I wanted the ASV because I wanted the Euro tune with the Euro maps. The engine drives differently than the US maps.
When I say "fires off of a different pin", a different pin goes to ground to make the GP relay operate. I also added in my own momentary switch so I can manually operate the glow plugs.
When I got the ASV flash, my glow plugs didn't work.
1. wrong ECU pin
2. ECU didn't operate the smart relay
Jeff at Rocketchip has since figured out the glow plug/ASV thing.
At the time I did my swap, eliminating the IMMO wasn't yet an option, nobody had figured that system out yet. This means I'm using the mk4 cluster in my mk1 dash, and I'm running the full IMMO3 system. All the lights work, the CANBus gateway has been coded to eliminate missing equipment. I do have a DTC for missing ABS and Airbags, but it's not an issue shown on the dash, only during a scan.
