Nice lookin scirocco.
Maybe you could help me, I am currently running MS1 with a V3 board and spark invert, dropping the coil with the VB921. How are you running your spark...it looks like you still have your distributor.
My distributor is turned as far as it can go (in the advanced direction) and my timing is still offset from what MS reads to what it actually is with a timing light. Like off by 24 degrees. Actual will be like 18 degrees After TDC and MS reads 6 BTDC.
Did you run into any problems like this???
Also I already am using the bolt location for the distributor that allows the most advance. I have my trigger angle set to 60 degrees.
FYI: I'm running 029t.
I attached my msq

I suppose I could try that but in Megatune it says not to have a trigger angle below 4 degrees and that 24 would bring me to 36.
I think I am going to try and rotate all of the plug wires on the distributor one cylinder over and then retard the distributor a bunch and see if I can get that to work.

Seriously guys I have done several dozen MS installs on VW's. If the engine is timed correctly and the wires are on right, a trigger angle of 62 degrees starts and runs dead on EVERYTIME. If your trigger angle isn't 62, something is goofed up. I almost NEVER have to adjust the timing either on the dizz or in MegaTune. If I have to, the car was incorrectly timed before I started on the MS setup.
LOVE the engine bay and fabrication work on the rocco!
