I'm still having a few issues with starting my Gen 2 3SGTE when cold. Its got a Wolf3D V4 EMS, and standard ignition and injectors for now.
Here are my current settings :
Ignition Timing when cranking : 8.8 deg BTDC
Starting Fuel Rate : 3ms
Initial Fuel Pulse : Activated with 5ms Add-on
Post Start Enrichment : On, Inj1 Linear Mode with a 1.2% Decay Rate
Then I have an approx +26% fuel modifier on for around 20 degrees Engine Temp (typical cold start at this time of year).
