The transistor pictured at the beginning of the thread is the ignition driver.

Adding a ballast resistor reduces the current going through the transistor, reducing the temperature.

Two pins on the DME going to two injectors each, but only one driver sinking current from all 4 injectors. OEM sequential systems use high impedance injectors with a low side current driver for each...

All the latest VW/Audi/Porsche Alusil blocks are now machined using a 3 stage stone honing only process, no more etching paste w/felts. Has anyone seen this offered outside the factory?

If the injector wiring is shorted together at the injector connector it will only bypass the injector, killing fuel to that cylinder. It would have to short to ground on the DME side to fry the...

I've bottomed mine out on a dip in the road once. It scratched up the bottom lip but didn't crack the piece. The metal reinforcement is thin metal. It is definitely not a functional replacement...
