lean sync/async threshold
Ok… I’ve got many questions, but I’ll start with this one.
It seems whenever I’m near the async to sync threshold during light cruise my NB O2 spikes almost off the charts. It doesn’t matter weather it’s in sync ready to go to async or vise versa. When I adjust the min async pw I get massive rpm swings at idle. When I adjust the injector bias I can’t pull enough fuel out of the VE tables for it to idle with out raw fuel pouring out the tail pipe. Would anyone happen to know what’s going on?
My setup;
355ci
Vortec Heads
2” TBI
90 pph injectors
Stock fuel pressure (10psi)
8746
Cam .423/.446 lift, 110* Valve Sep
T56

Then, you'll know what good code is like to work with. I'd tell you how good some it is, but then I'd have to shoot you.
It's really that good, IMO.
