VEMS help

[northern_aqs]

I've installed a VEMS system on my 951 and am trying to correct a difficult to start (cold) situation.

The Auto VE analyzer works sufficiently well based upon experiences so far but something isn't correct in the initial config file for my car. Just having trouble getting basic answers. I plan a complete installation thread shortly, but I'm waiting until I get this back to OE drivability.

What should my cranking ignition advance be?
Will running 630cc Siemens injectors effect start up?

The car:

87 951 with stock 2.5 with 22k miles from new
26/8
Siemens Decca 630cc injectors
2.5 bar FPR
It still has the cycling valve and runs 10psi boost on VEMS and WG springs control. I have bought a boost solenoid for eventual VEMS managed boost control but don't have enough info to install it.
New TPS (Porsche part number).

Prior to VEMS install the car started and ran great. It was chipped to 15 pounds boost and running the stock WG.

I've linked to a YouTube video of the car starting cold yesterday.

was this a kit from Raceboy? he may be the one to ask.

I was under the impression that you needed to control boost manually and not have the cycling valve. I know mine has been gone for a loooooooong time...MBC for me.
