So I spent this past weekend putting a Vortech V1 on my 1992 GLI.
The car had an OBDII VR6 swapped in from a 1998 Passat, and the motor was fairly stock, with the exception of EGR and SAI, which were gone, and programmed into the existing GIAC software.
Here is the current configuration:
42 lb Bosch green top injectors
Vortech V1 with 8 lb pulley
C2 42 lb race profile software - OBD II
Walbro inline 255 LPH fuel pump, relayed off of mkII intank pump.
We basically spent all afternoon yesterday trying to chase down an issue with the motor not getting fuel, only to figure out that the connection we were tapping into for the inline pump was corroded.
I wired in a 30 AMP relay, using the factory harness going to the mkII in line pump assembly as the signal source. The fuse and relay are mounted in the fuel pump well with the Walbro pump.
We got the car running pretty well last night at the shop with a little help from the Vagcom and mostly just a lot of going over things and making sure everything was tight.
Here's the idle video
I let the car cycle through two cooling cycles and ran it up and down the back street behind the shop, to make sure everything was good to go.
Drive it home - 20 minute drive, and 2 blocks from my house, the car cuts out.
I checked the relay and fuse... both under the car, and under the dash, and all were good. The ECU is not sending the signal to the fuel pump to turn on.
Where do I go!? This is driving me to drink!
