Oft has far easier to use logging and real time display, tuning alerts ect. which tqctrix does not.

KoolBRZ My car is still STOCK. Yes that sucks to hear I know. It wont stay stock for long. Fact of the matter is I did not even know that there was a way to get into the ECU until I stumbled upon this forum a month ago or so ago so I am new to this forum. I got the Tactrix because I blew my yearly budget on my M3. I think the OFT is GREAT. Simply great. I gotta wait though. The work the OFT guys have done is mindblowing but take this: OEMs spend two years calibrating something and they still cant get everything right. The OFT folks got two - three weeks to do the same. So we continue where they left off.
I forgot you were on the Phanton ESC. If you are boosted even slightly the gains you will see from 100% DI will be far more than those with NA will see because earlier with 50% PFI you were probably just short circuiting fuel into the exhaust for no reason. Short circuiting fuel is also bad for exh and CAT because the fuel dumped will burn up there causing heat and stress. But by going DI you may now see some lean-ness in the exhaust being picked up by the O2 sensor but that is okay.
Regarding AVCS or timing it is an altogether different topic and we should start a timing discussion like this PFI/DI. In short though with even a slight boost your timing should be slightly (2-5 deg) more advanced (open and close earlier) than stock timing depending on how much boost you are running. With a lot of boost it will be more advanced. I can explain why in another timing thread.
