Hi everyone. My gti refuses to start from cold unless I advance the timing to full advance on the distributor. Once the car is started and getting warm I return the timing to near stock. Once fully warm starting is easy. I've read other posts on the topic but none match my case. I'm no mechanic, I just tinker here and there. The car has a few mods: 60mm tb, oil catch can, cultus headers, 2"exhaust, lightened under drive pulley. I'm using the stock chip now (was using Tom's 11) so I can add a lil nitrous. Those with knowledge/experience please help.

It sounds like it could be the Electronic Spark Advance system at startup. I would run through the standard series of test to make sure your ECM is in good operating condition. Considering you have messed with the ECM that is definitely where I would start.
No codes?

Also make sure your water temperature sensor and air flow sensor are working correctly.

good call!

i had a no start situation this summer that turned out to be an out of range coolant temp sensor.

Problem solved. Turned out to be faulty wiring coming from the distributor.

Which most likely is part of your spark advance system. Glad you found it.
