It's also possible to drive the SOC gauge on the dash with 19 bars soc or whatever you want with the addition of an RS485 line driver chip.

You could also drive the IMA light to mimic the start up sequence for that as well.

If you wanted to do both of those then we need a slightly bigger pic.

This sounds excellent! I'm gonna reset my trip and drive this rest of this tank without using any assist and see what kind of mileage I get.

I just grid charged my battery this weekend, and immediately lost a bar after using some assist, got it back, and lost it again after using it. Grid charging didn't seem to help my battery at all, this time.

How far did you end up driving it with it installed? I saw in your YouTube video that you had driven it around 20 miles, at that point. I assume the car will drive pretty much just like it would if the clutch interrupt switch is depressed? Also, can you still use air conditioning without the IMA? My assist pretty much kicks in immediately when I turn it on.

I like this idea, it'd almost be like nothing changed for me, except having less power.

Yes you can use the air con.

I only drove it around 20 miles as I hate the car without the IMA so only fitted it for testing purposes.

I don't intend to do any work on the schematic/code for driving the IMA light and soc gauge unless some people actually buy and use it.

The schematic I have published works fine as is.

This is something I am very interested in and would like to thank you for you contributions to our community!

I don't think it's necessary as no one in inspections knows or cares if the IMA should blip on startup or how many bars soc you have. Best to leave it as is so potential future buyers will know whats up.

Does it come with instructions on how to build and install?

Are you certain you can lean burn with this while the battery is removed? I heard the car needs to have the IMA battery to be able to leanburn. If so i want to buy one.

The instructions (schematic) are in the thread on IC.

ASFAIK it lean burned fine when testing.
If it doesn't then if you send it back you can have your money back.

You might be happier installing a MIMA which would allow you to cut out the IMA for those long climbs, and then drop it back into the mix when you're done with the mountain.

+1 on pig. I have a 1.5 mi. climb on my way home and an IMA light showing, the batt capacity is down to maybe 40% of new. Regen during climbs bites hard. And no, I don't have a MIMA either.
