I haven't looked inside it to see what type of chip he uses, but are the RPM settings permanently stored or do you lose them with a battery disconnect?
Thanks.

 

Mine doesn't loose the settings when you disconnect.

I've heard he stopped making them. You can always pull it out and push the button nubmer 2 to see if its still got the right settings in it

 

Thanks.
I was thinking of putting mine behind the vent which would make it difficult to remove and reset each time the battery is disconnected.

 

If someone has the direction for the shift light they might be able to post them up.
I just went out to his site and the store is down until further notice as of 4/21.

Hopefully someone that already has one installed, mine isn't yet, can give you a better answer.

Anyone have a copy of the directions they could e-mail me...I can't find mine and with the store being closed, I can't get new ones.

 

Its too bad he closed.. I wanted a two step for the LS1 we have!

 

I'm actually working on a similar shift-light/RPM switch/etc... I need to cough up about $300 to get it finalized; (Software, and real PCBs); but when I do, I'll probably be offering a similar product.

And the settings are stored in non-volitale memory; thus if you remove the power, the settings remain.
