Rewired both the Eboost and the Digital dash today, the Eboost is toast as it freezes or turns off after a few minutes. The spare eboost unit i had works normally and while i didnt want to do it initially i ordered a new Eboost. The powertune digital dash kept turning off at one point and now stays on after rewiring. Issue is it has some interference and flickers now and then. Powertune have been great though, very helpful in telling me what could be wrong and what to test inside the unit and if theres any failure they'd be able to fix it.
Annnnd both the dash and eboost2 are fried beyond repair. Both have some serious corrosion on the PCB and are unable to be saved. Eboost is on backorder from the 11th of August so i wired in an el cheapo HDI EBC but i havent tested it out yet. On the plus side i managed to get an Apexi EL2 mechanical boost gauge, albeit no harness from a member on here. I'll have to make a harness for the backlight but its a mechanical gauge and works as is.
