SRAM based NVRAM

It's a really good idea having that there. I personally had my NVRAM randomly brick itself an hour from home just outside Gareth's workshop at the time. Luckily I had my OG memcal mounted on the NVRAM, so limp was able to get my car running enough to get off the side of the street and into his workshop, where I proceeded to re-flash the NVRAM chip in the programmer. But this could have happened anywhere really, and so the ability to limp the car is essential in my opinion if you haven't burnt a memcal yet.

That was even with a modified engine with way different everything, the limp still worked good enough to run it in an emergency. It will be a worthwhile feature to have while saving a ton of space by not having a memcal hanging off the side.

That was exactly my thoughts also. It all measures the same on paper as per the original memcals I measured withing 0.34% so in theory limp home should work.
Last step will be to clear the memory and see what it actually does in a vehicle.
