’ve made the change along with a few other minor revisions and have ordered another prototype batch. I believe I have the parts necessary to modify the first proto boards - I’ll do that this afternoon and install it permanently in my car. @arattle @Socal949 once I receive the revised version (which should be a couple days faster than the first batch) I’ll send you each a module to test.

The one thing I’m not sure about is availability of +12V power. One of the wires on the connector should be +12V, however someone else a while back mentioned they couldn’t get some other kind of module to work using it - they had to tap into an accessory power wire. Sure is difficult developing this for a car I don’t have access to (yet)!

@gn3rps Sounds good. Keep me posted and PM when ready and I’ll send you my address

Found appropriate resistors in my stash and replaced them on proto board 1 and it functions 100%. Video coming shortly

You are a genius! Can’t wait to try this out. When do you get your Telluride?

I’m hoping my order will get picked up this month….if so, maybe around the end of October.

@arattle @Socal949 can either of you, or anyone else, verify if pushing both the ISG and auto hold buttons at the exact same time enables/disables both functions, or only the one that the computer sensed first? Working on not only optimizing the code, but also adding a memory function to remember the last state of the two functions (if function is on when car turned off, it will be on when car is turned on next time, and vice versa). Need to know if I can call both commands at the same time to toggle the functions or if I should only call one at a time.

Just tried it about 5 times....it works. I'm not a computer but I tried to be precise. Every time both functions activated/deactivated simultaneously.

Awesome, that’s nice to know! Revision 2 with memory for both signals is 99% completed. Code has been written and tested on the computer, PCB has been redesigned, and a temporary circuit I put together on my bench works. Going to try modifying the original prototype with the necessary additional components/connections and test it in my Honda. Once tested in my car I’ll order a batch of the latest modules.

I really don’t feel that the memory function is all that necessary because people that would buy a module like this and go through the trouble of taking apart the console to install it are doing so because they want the ISG to always default off and/or the auto brake hold to always default on, however there only a few extra components and connections and a few more lines of code to give it memory capability, so I figure why the hell not?

I can say this is absolutely true. Just tested on my car as well with the same results

I think memory is an essential feature. I don't know in the future if there may be situations where I want one or the other back on again - and I don't want to pull the dash apart again to change the state. This seems to me like a primary feature for the product to be viable.

Good to know others’ opinion on the matter. Memory function will be included

I don't know what you guys are doing, but it sounds exciting!!!

Haha, indeed! At least for me, anyway (I love this kind of stuff).

Rev 1 (changed resistor value, no memory function, separated LEDs for each signal) scheduled to be delivered this coming Wednesday. Once I receive it and test that the changes are functioning 100% I'll place a new order for Rev 2 with memory function.

Been working on optimizing the code. One thing that needs to be noted is that the ISG/Auto Hold buttons should not be pressed between the time the ignition is turned on and the module runs its functions 3 seconds later as the vehicle functions likely won’t change during this time (the vehicle’s computer is still booting up).

On the very first startup after installation, the module will default to activate both functions (turn ISG off and Auto Hold on). If these settings are what's desired, nothing more needs to be done - you'll never need to press those buttons again. Once the module runs its functions for the first time, you're free to enable/disable the two functions as you wish, and the module will remember the last state.

Love the great news. Can’t wait! Thanks for sharing your knowledge and providing this to the Telluride Community.
