Is your IMA battery dead weight? Want to remove it completely?
youtu.be/c9OZLoJG4RU

Watch this video if you're looking to:
-remove your IMA battery, &
-keep your 12 volt battery charged, &
-trick the car into thinking everything is peachy in IMA-land

Here is the latest schematic and code.

...

Notes:
-Battery Malfunction Light will (temporarily) come on each time you exceed ~4000 rpm... light will turn off once RPM drops down. If you don't want that behavior, you'll need to install an aftermarket DCDC converter (as discussed elsewhere).
-Standard USA EPA Caveat: FOR OFF-ROAD USE ONLY
-Both code versions are now updated to use same pinout. See new schematic for more information.

Nice, thank you! I gotta dig my arduino out and get the new code on it now for those off road track days :) As always, thanks for your hard work on this stuff.

Your bumper sticker leads me to believe that you'll be using this bypass to launch your G1 into space. Now THAT'S hard work. Greetings from a long layover in the Atlanta airport!

Good point- does the EPA have jurisdiction in space? Don't think so!

Unfortunately, that one got launched into the back of another vehicle at high speed by the daughter, so that sticker is hanging out in my garage on my parts car at the moment. That reminds me - I need to order another sticker.

Just as long as it isn't a public road.
Sorry to keep you waiting so long, Balto.
Of course! Always off road ;)! And you are doing this for free on your own time. It's no worries. Thanks again!

-The bug Balto pointed out - that I previously fixed - has been fixed.

My code which is similar to M's allows LB and the normal rev range so I suspect it is the same.. If you fake the signals correctly as we are doing then the car has no reason to turn things down..

I've driven my car quite a bit with a dead pack, first with just the BCM unplugged, and then with both BCM and MCM unplugged. It never really appeared to be in limp mode either time.

Subjectively, when I unplugged both (same as the bypass I think), I got better MPG, and more idle vibration.

Sorry for possibly being arduino inept, but I dug out my arduino UNO from the electronics bin and i'm trying to load the program. I uninstalled the old version off my computer and installed the new software. When i try to open the "IMA bypass arduino code" which is an ino file under the folder of the same name i get an error saying "Could not create the sketch". i can't understand how i'd be doing this wrong, but maybe I am.

I don't think you are, the same thing happens to me.

I had a similar experience, except mine wouldn't start without the MCM... Not sure why the 'limp mode' idea has become a matter-of-fact...
