Added:
If you disassemble and assemble for any reason (normally not necessary, but unlike many electronics, VEMS ECU is servicable), take the following precautions: take care with the assembly. A thin insulating tape on the 100mm edge cannot hurt. Insulating-sheet under the FET-s+IGBT-s is a must. After assembly, verify that:

* any output pin should not short to the case (verify all output pins, especially inj and ign: with DVM).

* As a measurement, temporarily connect the case with a 10k resistor to pump- (EC18/7=4V), and measure voltage: case voltage should "follow" to appr 4V (+-0.2V). (the case should not short to any other signal like supply-V).

Bridge Output driver (ETC / DBW) + v3 ECU mounted inside box - cooling is important

The wiring is easy (flying loom through frontplate), but insulatorsheet and cooling bridge output driver FETs is important (so it cannot be simply mounted inside without clamping, like active flyback).
