Was just comparing several pre and post cam fuel trim tables - with pretty much same target tables.
The WBO2 piggyback is pulling fuel in a lot of spots. Which means the sensor is seeing more fuel.
Given that I know lift and duration is are increased, my thought is since I am on stock ign timing, the fuel isn’t being burned before escaping the more open valves, and the system is leaning mixture.
Just yanked the ecu and mailing it out to have ign, rev, and speed limits removed.
Burn fuel sooner, more force on piston, leaner reading on exhaust sensor, more fuel added to compensate and therefore burned, win!
This story isn’t over yet.
