I build a new AAN Genboard V3.8, with Hall/Hall setup. For ignition i want to use 5 Logic Level Outputs. I connect the gate withe the output and soldered a second 510 Ohm resistor parallel to the other 510 Ohm resistor.
If i measure now the Logic Level Outputs, than i have all the time 2,5V and in the Ignition Test Mode, the Voltage jumps only from 2,5v to 2,7V.
It is possible that i destroy the 74HC259 Chip?

Home build AAN from Genboard v3
Soldering:
Reenforce soldering on TO-220 componets's GNDs, they really weak at this time.
IAC:
A shottkey diode will need from JPT55/4 (EC36/6) to the flyback JPT55/37, cathode face to JPT55/37 (Solder the diode's cathode to the anode of the 30V flyback diode, this is the easiest way.)
Ignition:
Remove all FET witch is in the place of an IGBT and solder an 510Ohm(1206) parallel with the soldered 510Ohm(0805). After this connect the gate with the output in the place of the removed TO-220 component.(Wire the signal from the two resistor to the Econoseal pin.) You need to do this only on outputs used for ignition.
Insulating:
Stick the teflon sheets to the metal case, this way the components will insulate from the case as well as from each other. In the end recommended to make insulation test with a lamp. Connect one pin of the lamp or anode of a led to +12V, other pin or cathode to the metal case. Start to test the injector outputs in VemsTune one by one. If the lamp or led ever lights up, the insulation is bad. You need to fix it.
WBO2: If you not reuse or add wires to the factory harness, it won't work as it connected now.
Both of the controllers has factory AAN configuration, if you ever miss them up you can download or we can send you.
