Default Base map timing - Link ECU - 0deg?

Hi Guys

After doing my 949 coolant reroute I need to reset the CAS timing. Most instructions I have seen suggest setting base map timing to 10 deg.

My g3 Link ECU has a base map field, do I just change this to 10 deg in the ECU, physically set the timing to 10 deg with the timing light via CAS adjustment and then reset the ECU field back to 0 deg?

That sound about right?

Also, from what I gather for the N/Aspirated I "believe" they advance the ignition (4 deg?) for performance gains, I presume this isn't advisable with a turbo....? Yep, but I am getting there slowly. (theres a lot of info to pour through here...)

Mark.

There should be a way to lock your timing in the LINK so that you can point a timing light on it and make sure the CAS outputs what the LINK thinks it should be at. Once synced, you'll unlock the timing form the LINK.

What you should have done is simply marked the CAS before removing it, and then put it back in the exact same position.

your LINK runs off its own timing map catered for your turbo application. If you want to advance or retard timing, you'll adjust the actual timing numbers cell by cell.

You should probably refere to the user manual on both subjects.
