The original Bosch module for GTV6/Milano is 0 227 100 111. There are many Bosch modules which look alike and have similar numbers but it is hard to determine the difference. I bought a 0 227 100 100 equivalent on ebay New Ignition Module Bosch for Lada, VW Golf, Jetta. Made In Usa - BM300 | eBay
thinking that it would be similar. I tested one of each today and they perform differently. The 111 is a "smart" module and it modulates the dwell angle and coil current to keep the average current below 0.7 amps. The 100 module is not "smart" and it drives the coil in accordance with the dwell cycle of the signal that it receives. It is a good choice for a Megasquirt ignition where the dwell time is controlled by MS but it is likely to cook the coil if it is driven straight from the Hall pickup, as on Milano's and GTV6's.
