engine spec:
b230ft with
90+ turbo manifold
ebay t3t4 turbo
Kl racing t2 cam
compression ratio 9.5
1226cc injectors
The MAT air density table is set 102 at 0 deg Celsius and 100 from 20 to 50 deg Celsius
I'm having trouble with hot restarts, The AFR swing from 12:1 to 22:3 and the rpms are swinging a lot to. It does the same thing when increase the rpm and i hold the throttle steady. I have tried increasing the ve and changing the dead time if that was the issue but no change. Tried changing the after start enrichment with no change, also tried changing the fuel pressure but still no change. Even tried running the fuel pump all the time but no.
The AFR swing a lot. but the pw is going up and down to trying to compensate almost. See the log.
So what can cause this to happen?
Tune and logs of the oscillations
should work now.
