Hondata s300 random lean
So some background, im no stranger to the forum, iv been having many bugs with my set up after installing the CPR. So after finally get the CPR to work i was having that drop out issue. Found out it was ECU. Cleared that up but then the car would randomly go lean and even die. Thought maybe it was my hondata board no problem i wanted to upgrade the V3 got that back and still did it but it was getting worse. Stopped the dieing issue by replacing the main relay, but the car still randomly like to go lean so where im driving down the highway and cant drive and have to pull over. Im running out of ideas on what it could be iv checked9 the wiring. Im running ID2000. Here is my calibration with datalogs doing it and not doing it.
Have to go to the Hondata site because i cant upload the files here.

This is not a random lean. Its fuel cut off from decel but your idle isn't tuned right so it dies. You need to tune your idle and fuel overrun settings.
As mentioned on the hondata forum check your fuel pressure to make sure it is consistent.
Side notes:
1. You may want to review your low cam ignition timing map, your timing between column 14 and 15 don't make sense.
2. Your battery offsets don't appear correct for your injectors.
3. Your fuel maps could be smoother.
