I'm an idiot that's been staring at diagrams for far too long. The wire is actually 57 which is the output for reverse...

So on my pre-made harness 51 is red 52 is green and 53 is red. I also thought this made no sense. 51 and 53 are tied together into 1 large constant 12v wire.

Green is repeatedly used in the harness for things like the LCD, program switch and shifter for power. I'll take a picture tomorrow

Using emu black. Perhaps there's a CAN setting on the ecumaster software. It doesn't time out at all unless I undo the green #52 wire. If I then turn the key back on with the green 52 unhooked, the lcd powers on like normal and then with the key off it times out after 30 seconds as it should.

after switch to the 10.74 firmware all is well. voltages didnt change but the input value changes and the shifter now lights up on key on and i can shift gears. in Manual shifting however im only able to shift down to 1 and back up to 2 no futher, not sure if its an rpm thing as im not actually ...

im making sure i do that from now on. im confused on why the voltages are different depending on key being on or off. also why the shifter lights up sometimes for a few seconds and other times it doesnt light up at all.

is it supposed to be reading 5v signal or 12v?

So looking at analog 7 voltage now it shows 3.5v and 5v depending on pedal pressed or depressed. Main dash foot brake value never changes from 1

Key off it ranges from foot off 0v foot on 5v

i do show to have the enable flag. so i guess i need to upgrade firmware. ive noticed a couple times of trying to upload or download the bin file it says something about the file being bigger than the ram?

im trying to make sense of these files and the random numbering that must be dates. i ...

everything connected and trans filled as much as possible at the moment. i still cant switch gears. almost seems like it doesnt recognize my shifter which is set to type 36 for the a90 supra shifter. i cant find anything that shows brake pedal voltage and still stuck showing a value of 1

went in to make these changes to find it already set to 30 seconds but its still staying on. perhaps i have something wired wrong. originally i had 51 and 53 wired to key on relays without the green 52 wired at all and everything "worked". after rereading the installation manual i realized it was ...

While fixing other issues with my setup i realized i didnt have 51-53 wired to constant battery voltage. After correcting that my LCD screen stays on regardless of ignition position. if i remove the green wire #52 it goes off.
