Well i have a few questions about how much timing i should be running on my b6t.
I asked a fellow employee about it and he said i would have to figure out how much timing the Sohc ecu adds as the rpms increase.
So does anyone have an idea?
Also Im only running 12* of timing on the b6t at the distributor. Should i be running more? Im going to give it a try wether or not i get an answer i just wanted possibly for someone from experience to guide me in the correct direction.
Thanks guys

Well this is what myself and another turbo BP guy are running

12-13 original timing than -.5 degree for every lb of boost. I am using a BTM to make the corrections but my base timing is 11 right now.

Well I do not have anything to control the timing right now.
Ill be megasquirting soon.
Do you think i should retard my timing? a couple of degrees?

How many psi are you running? I have noticed it I retard it more than 1 degree if I am under 5 than I lose power. So if you are running 4-5 I don't think so. Anything over that go ahead and retard it 1 or 2 degrees

yea im running 14 lbs.
Now when i checked my plugs i didnt see any metal specs, now that was only after about 15 miles.
So what your saying is i should lower my timing down to around 10*?

I thought that if you ran the SOHC ecu, you didnt need to retard the timing since the SOHC has less advance than the DOHC one.

that is true. But it is suggest to only run it at like 15-20 psi
