Ok, I made some progress. I got my fuel pressure up to 22psi. I got the DA connected and emulation working. What would be the best ADX for data logging, or does it matter? I'm such a newbie at engine tuning, I just don't have the touch, feel, smell experience to know how the engine is running. What parameters have to be met for it to go into closed loop? I feel I will really be relying on O2 reading to do any tuning. I'm going to do some more research for now, If anyone has any advice or tips, I'm all ears.
