Lean When Downshifting - Cant Fix iT (te 3 bar)
 

I got my car running absolutely perfect this last 2 weeks and just halls ass and runs great as far as a/f's go all over the map, part throttle, idle, boost etc

But this week i hooked the wideband back up in my car and noticed that when I downshift/ compression brake, the car runs VERY lean, like off my sensors limits lean 19.4+

You can downshift at any point in any gear, I usually do it in 4th to third to slow down and roll around and the rpms are at about 3K, vacuum is in the -22 region. As soon as you downshift and are off both clutch and throttle itll start out @ 14:1 and the numbers just start going leaner and leaner until it pegs out the gauge and I pull it out of gear. Ive tried dumping fuel (15% so far) int the -22 area and its surrounding cells but it just wont richen up

The car is running ng55 turboedit on a gm 3 bar and dsm 450's, first time tuning a car so I may be missing something.

Heres my map if it makes a difference

hondas shut off the injectors completely over 1100-1200 rpm when theres 0% throttle

what you are describing is normal and nothing to worry about

Yep, at that point there is literally zero amount of fuel going through your engine and it's only pumping air.

:y :y

Pretty much standard practice since the inception of electronic fuel injection.
