I haven't bothered switching the tach wire from the 6th ignition output to the 6th injector output (with a pull-up) yet. I did notice that my VE values are seemingly far too high. I have e85 in the car, and it was testing ~70% ethanol when it was parked with the Microsquirt. I haven't wired the Flex sensor yet, so I set the Stoichiometric ratio to 10.7:1. The VE map isn't really "tuned" yet, but pretty sane values below 100kpa seem to exceed 100 for VE. I have the injectors set at 300kpa/550cc (they're out of a late model WRX, people often refer to them as 565cc or 550cc). It IS returnless and set for "fixed pressure". It feels like either the fixed pressure, or 10.7:1 stoich are what is causing the issue. I still am tuning for 14.7:1 scale in the target map, which I believe is "fine" even if switching the project to lambda is "best practice"

I've included my VE map that's been touched only by autotune, I started with a AI VE map from the AlphaX site, since I was going to auto-tune 75% of it anyways, and multiplied it by 1.4x, since idle needed about 1.4x to be happy. Also, I got my uaDash hooked up, I did turn on the 120ohm resistor on the Waveshare display, but didn't hook up a resistor on the UAEFI, and it still works fine. Should I bother with a 120ohm resistor there?

Link to the msq if anyone wants to help whatever is causing me to require higher VEs:
(ignore that my timing is fixed here, I forgot to change it back after double checking my timing with a timing light)
